Why Do We Eat?
Examples of Peripheral Signals:
Glucoreceptor Signaling
Adipoise Tissue and Leptin

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
