Brodmann area 40 (BA40) is part of the
lateral fissure, in the inferior lateral part of the parietal lobe
.
It is bounded approximately by the
superior temporal area 22
(Brodmann-1909).
Cytoarchitectonically defined subregions of rostral BA40/the supramarginal gyrus are PF, PFcm, PFm, PFop, and PFt. Area PF is the homologue to macaque area PF, part of the mirror neuron system, and active in humans during imitation.
Function
The supramarginal gyrus part of Brodmann area 40 is the region in the inferior parietal lobe that is involved in reading both as regards meaning and phonology.[1]
