Document Summary

Drives are reversible internal conditions that orient individuals toward specific types of goals. Notes: behavioral states: slower changes in sensations, perceptions, thoughts and muscle movements that modulate and help direct rapid changes. Brain reward systems mediate three aspects of reward: wanting, liking, and reinforcement: the medial forebrain bundle and nucleus accumbens contain essential pathways of. Hunger is a regulatory drive controlled by neural hormonal and sensory factors. Notes: feedback control- system that maintains homeostasis, hypothalamus: appetite control. Sex is a nonregulatory drive powerfully influenced by hormones. In most nonhuman females mammals, ovarian hormones promote sexual drive at the time of fertility, apparently through action on the ventromedial hypothalamus. In women and some other female primates, adrenal androgens promote sexual receptivity throughout the ovarian cycle. But sexual proceptivity appears to increase at the time of fertility, perhaps because of increased androgen production at that time. In mammals, prenatal androgens masculinize and defeminize the developing brain.
