| | THE BRAIN FROM TOP TO BOTTOM |
 | | Broca’s area is generally defined as comprising Brodmann areas 44 and 45, which lie anterior to the premotor cortex in the inferior posterior portion of the frontal lobe. |
 | | Wernicke’s area, of which the temporal planum is a key anatomical component, is located on the superior temporal gyrus, in the superior portion of Brodmann area 22. |
 | | This lobule is composed mainly of two distinct regions: caudally, the angular gyrus (area 39), which itself is bounded by the visual occipital areas (areas 17, 18, and 19), and dorsally, the supramarginal gyrus (area 40) which arches over the end of the lateral sulcus, adjacent to the inferior portion of the somatosensory cortex. |
