Speaking The corticobulbar tract originates in the primary motor cortex of the frontal lobe, just superior to the lateral fissure and rostral to the central sulcus in the precentral gyrus (Brodmann area 4). The tract descends through the corona radiata and genu of the internal capsule with a few fibers in the posterior limb of the internal capsule, as it passes from the cortex down to the midbrain. In the midbrain, the internal capsule becomes the cerebral peduncles. The white matter is located in th…
