What triggers the hypothalamus (and other brain
areas) to modulate emotional behavior?
• The control of emotional behavior requires that:
– Emotionally significant stimuli be recognized so as to
trigger specific emotional responses, presumably
through the hypothalamus and other subcortical
pathways.
– Reward information (positive and negative) must in
turn be transferred from the peripheral receptors that
sense reward to cortical and sub-cortical structures
that use this information to guide emotional learning
about stimuli, to remember these stimuli, and to
motivate behavior and emotional responses.
– The limbic system is thought to carry out these
functions and is comprised of a number of
interconnected cortical and subcortical areas.
