| 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) |
| premotor area | A somewhat ill-defined term usually referring to the agranular cortex of Brodmann's area 6. Synonym: premotor area. (05 Mar 2000) |

| pretectal area | A narrow, transversally oriented rostral zone of the mesencephalic tectum, bounded caudally by the superior colliculus, rostrally by the habenular trigone, and laterally by the pulvinar thalami; the area contains several nuclei that receive fibres from the optic tract; it has bilateral efferent connections with the Edinger-Westphal nucleus of the oculomotor nuclear complex by way of which it mediates the pupillary light reflex.
