Emotion and reward
Emotional experience, and the ability to reflect upon our
emotions, forms an integral part of our lives, guiding our
actions and enriching our sense of satisfaction.
Rewards, both good and bad, play an integral role in
modulating emotions and motivated behavior.
As we shall see, emotions are mediated by the limbic
system, which includes the hypothalamus.  The limbic
system is a complex set of interconnected brain areas
that integrate information about sensory stimuli,
memories, and cognitive plans to produce emotional
learning and emotional experience.
