Time to think. When to think. Our 24 hour clock

[Double click on image to enlarge]

When do you think the best...and why? I started skimming the article below and quickly realized that it was more than I wanted to know about the circadian pacemaker. Maybe I was trying to read it at a time when my cognitive processes where not functioning at their optimal level (due to my circadian clock).

As noted in prior posts, research has suggested that human beings have multiple timing systems that are active over more than 10 orders of magnitude. At the top is the 24 hour circadian pacemaker/oscillator system, a level far removed from the focus of IQ's Brain Clock on interval and milisecond timing systems. However, the title of this article grabbed my attention...which quickly wanned....zzzzzzzzzzzzz....I need a nap (this is not a reflection on the scholarly merits of the article...just my capacity to sustain interest, arousal, motivation, etc. to read the digest it.)

However, I did find a very nice conceptual figure (and I love conceptual model figures) the authors used to organize their literature review re: cognitive functions impacted by our circadian rhythms. The figure is above (double click to enlarge).

I decided to make this article available to readers in hopes that someone may take the time to read it and summarize it in layman's terms. If anyone would like to make a guest post re: this article, let me know via the "comment" feature. Maybe my fellow blogger at "A blog around the clock" might eventually post something regarding this article (if he has not already).

Your thoughts about our free "natural time in real-time" clock device and associated projects per GreenTyme (dot) org are greatly appreciated.

Especially as how our KInderClock & other chrono-cognitive devices might be used to alleviate Sundown Syndrome in Alzheimer's patients -- and help others also suffering from severe effects of biological clock impairments/misregulated circadian rhythms?
