What Is the Premotor Cortex?
The primary motor cortex is part of the frontal lobe and is located in Brodmann's area 4. [1] It is mainly responsible for planning, control, motion execution, especially any action related to delayed response. [2]

- The primary motor cortex is part of the frontal lobe and is primarily responsible for planning, controlling, and performing motion, especially any action related to delayed response. If the motor cortex receives electrical stimulation, then a part of the body will move. The key is to see which part of the motor cortex is subjected to electrical stimulation. Control of movement on one side of the body is located on the opposite side of the primary motor cortex (for example, the left body corresponds to the right cortex). A similar reverse mapping occurs from top to bottom, with the upper part of the motor cortex (up to the top of the head) and the lower body as one end of the mapping, and the lower part of the motor cortex and the upper body as the other end of the mapping. [2] The cortical diagram shows the positions and proportions of various parts of the body in the brain. It can be seen from the figure that the more we need sensitivity and precise control over a specific body part, the larger the corresponding cortical area of that part. For example, to communicate with the world, humans need fine hand movements and facial expressions. Correspondingly, there is a large area in the cerebral cortex to handle the feelings of hands and faces and their motor responses. [2]
