Here we provide a review of the animal and human literature concerning the role of the
amygdala in fear conditioning, considering its potential influence over autonomic and …

Recent studies have begun to elucidate the roles played in social cognition by specific
neural structures, genes, and neurotransmitter systems. Cortical regions in the temporal lobe …

We used positron emission tomography to study neural mechanisms underlying intensely
pleasant emotional responses to music. Cerebral blood flow changes were measured in …

▪ Abstract Learning the relationships between aversive events and the environmental stimuli
that predict such events is essential to the survival of organisms throughout the animal …

We used event-related fMRI to assess whether brain responses to fearful versus neutral
faces are modulated by spatial attention. Subjects performed a demanding matching task for …

The brain circuitry processing rewarding and aversive stimuli is hypothesized to be at the
core of motivated behavior. In this study, discrete categories of beautiful faces are shown to …

Neural responses accompanying anticipation and experience of monetary gains and losses
were monitored by functional magnetic resonance imaging. Trials comprised an initial" …

We performed successive H215O-PET scans on volunteers as they ate chocolate to beyond
satiety. Thus, the sensory stimulus and act (eating) were held constant while the reward …

Background: The amygdala has a central role in processing emotions, particularly fear.
During functional magnetic resonance imaging (fMRI) amygdala activation has been …

Neuroimaging technology has provided unprecedented opportunities for elucidating the
anatomical correlates of major depression. The knowledge gained from imaging research …
