Document Summary
Cyclic physiological processes cycle is defined by period one full cycle is the period. Circadian: circa (around) + die (one period/day); evolutionary advantage of timing a biorhythmic event to day/light and night time chronobiology: field of rhythms/biology. Gh release : growth hormone, peaks during the night. Polysomnagram: when you do sleep research, a group of dependent measures is recorded that are recorted as this: polysomnagram. Ecg/ekg: sometimes heart rate and dynamics of heart contraction. Edr- skin conductance: transmit and receiving electrode to finger and sends mild current that you cant feel and the measure is of skin resistance to electrical flow and that resistance is driven by sweat gland activity: automic activation. Pneumogram: respiration genital blood flow (vaginal probe or plethysmograph) most common is eeg. Basic rest-activity cycle (kleitman) the brain is designed to go through these cycles if you look at various measures of cortical functioning, 2nd to be discovered in importance in arousal.
