Circadian rhythm lead
Hi -- the sentence "Circadian rhythms are endogenous and can be entrained by external cues..." seems confusing to me. The words "and" and "but" are both conjunctions having the same logical meaning -- "but" is used in situations where what follows is unexpected in light of what came before. Given that circadian rhythms are generated internally, it will be unexpected that external cues control them, so the word "but" is needed for clarity, I think.
It might help to consider an equivalent case: "The moon generates the tides but the sun also influences them" versus "The moon generates the tides and the sun also influences them". The two have the same logical meaning, but the first is easier to understand.
- Hoping this reword satisfies us both:
- "Although circadian rhythms are endogenous, they are adjusted (entrained) to the environment by external cues called zeitgebers, the primary one of which is daylight."
- (Although the tides are generated by the moon, the sun also influences them.) - Hordaland (talk) 06:31, 8 February 2010 (UTC)

Hey Hordaland, I don't know if you have my talk page watch listed or not but Meodipt, a pharmacist seems to have answered your questions, a lot better than I did. :)--Literaturegeek | T@1k? 16:47, 21 February 2010 (UTC)
