Abstract:
The limbic system consists of multiple neural circuits, composed of select brain areas and structures that underlie emotion processing and are implicated in many functions throughout the brain, including complex socio–cognitive abilities that are thought to be uniquely human. Here, we review the history of comparative primate limbic neuroanatomy to define and contextualize the limbic system in human evolution. We then identify cortical and subcortical regions and structures that demonstrate significant involvement in emotional processing, and review evidence from the human/nonhuman primate comparative literature that may indicate human-specific specializations of the limbic system.
