Dorsomedial prefrontal cortex

The dorsomedial prefrontal cortex (dmPFC or DMPFC) is a section of the prefrontal cortex in some species' brain anatomy. It includes portions of Brodmann areas BA8, BA9, BA10, BA24 and BA32, although some authors identify it specifically with BA8 and BA9 Some notable sub-components include the dorsal anterior cingulate cortex (BA24 and BA32), the prelimbic cortex, and the infralimbic cortex.

In humans, the dmPFC is involved in creating a sense of the self. This sense of self that the dmPFC is involved in is what Édouard Claparède referred to as 'me-ness'. It is also involved in what is called 'Theory of mind', or consideration of the mental states of others. Brain activity in the dmPFC has been shown to be significant in altruism. Conversely, this region has been shown to be unusually inactive in people exhibiting psychological dissociation. The dmPFC also modulates or regulates emotional responses and heart rate in situations of fear or stress, and plays a role in long-term memory. The DMPFC can also be identified in monkeys. The prelimbic system in mice is believed to be functionally analogous to the dmPFC's emotional regulation function in humans.
