Biological Roots of BehaviorChapter 2 (pp. 40-64)
Motivated Behaviors
Homeostasis
Autonomic Nervous System: Activation and Arousal
What are Motivated Behaviors?
Behavioral Neuroscience
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:
Obesity: Homeostatic Failure / Leptin Deficient and Resistant
Can we identify specific brain areas associated with emotion, including aggression?
End: First Class Lecture
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
