Document Summary

Theory of mind- we have own thoughts, another organism has own thoughts different from us. Electroencephalograph (eeg):level of electrical activity going on in your brain through use of this or use erps. Eeg x= frequency y=amplitude. records activity in the brain down to millisecond but cannot record where. Circadian rhythms: internal clock helps regulate sleep/wake cycle, regulate when we"re hungry, adapts to environment. Helps explain jet lag our circadian rhythms is thrown off by time zones. A day per time zone to get over jet lag. Stage 2 sleep: sleep spindles and mixed eeg activity. Sleep spindles increase in amplitude, also more frequent. Stage 3 & 4 sleep: slow-wave sleep: progressively more delta waves . Delta- higher amplitude and less frequent (stage 4 is deepest sleep) Rem sleep: low-voltage, high freq delta waves. When we are younger, we are dreaming more-- more rem sleep. Rem sleep is important or else you start hallucinating or die.
