Fifty-four grey and white matter regions correlated with CP ( t > 4.33; FWE < 0.05), including primary motor pathway regions, such as the precentral gyrus, and cerebral peduncle, and regions functionally connected to the primary motor pathway, such as the pallidum, and corpus callosum motor ...
This analysis identified a cluster in the left insular cortex extending into precentral gyrus (1382 voxels, 2 × 2 × 2 mm3, centre of mass Montreal Neurological Institute (MNI) coordinates: x = −42, y = 0, z = 19) (Fig. 3A). The VLSM analysis of set-switching accuracy scores in...
② In the control group, bilateral CST were reconstructed, they originated from precentral gyrus, went downwards to internal capsule, and extended to pontine and medulla oblongata, each fiber had good uniformity in continuous form. In the patients with cerebral infarction, the forms of contralateral...
The corticospinal tract arises from the precentral gyrus (somatomotor area, area 4) and from the postcentral gyrus (areas 3, 1 and 2), ending primarily in laminae VI–IX and in laminae IV and V of the anterior horns of the spinal cord, respectively. Frontal area 6, and parietal areas 5...
