PSYC 208 Lecture Notes - Lecture 3: Multiple Sleep Latency Test, Middle Ear, Retrograde Amnesia
Document Summary
When blocked using antihistamines = drowsiness: melatonin mildly sleep producing, speed sleep onset; increases in brain. Sleep methodology: in lab computers, slit screens, speakers, adjust display (how fast recording, keep researchers awake. Polysomnography (psg: biomedical recording of multiple physiological variables during sleep, continuous display of data. Blood pressure (bp), systole, diastole; arterial pressure: declines 11-36mmhg during 1st hour of nrem, lowest during n3, rem phasic surges, and very low. Heart rate (hr) measured with electrocardiogram: decreases into stages, with variability, and high peaks during rem, arrhythmias found in rem, angina due to marked alteration of bp + hr during rem. Reading while falling asleep, won"t remember last few pages: low intensity stimuli can interrupt. Rem period: hr, resp. , bp variable, increase/ peak , duration 15-25% of total sleep time. Other sleep determinants: sleep latency: the time it takes from lights out /bedtime to onset of sleep (mslt, sleep period: time from when you fall asleep to last awakening (ex.
