We measured amygdala activity in human volunteers during rapid visual presentations of
fearful, happy, and neutral faces using functional magnetic resonance imaging (fMRI). The …

We used fMRI to examine amygdala activation in response to fearful facial expressions,
measured over multiple scanning sessions. 15 human subjects underwent three scanning …

Functional magnetic resonance imaging (fMRI) of the human brain was used to study
whether the amygdala is activated in response to emotional stimuli, even in the absence of …

BACKGROUND: Previous functional imaging studies demonstrating amygdala response to
happy facial expressions have all included the presentation of negatively valenced primary …

Despite the many studies highlighting the role of the amygdala in fear perception, few have
examined differences between right and left amygdalar responses. Using functional …

Facial expressions of emotion elicit increased activity in the human amygdala. Such
increases are particularly evident for expressions that convey potential threat to the …

The cognitive and affective systems of the cerebral cortex are often more lateralized in males
than females, but it is unclear whether these differences extend to subcortical systems. We …

The amygdala is a key structure in a limbic circuit involved in the rapid and unconscious
processing of facial emotions. In the present study, the role of the amygdala in automatic …

Most theories of amygdalar function have underscored its role in fear. One broader theory
suggests that neuronal activation of the amygdala in response to fear-related stimuli …

Repeated presentations of emotional facial expressions were used to assess habituation in
the human brain using fMRI. Significant fMRI signal decrement was present in the left …
