| prefrontal cortex | The rostral part of the frontal lobe, bounded by the inferior precentral fissure in humans, which receives projection fibres from the mediodorsal nucleus of the thalamus. The prefrontal cortex receives afferent fibres from numerous structures of the diencephalon, mesencephalon, and limbic system as well as cortical afferents of visual, auditory, and somatic origin.

| prefrontal area | Cortex of the frontal lobe of the cerebral hemisphere, originally, the entire cortical expanse anterior to the central sulcus, including the agranular motor and premotor cortex (Brodmann's areas 4 and 6), the dysgranular cortex (area 8), and the granular frontal (prefrontal) cortex anterior to the latter, now more often refers to the granular frontal (prefrontal) cortex. Synonym: frontal area. (05 Mar 2000) |
| prefrontal leukotomy | Division of one or more nerve tracts in the prefrontal area of the brain for surgical treatment of pain and emotional disorder. Synonym: prefrontal leukotomy. (05 Mar 2000) |

| association cortex | Generic term denoting the large expanses of the cerebral cortex that are not sensory or motor in the customary sense, but are involved in advanced stages of sensory information processing, multisensory integration, or sensorimotor integration. See: cerebral cortex. Synonym: association areas. (05 Mar 2000) |
