==De Bruin Sequence page==
Hello. I noticed that you had added some details on the use of De Bruijn cycles in fMRI experiments. While what you wrote is correct, I think it would need greater detail for it to be understandable to someone who is not familiar with the application. Given that the wiki page concerns De Bruijn sequences in general, these details of "path-guided" sequences for fMRI are probably too esoteric. I reverted the page back to the prior state regarding fMRI with the hope that folks with an interest in this application can follow the links offsite.

I've placed the cut text below in case you wish to revet the change.

All the best,

********************
In an fMRI experiment, activity at certain frequencies is most easy to detect. By selecting the correct order of stimuli, the researcher can ensure the activity changes of interest vary at the most detectable frequency. A subset of the possible De Bruijn cycles will have this feature. In general the de Bruijn cycle allows the experimenter to maximise the statistical power of the experiment, without compromising on counterbalancing. The method also allows the signal caused by carry-over effects to be maximised, if required.

You need to show with references that it is a notable book. See WP:RS. A book about Signal Detection by P. Eridon would be very unnotable, but this one might be the bees' knees. Needs filling out and referencing for success. Peridon (talk) 18:30, 13 October 2011 (UTC)[reply]

In terms of signal detection, should I have said "cats' whiskers"? Peridon (talk) 18:31, 13 October 2011 (UTC)[reply]

Hi. When you recently edited Event-related functional magnetic resonance imaging, you added a link pointing to the disambiguation page BOLD (check to confirm | fix with Dab solver). Such links are almost always unintended, since a disambiguation page is merely a list of "Did you mean..." article titles. Read the FAQ • Join us at the DPL WikiProject.
