<prompt> All of the following coical areas contribute fibers to the coicospinal tract, EXCEPT?Primary motor coex precentral gyrusPremotor coexInferior temporal coexPrimary somatosensory coex postcentral gyrus  <response>: 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.
