PSY 0010 Lecture Notes - Lecture 5: Obstructive Sleep Apnea, Excessive Daytime Sleepiness, Slow-Wave Sleep
Document Summary
Altered state of consciousness: forms of experience that depart from the normal subjective experience of the world and the mind. Sleep is an active process with many brain regions showing increased activity. The continuity, patterning, and timing of sleep is essential to the restorative process. Relative disconnection between neurobehavioral systems that are linked in awake state. Brain shows eeg changes in beta, alpha waves, theta, and delta waves. 5 stages of sleep: stages 1 4 and rem sleep stage. Rem sleep: a stage of sleep characterized by rapid eye movements and a high level of brain activity. Electrooculograph (eog): an instrument that measures eye movements. Across our lifetime, we get about one hour of sleep for every two awake. Rem sleep deprivation has the most detrimental effects, followed by slow-wave sleep (stages 3 and 4). Nighttime sleep becomes lighter (less slow wave sleep), more adult like pattern of rem, more prone to external disruptions.
