GN 009 motorische Reizleitung / motor cortex

Das Gehirn sendet Signale über die motorischen Nervenbahnen zu den ausführenden Organen. So many different structures in the brain are involved in motor functions that some people even say that practically the entire brain contributes to body movements. The information from the frontal, prefrontal, and parietal areas of the cortex passes through the basal ganglia, then returns to the supplementary motor area via the thalamus. The basal ganglia are thus thought to facilitate movement by channelling information from various regions of the cortex to the SMA. The basal ganglia may also act as a filter, blocking the execution of movements that are unsuited to the situation.
