Document Summary
Amplitude increases when many neurons are firing in synchrony. Electromyogram (emg) - same thing, but for skeletal muscles. Beta waves - when listening, attentive to environment. K complexed - large disruption in brain waves when there is a large disruption in environment. Stages 3-4 (slow-wave sleep) - delta waves. Rem sleep - theta, beta activity - triggered by pons (send signals to thalamus, shuts off spinal neurons) See lecture slides for lots of diagrams! Randy gardner - san diego high school student, self imposed experiment - awake for. Decreased memory formation, especially of emotional memories. Rem rebound - lengthening and increased frequency of rem episodes. Lots of physiological effects - basically, everything becomes a clusterfuck. Sleep paralysis - awake & conscious, but body unable to move. While dropping off to sleep (hypnagogic state) Narcolepsy - 1 out of 2000 to 10,000 adults. Sleep apnea (difficulty breathing) - 1 out of 25 adults.
