All of the following coical areas contribute fibers to the coicospinal tract, EXCEPT?
Coicospinal and coicobulbar tract neurons are pyramidal shaped and located in layer V of the cerebral coex. About 31% of the coicospinal tract neurons are from the primary motor coex. The premotor coex and supplementary motor coex account for 29% of the coicospinal tract neurons. The other 40% of coicospinal tract neurons originate in the parietal lobe and primary somatosensory area in the postcentral gyrus. The inferior or ventral temporal coex does not contribute fibers to the coicospinal tract.
Primary motor coex (precentral gyrus)
Premotor coex
Inferior temporal coex
