The term inferior parietal cortex refers to a cortical region located primarily in the inferior parietal lobule and surrounding the terminal ascending limb of the lateral fissure. It is lightly myelinated, moderately thick cortex, which includes some areas strongly associated with the task positive network and others with the default network. Like the lateral temporal cortex, it has expanded dramatically in humans relative to macaques and chimpanzees. It includes ten areas: area PGp, area PGs, area PGi, area PFm, area PF, area PFt, area PFop, area IP0, area IP1, and area IP2 ( Glasser-2016 ).
