Somewhere in the brain, a regular series of pulses was being generated. When the brain needed to time some event, a gate opened and the pulses moved into some…

When Clocks Go Bad

Today in PLoS Genetics: a nice review of some interest to my readers: When Clocks Go Bad: Neurobehavioural Consequences of Disrupted Circadian Timing by Alun R. Barnard and Patrick M. Nolan: Progress in unravelling the cellular and molecular basis of mammalian circadian regulation over the past decade has provided us with new avenues through which…

In the Journal of Circadian Rhythms: A new approach to understanding the impact of circadian disruption on human health (pdf): Background Light and dark patterns are the major synchronizer of circadian rhythms to the 24-hour solar day.

The Amplitude Problem

If you are one of the few of my readers who actually slogged through my Clock Tutorials, especially the difficult series on Entrainment and Phase Response Curves, you got to appreciate the usefulness of the oscillator theory from physics in its application to the study of biological clocks. Use of physics models in the study…

Sleep Schedules in Adolescents
