| Resumo: | In the present study we investigated whether individuals
would take advantage of an extrinsic and incidental
reappraisal strategy by giving them precedent descriptions
to attenuate the emotional impact of unpleasant pictures. In
fact, precedent descriptions have successfully promoted
down-regulation of electrocortical activity and physiological
responses to unpleasant pictures. However, the neuronal
substrate underlying this effect remains unclear. Particularly,
we investigated whether amygdala and insula responses,
brain regions consistently implicated in emotional processing,
would be modulated by this strategy. To achieve this,
highly unpleasant pictures were shown in two contexts in
which a prior description presented them as taken from
movie scenes (fictitious) or real scenes. Results showed that
the fictitious condition was characterized by down-regulation
of amygdala and insula responses. Thus, the present study
provides new evidence on reappraisal strategies to downregulate
emotional reactions and suggest that amygdala and
insula responses to emotional stimuli are adaptive and highly
flexible. |
