== General Stuff ==


People: I m not english speaker but i think "sense" derseves a desambiguation page. Sense is not only corporal senses, we say also "nonsense" for a silly thing, "commonsense" etc


EntmootsOfTrolls would have liked this article to be part of [[User:EntmootsOfTrolls/WikiProject Body, Cognition and Senses]], which provides guidelines for articles on those topics, and seeks stronger cross-linkage and cross-cultural treatment of all of these topics.

This is a central article in that project. It seems that not all the other articles on the senses really fully explain their relation to other senses well - and often assume the biomedical model too much. [[Pain]] for instance had no links to [[pain control]] and mentioned no way to control pain other than drugs, saying that "drugs control pain". This is not good. We are not pushers. We have a lot of this kind of stuff to clean up.

how about dissecting the page into overview and <b> links </b> to the respective senses? i think there's already too much detail info in here...

== Colour and Energy of Light ==

:different [visual] receptors are responsible for the perception of colour (the frequency of light) and brightness (the energy of light)

Can anyone support this claim? What I know about visual perception suggests that photoceptors do ''not'' divide nicely into those concerned with frequency and those concerned with color. If someone wrote this in light of the distinction between rods and cones they are sadly mistaken; cones as well as rods process "brightness". If no one can explain this, the passage is getting removed. --[[User:Ryguasu|Ryguasu]]

::Read [[vision]] and [[visual perception]] - it's a lot more complex than just that.

== Sense of being stared at ==

Should we mention the potential of a "sense of being stared at"? Research backing it is laid out at [[morphogenetic field]]. It's not widely accepted and we should say that, but it's rare that anyone actually proposes a new sense, so I am inclined to think it should be here.

: A morphogenetic field has yet to survive any rigorous scientific testing, so I don't think it can be seriously entertained here. When a medical textbook accepts the existence of the morphogenetic field, then so should this article. The article is really a generalist overview of a physiology topic. [[User:Manning Bartlett|Manning]] 13:36, August 12, 2005 (UTC)

:: I think this page should include a category for senses that have not yet withstood rigorous scientific testing. Remember, the policy is NPOV, not SPOV (scientific point of view). The "sense of being stared at", the ability to see auras, tele-empathy and medical empathy, as well as the "sense of direction" (possibly a poorly developed form of electroception -- after all, electroception had to come from ''somewhere'' and it's a bit naive to think that, while the platypus has a highly developed sense of electroception, as do many birds -- invluding non-migratory ones (just try holding a magnet up to a cockateil or a parakeet and watch its reaction!), and many fish as well, that no other animal in the world has even a rudimentary version of this sense. Didn't a previous version of this page once state that humans had the same minerals in the brain that exist in specialized organs of animals with a dictinctly developed sense of electroception, and that this is why we humans can sometimes "feel" where north is (or soutn, in the southen hemisphere)? Just because humans have no specialized organ for this particular sense, doesn't mean they don't have some vague, undeveloped, and barely perceptible sensation of electromangetism aside from that gathered from other senses (like hairs standing up on end or ears ringing in the presence of electrical fields). Evolutionarily speaking, some primitive precursor to a full-fledged sense must exist before a sensory organ dedicated to it evolves, and given the sheer variety of animals with electroceptic sensory organs, it seems reasonable to assume that many other animals have such an as-yet-undeveloped precursor to this sense. This could also be related to the ability to sense auras (interpreting stimuli for which we have no dedicated sensory organ in the form of a sense we actually can process consciously, like vision).

