Fear, faces, and the human amygdala.
The amygdala's historical role in processing stimuli related to threat and fear is being modified to suggest a role that is broader and more abstract. Amygdala lesions impair the ability to seek out and make use of the eye region of faces, resulting in impaired fear perception. Other studies in rats and humans revive earlier proposals that the amygdala is important not only for fear perception ...
متن کاملFear and the human amygdala.
We have previously reported that bilateral amygdala damage in humans compromises the recognition of fear in facial expressions while leaving intact recognition of face identity (Adolphs et al., 1994). The present study aims at examining questions motivated by this finding. We addressed the possibility that unilateral amygdala damage might be sufficient to impair recognition of emotional express...
متن کاملCultural Specificity in Amygdala Response to Fear Faces
The human amygdala robustly activates to fear faces. Heightened response to fear faces is thought to reflect the amygdala's adaptive function as an early warning mechanism. Although culture shapes several facets of emotional and social experience, including how fear is perceived and expressed to others, very little is known about how culture influences neural responses to fear stimuli. Here we ...
متن کاملThe Human Amygdala and the Induction and Experience of Fear
Although clinical observations suggest that humans with amygdala damage have abnormal fear reactions and a reduced experience of fear, these impressions have not been systematically investigated. To address this gap, we conducted a new study in a rare human patient, SM, who has focal bilateral amygdala lesions. To provoke fear in SM, we exposed her to live snakes and spiders, took her on a tour...
متن کاملHuman amygdala activity during the expression of fear responses.
The initial learning and subsequent behavioral expression of fear are often viewed as independent processes with potentially unique neural substrates. Laboratory animal studies of Pavlovian fear conditioning suggest that the amygdala is important for both forming stimulus associations and for subsequently expressing learned behavioral responses. In the present article, human amygdala activity w...
