Abstract

Colin Pittendrigh's model of a circadian clock, involving two coupled oscillators, remains influential decades after its proposal.

  • The model suggests oscillators that respond to the rising and setting sun to adapt behaviors and physiological processes to seasonal changes.
  • Research has focused on identifying these evening and morning oscillators in various species, including insects, rodents, and humans.
  • Technological advancements in biology and neuroscience have enhanced experimental designs aimed at studying these oscillators.
  • The dual oscillator model continues to shape our understanding of the circadian clock located in the mammalian suprachiasmatic nucleus.
