Motivation and emotion/Lectures/Brain and physiological needs
Lecture 03: Brain and physiological needs
This is the third lecture for the motivation and emotion unit of study.
 | This lecture is complete for 2024. |
Overview
[edit | edit source]This lecture:
- explains the role of brain structures, neurotransmitters, and hormones in regulating motivational drives
- discusses physiological needs, particularly thirst, hunger, and sexual motivation
Take-home messages:
- The brain is as much about motivation and emotion as it is about cognition and thinking
- We underestimate how powerful biological urges can be as motivational forces when we are currently not experiencing them