:: In short, there is no reason not to include a section on this page for hypothesized yet scientifically unproven senses. Like I said: It's NPOV that counts here, not SPOV. If substantial numbers of people believe in certain senses, it is not our place to conclude, due to lack of scientific evidence, that they are not actual senses because they do not exist and exclude them from this page. Rather, it is merely our place to point out that scientific proof for these presumed and hypothesized senses has not yet come forth. --[[User:Corvun|Corvun]] 13:59, 6 September 2006 (UTC)

::: It would be inappropriate to include such a section. The scientific point of view is objective and skeptical, and hence is what must be followed for NPOV. Such a section is not justified by your claim that there is a 'substantial number' of people who believe it. Substantial numbers of people can be wrong anyway. Your own conjecture is also no reason to include this sort of thing. [[Special:Contributions/124.171.189.135|124.171.189.135]] ([[User talk:124.171.189.135|talk]]) 13:56, 20 July 2008 (UTC)

== Polarization of light ==

What about perception of polarization of light, by fish? Is there a one-word name for that?

''Yes, I hear [[bee]]s and some other insects use light polarization for navigation. Supposedly even humans can sense it directly [[Haidinger's brush]]. Since it's sensed by the eyes, perhaps it should be classified as one kind of enhanced vision?''

== Taste ==

The book "Fast Food Nation" lists a sixth gustatory flavour called "astringent". Presumably, this is the flavour of mouthwash and some medicines.

: I haven't found scientific info about this, only some "holistic" stuff. [[User:R3m0t|r3m0t]] 17:50, 19 Mar 2004 (UTC)

== Infrared light ==

I added something about pit vipers and boas and their ability to sense infrared light. Is their a name for this sense? Also, are their any other animals with this sense? [[User:CyborgTosser|CyborgTosser]] 17:46, 4 Jun 2004 (UTC)

: Isn't this just a sense of sight, developed for a slightly longer wavelength than humans? --[[User:Mintie|Mintie]] 23:32, 22 May 2005 (UTC)

::Physiologically this is still the sense of vision, except that the receptors are tuned to a wider frequency (as Mintie said). It's no difference to the fact that dogs (and other animals) can hear above the 20kHz audio frequency range.[[User:Manning Bartlett|Manning]] 06:06, August 16, 2005 (UTC)

:::But the article states that ''This sense is in addition to and distinct from normal vision''. Which is what I wanted to ask a question about here. But it's already been said. So I'll change that (and move it up). [[User:DirkvdM|DirkvdM]] 08:46, 28 September 2005 (UTC)

::::: The [[Crotalinae|pit viper]] article specifically mentions special [[thermoreceptor]] sensors, which are *not* the eyes. That makes it a different "sense", right? --[[User:DavidCary|DavidCary]] 21:23, 6 January 2006 (UTC)

:::Also, isn't there a lobster-like animal that has very complicated eyes, sensing not just many more frequencies but also some other aspects? I vaguely remember something like that, but [[lobster]] doesn't say anything about it. Does anyone know which animal this is? [[User:DirkvdM|DirkvdM]] 08:46, 28 September 2005 (UTC)

:::: You're thinking of [[mantis shrimp]]. 17:12, 19 March 2008 (PST)

:::: My understanding is that a photon has only two "aspects" -- frequency and [[#Polarization_of_light]]. --[[User:DavidCary|DavidCary]] 21:23, 6 January 2006 (UTC)

::::: Indeed, and certain compound eyes have the ability to detect the latter, as discussed in that article. On the matter of infrared, where there exists a separate sense organ, and a different part of the brain is involved, this will indeed be regarded as a unique sense. What is not required here is for physicists (of which I am one) to wade in and smugly declare that this is just light, therefore the same sense as vision. To do so misses the definition of a sense totally. Therefore, and because it interrupts the flow and looks like somebody trying to squeeze their tuppenceworth into the article, I've removed the sentence "Infrared senses are, however, just sight in a different light frequency range." --[[User:Cmsg|Che Gannarelli]] ([[User talk:Cmsg|talk]]) 12:32, 14 August 2008 (UTC)

== Time ==

"Sense of time passing" is sometimes named as a sense, often in conjunction with (though not related to) balance.

