Document Summary

Basal forebrain when it comes to sleep, is functioning for falling asleep. Depressants and opiates (these are vast categories, so we don"t just have alcohol or heroin) are both similar in that they both induce impaired psychological functioning. A challenge to freud: the mind is a single entity= modular (independent modules in the brain that may interact in some way but there are different parts doing things). Eegs is a way of reading brain activity but not structure. The primary tool used in sleep research tracking where people are. Relaxed/ kicking back: beta waves become higher called alpha waves. Four main stages: theta waves, light sleep, easily woken up, hypnogogic state, light images, rem eeg patterns look like you are awake and alert. Heart rate quicken and everything goes back to the awake level. Alcohol: the experience of being drunk is not really related to alcohol. Objective: can be verified directly, such as an eeg.
