Another study in the same direction reported that the structures overlapping DMN (prefrontal medial cortex, ventral anterior cingulate, and precuneus) showed a negative modulation or deactivation to emotional stimuli, which suggests that DMN participates in the monitoring of internal emotional processing .
It was reported that the right amygdala activation had a negative modulation on medial and superior frontal regions, anterior cingulate, inferior parietal, precuneus, and cuneus.
003); this component showed a negative modulation during the fear condition.
This analysis, in which the sensory-motor control condition was included, allowed observing that the negative modulation of IC2 "parahippocampal-prefrontal" included structures involved in emotional face processing.
Another interesting finding was the negative modulation of IC2 which, as mentioned previously, includes regions involved in emotional processing.
IC4 had a positive modulation in the fear condition while IC2 presented a negative modulation to facial stimuli), the coefficients of temporal correlation between the onsets of fear and the time courses of these two components were reviewed.
As a limitation of the present study we refer to the phenomenon of reappraisal of emotional stimuli as a possible mechanism that may be related to the negative modulation of IC2.
