Figure 1. Limbic cortices in the human brain (modified from [117]).
Cortical limbic areas (in blue) form a ring around the corpus callosum on the medial wall of each hemisphere, continuing along the temporal cortex and the base of the brain [13]. They are neocortical areas that either lack or have a rudimentary layer IV (i.e., are agranular or dysgranular, respectively). They are located between the simpler allocortex and the better-laminated eulaminate cortex. Limbic cortices include the cingulate cortex (subgenual anterior cingulate cortex, sgACC; pregenual anterior cingulate cortex, pgACC; dorsal anterior cingulate cortex, dACC; mid cingulate cortex, MCC; posterior cingulate cortex, PCC), the ventral anterior insula (vAI), the posterior orbitofrontal cortex (POFC), the parahippocampal gyrus (PHG) and the temporal pole (TP).