== Pain ==

As a common pleb, I have always thought that pain was an extreme manifestation of the other senses, and not as a separate sense. Imagine pressing a spike lightly against your skin. It may not be pain but you can feel it. Press harder, and it becomes pain. There's a grey area of discomfort between the feelings of touch and pain. Similarly with heat and cold, sound, light, balance (motion sickness etc.), even smell and taste (unpleasant tastes/smells such as strong chemicals). The article on [[Nociception]], if I understand it correctly, states that there are specialised pain receptors (separate from those for touch and temperature), which seems to refute my idea. Either way I think it's a common enough (mis)conception that it could do with refutation/support in the main article. --[[User:Mintie|Mintie]] 23:32, 22 May 2005 (UTC)

:The pain that comes with pressure is what caused people to think that pain was simply an overload of the touch senses. You can see that it isn't by considering the pain of heartburn, muscle stress, and a rash. Nociception is neurological quite distinct from tactition. A deeper explanation of how pain and touch differ would be useful - I'll put it on my to-do list. [[User:Manning Bartlett|Manning]] 13:38, August 12, 2005 (UTC)

For other senses, the article indicates the stimuli that are sensed, e.g. light, pressure, chemistry, temperature, acceleration. What stimuli are sensed by pain sensors? Is pain cognitive/post-sensory or are there unique pain sensors that "fire" only under limit condition (as protection against possible damage)?[[User:Cwfv|Cwfv]] ([[User talk:Cwfv|talk]]) 00:33, 21 April 2009 (UTC)
:Everything about that is in [[nociception]] .[[User:Viridiflavus|Viridiflavus]] ([[User talk:Viridiflavus|talk]]) 06:33, 21 April 2009 (UTC)

== Bacteria ==
Guess what???
Ice cubes in fast food restuarants and hotels and airplanes have more bacteria than their pottys!!!!!!
EWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW!!!
"Magnetotactic bacteria build miniature magnets inside themselves and use them to determine their orientation relative to the Earth's magnetic field." What possible reason would a bacteria have for doing this? Is it just a quirk of evolution? --[[User:Mintie|Mintie]] 23:32, 22 May 2005 (UTC)

It would probably be done to ensure some sort of vague geometric pattern in the growth of the bateria... sorta like the way atoms line up in a crystal--[[User:Bill|Bill]] 23:32, 21 Jan 2006 (UNSW)

== Other senses ==

As a half-serious suggestion, what about more ethereal senses such as the sense of morality or outrage? See http://angryflower.com/sensib.gif for a laugh. Any other thoughts? --[[User:Mintie|Mintie]] 23:32, 22 May 2005 (UTC)

And what about the so called "sixth sense" [[User:Hallenrm|Charlie]] 08:27, 18 November 2005 (UTC)

So-called "[[common sense]]"

== Nausea is also distinct ==

While nausea can by accompanied by dizzyness (probably part of Equilibrioception) and pain it's quite distinct.
Having to go pee is another, but that doesn't sound too scientific.
-rm

The sensation of a full bladder (having to pee) is a real sensation but is not necessarily a correct indication that the bladder is full. After a prostrate operation my doctor gave me medicine that was to "retrain my bladder" into knowing when it was really full versus when it thought it was full. I don't know anything about the mechanism behind that feeling or how the medicine works.

Perhaps along similar lines, there is a sensation one feels when having to defecate. If that feeling is ignored for a long enough time, it will be replaced by pain (cramps).
- btm

The sensation of the relative fullness of the bladder, bowels, or stomach is a real human sensation, corresponding to a real phenomenon: they should be included in the list. Sense is (somewhat) independent of cognition; the conclusions you draw based on what you appear to see or hear or feel may be different than the sensations themselves.

== Balance ==

Why not simply call balance the sense of acceleration? Gravity is accelaration. (see relativity.) All forms of accelartion is sensed with your sense of balance, and nothing more or less.

