The motor cortex is the region of the cerebral cortex involved in the planning, control, and execution of voluntary movements. The motor cortex is an area of the frontal lobe located in the posterior precentral gyrus immediately anterior to the central sulcus. Motor cortex controls different muscle groups
The parallel CBGTC loops have been segregated according to the functions of associated cortical regions. One scheme involves the division into limbic and motor loops, with the motor loops containing indirect and direct pathways, which are in turn interconnected with the limbic loop that projects into the ventral striatum.

The cerebellar cortex projects to the deep cerebellar nuclei (the corticonuclear microcomplex). The deep nuclei then project to the thalamus, which in turn projects back to the cerebral cortex. [5] This cerebrocerebellar circuit is key to understanding the motor as well as the non-motor roles of the cerebellum.
Primary motor cortex is defined anatomically as the region of cortex that contains large neurons known as Betz cells, which, along with other cortical neurons, send long axons down the spinal cord to synapse onto the interneuron circuitry of the spinal cord and also directly onto the alpha motor neurons in the spinal cord which connect to the ...
The neurocircuitry that underlies executive function processes and emotional and motivational processes are known to be distinct in the brain. However, there are brain regions that show overlap in function between the two cognitive systems. Brain regions that exist in both systems are interesting mainly for studies on how one system affects the ...
Thalamus – The thalamus is involved in combining sensory and motor signals and then sending that information to the cerebral cortex. [12] The thalamus plays an important role in regulating sleep and wakefulness. [13] Hypothalamus – The hypothalamus is involved in producing a physical response (for example, crying) with an emotion.
The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain and spinal cord.The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric and triploblastic animals—that is, all multicellular animals except sponges and diploblasts.
Central structures include cerebral cortex, brainstem, spinal cord, pyramidal system including the upper motor neurons, extrapyramidal system, cerebellum, and the lower motor neurons in the brainstem and the spinal cord. [3] The motor system is a biological system with close ties to the muscular system and the circulatory system.
