CIRCADIAN RHYTHMS
3 main properties: 1- 24h period. 2- Endogenous (rhythmic responses continue even in absence of stimulation) 3- Entrainable (rhythms can be reset/adjusted by exposure to external stimuli)
Study: rat has access to running wheel -> turns of wheel recorded on chart recorder, plots each wheel rotation as tick on chart -> each line represents one day’s activity -> activity plotted for month under no light 6am-6pm, rat shown to be active during dark hours of day-night cycle
