Hypothalamus and Limbic System:
Emotion and Motivated Behavior
Emotions and motivated behavior are crucial for
survival:
Emotional responses modulate the autonomic
nervous system to respond to threatening stimuli or
situations.
Emotional responses are adaptive.  If you are
prepared to deal with threatening stimuli, you are
more likely to survive and reproduce.
Motivated behavior underlies feeding, sexual and
other behaviors integral to promoting survival and
reproduction.
The hypothalamus and limbic system mediate these
behaviors.
