Neuroanatomical correlates of pleasant and unpleasant emotion

Substantial evidence suggests that a key distinction in the classification of human emotion is that between an appetitive motivational system associated with positive or pleasant emotion and an aversive motivational system associated with negative or unpleasant emotion. To explore the neural substra...

Description
Summary:Substantial evidence suggests that a key distinction in the classification of human emotion is that between an appetitive motivational system associated with positive or pleasant emotion and an aversive motivational system associated with negative or unpleasant emotion. To explore the neural substrates of these two systems, 12 healthy women viewed sets of pictures previously demonstrated to elicit pleasant, unpleasant and neutral emotion, while positron emission tomographic (PET) measurements of regional cerebral blood flow were obtained. Pleasant and unpleasant emotions were each distinguished from neutral emotion conditions by significantly increased cerebral blood flow in the vicinity of the medial prefrontal cortex (Brodmann's area 9), thalamus, hypothalamus and midbrain ( P
