Functions of sleep

Discussion question one: Functions of sleep
Based on your reading and research, which hypothesis or hypotheses on the functions of sleep do you agree with and why? How would you use this explanation(s) to assess a patient who has chronic insomnia, and has already had extensive treatment with hypnotic (sleep-inducing) medications? Respond to at least two of your classmates posts no later than Monday, Day 7.

Discussion questio two:Positive Reward Hypothesis
Use the text and other resources such as the NIDA Website to research hypotheses and models surrounding drug addiction and abuse. Discuss the positive reward (or positive reinforcement) hypothesis of drug abuse and compare it with at least one other explanation of drug abuse. How does the positive reward hypothesis compare with other models of drug abuse in your opinion? How would you use this model to treat a patient who chronically abuses methamphetamines? Respond to at least two of your classmates posts no later than Monday, Day 7.