:Fair comment, but you'll need to discuss it with the physiologists, not us. We just report what the term is, we don't decide. While you are at it, aske them why on earth we needed a word like "gustation". [[User:Manning Bartlett|Manning]] 06:04, August 16, 2005 (UTC)

== Senses and Perception ==

If senses include such things as the statolith and magnetotactic bacteria, shouldn't it also include [[phototaxis]] and [[chemotaxis]]? in other organisms. Certainly this can be divided by phylogeny, but if it is a generalized article on the senses, shouldn't we include sections for the detection of, for example, red to far red light ratio in plants? Phototaxis in birds (the so-called third eye, because of light penetration of the skull? Just out of curiousity. Thank you.[[User:L Hamm|L Hamm]] 03:15, 22 August 2005 (UTC)

== "Types of Senses" ==

Hi. I've taken the (bold?) step of deleting this section. I looked carefully at it and couldn't see any information that wasn't included in the "List of Human senses" section, which is generally much better, and properly wikified.[[User:82.13.223.11|82.13.223.11]] 16:28, 7 November 2005 (UTC)


== Can plants sense too? ==

The answer is of course "yes", but unfortunately this topic is missing. I have inserted a line in the non human senses. I will add more in due course of time. 08:20, 18 November 2005 (UTC)

== Questionable sentence ==

The following is highly debatable:

<blockquote> "No life form is without any kind of sensing faculty."</blockquote>

What of amoebas, bacteria, or (also arguable since they're often not thought to be alive) viruses? The sentence also advocates by implication the idea that sense is unrelated to cognition, which it shouldn't do, since "there is no firm agreement amongst neurologists as to exactly how many senses there are, because of differing definitions of a ''sense''." The article immediately goes on to make the assumption that a sense requires a brain by including brains in the definition in the next paragraph. --[[User:Mr. Billion|Mr. Billion]] 17:19, 11 December 2005 (UTC)

''I'm no expert. But I see no contradiction between saying that neurologists have various definitions of a "sense", while also saying that neurologists all agree that a "sense" does not include various higher-order perceptions such as "wetness" or "distance perception" or "" that are derived from combining several sources of information. --[[User:DavidCary|DavidCary]] 21:23, 6 January 2006 (UTC)''

== taction vs tactition ==

i don't really know a lot about html editing, but I changed "tactition" to say "taction" since it represents the idea presented and tactition is not a word.

== other above-average abilities ==

There are several articles about above-average human abilities.
Should we list them in the [[sense]] article?
--[[User:DavidCary|DavidCary]] 21:23, 6 January 2006 (UTC)

* [[supertaster]]
* [[tetrachromat]]
* "some individuals are able to hear up to 22 kHz" -- [[hearing]] (is this the same as [[Golden ear]] ?)
and perhaps
* [[polydactyly]]
* [[Haidinger's brush]]

== Sense of self ==

What about human being's inherit sense of their own thoughts? I cant believe ive never seen this discussed in its wholeness, but i believe that its one of the very few things that separates human from the other creatures - self awareness.. which is really just having one's own thoughts re-run through a sensory module (of the brain). this way, conscious is the resulting loop of thought>sense of thought>thought resulting from sense>sense of this thought>etc; and subconscious are the multitude of many thoughts that we are not 'consciously aware' of (not sensed). -Bill

: A worthy topic, but unrelated to this article. This article is about physiological sensory perception - ie, how sensory nerves (external to the brain/CNS) relay information to the brain for processing. Being self-aware ("''cogito ergo sum''")is a process of abstract thought (which, by definition, means brain functions independent of external stimuli). [[User:Manning Bartlett|Manning]] 01:35, 18 April 2006 (UTC)

== Echolocation? ==

Is echolocation really a bona-fide sense? I mean I can tell the direction of where sound comes from but isnt that a just post-sensory function of hearing? As far as I know echo location is just a more advanced post-processing of hearing. [[User:129.42.208.182|129.42.208.182]] 21:34, 4 April 2006 (UTC)

: It certainly isn't a sense in humans, but the ability is observed in many animals such as bats. As noted in the article, the question of whether or not echolocation is a unique sense or simply a post-sensory cognitive interpretation of hearing remains to be resolved. [[User:Manning Bartlett|Manning]] 01:30, 18 April 2006 (UTC)

:This article seems to prove that Humans are capable of performing echolocation.

