Also propose that the primary motor cortex cause more changes in the motor areas during the motor execution (ME) than in the MI due to interaction with supplementary motor area [15-17].
In contrast, there are also studies showing that activation of cortical motor areas that have somatotopic organization with action-related language does not follow somatotopic organization (6).

During the active task performed at postinterventions with the affected foot, the SMC, the SMA, the cerebellum, cingulate motor area, and the supramarginal gyrus contralateral and ipsilateral to the movement were activated (Figure 2(b) and Table 3).
On the other hand, a small percentage of patients with a deep lesion including the basal ganglia without frontal cortical damage were reported to exhibit a positive palmar grasp reflex [14], and the extension of a supplementary motor area (SMA) lesion into more lateral regions of area 6 may increase the strength of the grasp reflex [15].
