Focus on the Neural Bases of Behavior

Neural Bases of Behavior

Why Do We Eat?

Glucoreceptor Signaling

Adipoise Tissue and Leptin

Examples of Peripheral Signals:

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