== Rare Disease ==

There is a disease, I forget the name, that exists where people 'hear' colors. A while back, the news was showing an autistic girl playing the piano and announcing the colors she was seeing. What is this disease called? It should be mentioned, at least in the links. [[User:207.179.172.220|207.179.172.220]] 16:27, 28 July 2006 (UTC)

It's an abnormal binding of sensory input. I'm not sure its a disease, per se. It happens when a particular input (say yellow) is associated (incorrectly) with another (say 5). In this example, when this person looks at a bowl of apples, nothing particularly interesting happens. But as soon as they are aware that there are 5 apples, there is a yellowness associated with that input. They know the apples are red (or green, or i suppse yellow, but we'll say they're red) and they would say "red" if you asked them what colour they are. But there is also a "yellowness" associated with them. The reverse may or may not be true. I forget what this phenomenon is called. [[User:Mike.lifeguard|Mike.lifeguard]] 03:00, 6 November 2006 (UTC)

I beleive this phenomenon is called synesthesia, there is a seperate wp article for it. It isn't an extra sense, it's more that one sense triggers a feeing in another. I believe this phenomenon occurs in many cases of autism.

== POV/Contradiction edit ==

I've removed the bolded sentence from the article:

:There is no firm agreement among neurologists as to exactly how many senses there are, because of differing definitions of a sense. In general, one can say that a "sense" is a faculty by which outside stimuli are perceived. School children are routinely taught that there are five senses (sight, hearing, touch, smell, taste; a classification first devised by Aristotle). '''There is another highly debatable 6th sense but that is pretty much voodoo and conjecture.'''

:It is generally agreed that there are at least nine different senses in humans, and a minimum of two more observed in other organisms.

Calling it 'voodoo and conjecture' is definitely POV, and leads to confusion with the sentence that follows -- after all, if there are ''nine'' senses, then there must be a ''sixth!'' -- Heath [[User:69.174.67.197|69.174.67.197]] 00:07, 31 July 2006 (UTC)

I would not call the sixth sense as voodoo or myth, as it is common, first of all everyone has a sixth sense organ without even knowing it exists, which is undergoing scientific research such as how one can sense light and dark in a separate room etc which is governed by the organ within the center of the brain, which is dubbed the perennial eye "Third eye" etc..
Here are 3 links to get you interested if you are doing research in having more ground evidence of the sixth sense.
[[Third eye]]
[[Pineal gland]]
[[Parietal eye]]
Then also a book of interest to read is intelligent design by Rael, and especial Sensual Meditation (activating sixth sense), which could be a basis or foundation to start research on at [http://rael.org Raelian Movement website] to get the pdf documents, for me it works, but that is debatable but it is in correlation with:
[[Indriya]], [[Ayatana]] which has been derived from ancient culture. If one can understand and think, how many of the inventions and ideas are used today invented by the far eastern peoples, for example, which is quite blatant and destructive is gun powder, which was used in battles in the far east before the invention reached Europe(which also is used for artistic purposes of fireworks), and then paper as well in China, so the subject of the sixth sense has to be researched which also could be in correlation with Alpha and Beta waves of the brain, such as the new star wars toy that had been created. But how hair strands working as "aerials" of telepathy is another thing that needs to be researched.. It would be incorrect to completely dismiss the sixth sense organ if it is explained in history and culture, but not not 100% proven, sorry if i rambled, Lotsa Love

== Number of senses ==

If we have 5, or 9, or 23 senses depending on who you ask and their definition, why are not all 23 listed? I think it might be useful to have the senses organized in models. ie. the traditional 5 sense model, and list them. then the updated 9-sense model, and list them. then the fancy 23 sense model and list them. After that, describe them all. Anyone up for it?? ITs certainly not helpful to have a statement that there may be as many as 23 senses in humans, but only see 9 of them listed. [[User:Mike.lifeguard|Mike.lifeguard]] 03:05, 6 November 2006 (UTC)

