Different brain regions are activated when we consider ingroup versus outgroup members. for instance, the is activated when we engage in ingroup bias, but is less active when we consider members of outgroups. a. insula b. nucleus accumbens c. amygdala d. medial prefrontal cortex

D. medial prefrontal cortex

The medial prefrontal cortex is the brain region that shows an increased in activation relevant to in-group levels, which is associated with the level of group identification. However, it is less active in out-group members for it dehumanize other group members. This is the role of medial prefrontal cortex in social categorization particularly to in-group versus out-group members.
