Talk:Phase response curve

message: The term 'acrophase' is ambiguous here with respect to the illustration.  It could either refer to the hormone level that triggers the precipitous climb from delay to advance, or it could refer to the hump over the van in the diagram legend 'advance'.  I was unable to confidently map the textual description to the diagram in less than a minute of hard thinking. MaxEnt 18:30, 25 June 2007 (UTC)
replies: text: I'm wondering if the article could be improved by just not using the word "acrophase" at all.  Anyone new to the concept of a PRC is going to find it confusing enough.  It's fine that the curve is described as sigmoidal, an S-curve, as that is well-known.  "Acrophase" apparently just means the peak and the nadir of such a curve.  Why not just call it that.  I'll attempt a bit of rewriting.  I won't be insulted if it's reverted, as I just barely understand this stuff myself. Hordaland 19:43, 16 September 2007 (UTC)

message: The article talks about how the window for sleep phase advancement is 4 hours total (2 hours before and 2 hours after spontaneous awakening) and that the best time to try it is after spontaneous awakening. However this article on teens and sleep cycles recommended using light therapy 2 hours before natural awakening time.

It seems doing it 2 hours before could be counterproductive, if you are off by an hour in the wrong direction it might cause a sleep delay instead of sleep advancement. Either way, I'm not sure if doing light therapy at spontanerous awakening is considered the de facto best time for sleep advancement light therapy.

thread_title: Light therapy after spontanous awakening

message: Phase response curve can be applied to any oscillatory system to describe how a perturbation changes the phase of the oscillation. I do not know the history of the terminology, but it would be nice if someone can fill that up. In physics and computational neuroscience, there have been quite a bit of work for PRCs.

replies: text: Interesting comment, thanks.  It would be interesting to know when/where the term first was used.  I've only seen PRCs in regard to biological circadian rhythms, probably because that's where I've looked for them :-).  Here is a source for other areas of use.  I don't know if it is allowable here, but it's sources may be.  --Hordaland (talk) 16:25, 12 August 2008 (UTC)
replies: text: Yes, that scholarpedia article is a good example. Perhaps, I can asks some of my physicist friends to put some mathematical details to this article. :) --Memming (talk) 14:13, 17 August 2008 (UTC)
replies: text: It was I who credited Dr. DeCoursey with "inventing" the PRC in 1960, sourced to ScienceBlogs -- which, thankfully, no one has argued with.  But I meant, of course, the use of the PRC as a tool in chronobiology.  I hope you find out more about it in other fields; that would be interesting.  --Hordaland (talk) 19:05, 17 August 2008 (UTC)

message: I've long thought this page was too much of a mish-mash. Looking at it now, I'm tempted to factor out the chronobiology to a page titled chronobiotic phase response curve or chronobiotic PRC (I'm tempted to let the former redirect to the latter).  
This is the kind of mish-mash that earns an article the long-term cold editorial shoulder. It's so disorganized and awkwardly straddled, one is reluctant to dive in for a quick edit, and with no quick edits, substantive edits rarely follow. — MaxEnt 02:10, 16 March 2017 (UTC)