Actually, this statement appears on [[Olfaction]]. [[User:Mike.lifeguard|Mike.lifeguard]] 03:06, 6 November 2006 (UTC)

:There is no formal "23 sense" model as such, and no two neurologists would fully agree on the model. The increase in number occurs when you treat individual receptors as distinct senses. For example, there are at least four distinct touch receptors, each with their own neural pathway and each attuned to slightly different stimuli. So the decision to call this a single sense or individual senses becomes somewhat arbitrary. [[User:Manning Bartlett|Manning]] 15:45, 23 September 2007 (UTC)

== Sense of Direction ==

Should there be a mention that some humans have a slight sense of direction (most likely based on Earth's magnetic field)? I know this exists from personal experience. Even as a child, all my dreams and memories had a direction to them. I actually found it rather shocking when I got older and heard people say they do not have that perception. Yet, I have encountered several other people who DO have a sense of direction in this manner. Sometimes this sense is stronger than other times, but I can generally sense compass direction to within about 30-45 degrees. It's tough to describe the sensation to those who do not feel it, but it can be best described as north feeling like an "up-hill" trip even on level ground. South is "downhill", and east and west are both "level". [[User:Geekrecon|Geekrecon]] 18:19, 24 November 2006 (UTC)

Update: I did notice that there is a tiny mentioning of Sense of Direction under "Magnetoception". Could something about this be moved under the human section of the article? [[User:Geekrecon|Geekrecon]] 18:21, 24 November 2006 (UTC)

== Animals, earthquakes, tsunamis ==

What about animals that react to earthquakes, tsunamis and the like? --[[User:Joffeloff|Joffeloff]] 01:30, 10 January 2007 (UTC)

==Simulated Reality==
(This is all theoretical)
What if we were eventually able to reproduce the senses sent to the brain? If they are electronic signals sent through the nervous system, then they (might ?) be able to be copied or faked by attaching all of a person's connections to the brain to a machine that could reproduce them. Would this allow this subject to experience whatever we programmed them to experience? It occured to me that if this could happen, you could enter worlds of fantasy.

== Interoception ==

Why does interoception redirect to here? That seems a bit manky what?

== Mental Map ==

I know that there is some sense that is a "mental map" of your surroundings, so you can, say, reach around something and grab something else without looking.

I think there is a study about which of the senses would be the first to lose its function after death. I can't find a link though. Maybe we can add this information to the article. [[User:Leoisiah|Leoisiah]] ([[User talk:Leoisiah|talk]]) 14:26, 7 March 2008 (UTC)

== Proprioception or perhaps Kinesthesia ==

Why is this not mentioned?! It's a basic sense available to humans and fundamentally different than touch, taste, sight, hearing, smell, and balance! 16:56, 19 March 2008 (PST)

== Spelling: recognised vs recognized ==

I will change recognised to recognized because all my dictionaries have the latter. What dictionary does wikipedia follow? -[[User:Tsinoyman|Tsinoyman]] ([[User talk:Tsinoyman|talk]]) 20:30, 19 April 2008 (UTC)

: Both are correct: you might want to see [[American_and_British_English_spelling_differences#-ise.2C_-ize|American and British English spelling differences]]
: Also, I just did a quick scan and saw "colour", so my immediate assumption is that the article is not written primarily in American English, or that it's a hybrid, and it's not good to change the spelling if one system is already in place (I'm sure somebody can provide the right link). --[[User:Stomme|Stomme]] ([[User talk:Stomme|talk]]) 21:11, 19 April 2008 (UTC)

== A bit messy. ==

I am listing my edits of some of the non-sense and lack of, or wrong information.

