aggressionviolent offendersFacial expressions robustly activate the amygdala, a brain structure playing a critical role in aggression. Whereas previous studies suggest that amygdala reactivity is related to various measures of impulsive aggression, we here estimate a composite measure of impulsive aggression ...
The amygdala is a small, almond-shaped cluster of neurons located deep in the temporal lobe. It is part of the limbic system and plays a significant role in emotional memory, fear, and aggression. What happens if the amygdala is damaged? Damage to the amygdala may lead to impaired social ...
Along with this efferent fibers, the stria terminalis carries fibers projecting from these three areas back to the amygdala. Stria terminalis plays a major role in various types of organism’s responses tostress. When it leaves the centromedial nucleus, most of its fibers lie between thecaudate ...
The amygdala, sometimes referred to as the amygdaloid body or the amygdaloid complex, is an almond-shaped cluster of nuclei positioned in the limbic system within the medial temporal lobe (Sah et al., 2003; Stephanou et al., 2016). It plays an important role in the transmission of informati...

. And in this vein, it is interesting to note that SM is impaired in her ratings of the degree of arousal present in facial expressions of emotion. Based on these findings, we have suggested that the amygdala may play a role in recognizing highly arousing, unpleasant emotions – in other ...
Left Hemisphere Right hemisphere Function The amygdala is responsible for emotions such as sadness, anger, fear and the controlling of aggression when stimulated. This part of the brain also stores memories from which these feelings have occurred. For example, memories such as dog bite or getting ...
No need to tell us about the role the amygdala or stress hormones play in anxiety, we knew how we were wired. FromWashington Post This may be because of changes in your amygdala, the main area of your brain responsible for emotions like fear. ...
In this study, we developed an automated operant conditioning system to measure social reward in mice and found that adult mice of both sexes display robust reinforcement of social interaction. Through cell-type-specific manipulations, we identified a crucial role for GABAergic neurons in the medial...
In particular, the dMT and its projections to the CeL have been demonstrated to play a role in fear memory retrieval. Notably, the dMT is assumed to be extensively modulated by opioids considering its innervation with opioidergic fibers and the high expression levels of MORs. Previous studies ...
