Glucoreceptor Signaling Adipoise Tissue and Leptin Examples of Peripheral Signals:

Obesity: Homeostatic Failure / Leptin Deficient and Resistant

Can we identify specific brain areas associated with emotion, including aggression?

Psychology: Introduction to the Biological Perspective Motivated Behaviors - Eating Behavior Aggression; Response to Threat Sex Behavior Drug-Seeking Behavior

Sex Behavior Focus on Hormones and the Hypothalamus

Other Motivated Behaviors?

Drug Seeking Behavior

Intracranial Self-Stimulation (ICSS) Rats lever press for electrical stimulation into brain Brain sites may mediate natural rewards (food, water, sex) Note: Brain stimulation also evokes feeding, drinking, maternal and sexual behaviors