"The nervous system has a sensory system dedicated to each sense." to "The nervous system has a specific sensory system, or organ, dedicated to each sense."

Because it does.

"However, humans have at least eight different senses (including interoceptive senses), like: thermoception (heat, cold), nociception (pain), equilibrioception (balance, gravity), proprioception & kinesthesia (joint motion and acceleration). Different senses also exist in other organisms (amongst them: electroreception, echolocation, magnetoception, pressure detection, polarized light detection)."

To:

"However, humans have at least seven, and possibly eight, different senses. They are inclusive of the above with the addition of [[equilibrioception]] (balance), [[thermoception]] (temperature differences), and in some a weak [[magnetoception]] (direction)<ref>Magnetic fields and the central nervous system .
Clinical Neurophysiology , Volume 111 , Issue 11 , Pages 1934 - 1935
A . Voustianiouk</ref>. Different senses also exist in other organisms, for example [[electroreception]]."

I removed nociception (pain), proprioception & kinesthesia (joint motion and acceleration), and pressure detection because they are sub-catagories of [[somatoception]]. I also removed polarized light detection becaused it is a sub-catagory of vision.

I removed "Buddhist and Jewish belief systems attribute the sixth sense to memory or mind." because it has nothing to do with this article. <small>—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[User:GeeOh|GeeOh]] ([[User talk:GeeOh|talk]] • [[Special:Contributions/GeeOh|contribs]]) 03:59, 23 May 2008 (UTC)</small><!-- Template:Unsigned --> <!--Autosigned by SineBot-->


==Proprioception and interoception again==
I believe that senses which relate to stimuli coming from one's own body, interoception I believe it is called, should be included, as it seems to have been at some point. The reasoning behind it is that the article seems to define senses as something that "has a specific sensory system, or organ, dedicated to [it]". Proprioception, amongst others, is one that definitely has special receptors and that is processed by some kind of neurological system.

This does bring back the problem of the definition of sense, and I think the article should, as has been mentioned before, try to account for the many "definitions" or categorizations of senses. I.e.: classical, external, internal. It already does so to some extent by making the difference between human senses and non-human ones, but really doesn't do much justice to the different attempts that have been made by different parties to list all senses known. Senses, and how to categorize them, do seem to be a subject of great debate, but an encyclopedia, instead of skipping the discussion altogether, should try to mention the better known views on the subject. It doesn't seem to be the case.

I won't go into this myself as I know nothing about the subject, or anything pertaining to biology really. I do hope to spark a change for the better for this article as it's quite messy, and many links to it are broken, i.e. [[Interoception]].

:The paragraphs you refer to were deleted on March 13 2008. I reverted this vandalism and made minor improvements. The paragraphs still need work and references. [[User:Greensburger|Greensburger]] ([[User talk:Greensburger|talk]]) 04:38, 6 June 2008 (UTC)

== Magnetoception again ==
Given that we're citing studies at [[Magnetoception]] stating that there's some evidence of it in humans, I'd like to propose that the article be re-edited to take that into account. Since the information was already released once, I'm not entirely certain it's my place to readd it...[[User:Eoseth|Eoseth]] ([[User talk:Eoseth|talk]])



== Just a little theory on sense evolution ==


Senses evolved progressively one from another (for example, probably photosensitivity evolved from phonosensitivity, etc) in a sort of sense phylogenetic tree, whose presumable root was metabolism. --[[User:Faustnh|Faustnh]] ([[User talk:Faustnh|talk]]) 21:50, 18 June 2009 (UTC)

== Comments on "Sight" section ==

Two comments. The following fragment is IMHO poorly worded:
* ''[...] which is why people see interpreting the image as "sight."''
Somebody who knows their stuff could try and improve on it.

Also, if a note is made that color perception may be considered a different sense, there should be a reference to [[color blindness]] next to the one on [[blindness]]. [[User:Elpincha|elpincha]] ([[User talk:Elpincha|talk]]) 03:26, 4 November 2009 (UTC)
