Keeping this in view, what is the function of the motor cortex in the brain?
The primary motor cortex, or M1, is one of the principal brain areas involved in motor function. M1 is located in the frontal lobe of the brain, along a bump called the precentral gyrus (figure 1a). The role of the primary motor cortex is to generate neural impulses that control the execution of movement.
Also, what does the motor cortex consist of? The motor cortex comprises three different areas of the frontal lobe, immediately anterior to the central sulcus. These areas are the primary motor cortex (Brodmann's area 4), the premotor cortex, and the supplementary motor area (Figure 3.1).
Also to know is, what part of the brain is the motor cortex?
One of the brain areas most involved in controlling these voluntary movements is the motor cortex. The motor cortex is located in the rear portion of the frontal lobe, just before the central sulcus (furrow) that separates the frontal lobe from the parietal lobe.
What happens if the motor cortex is damaged?
The motor system and primary motor cortex The brain's motor system is contained mostly in the frontal lobes. If someone suffers a stroke, for instance, that causes damage to the primary motor cortex on one side of their brain, they will develop an impaired ability to move on the opposite side of their body.
