Lecture 03: Brain and physiological needs
This is the third lecture for the motivation and emotion unit of study.

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
