Neural projections from the joint to the dorsal root ganglia of the spinal cord 3. The premotor cortex is a crucial part of the brain, which is believed to have direct control over the movements of voluntary muscles. [1] The PMC is about six times larger than the primary motor cortex [2]. The premotor cortex motor area lies anterior to the primary motor cortex. The premotor cortex primarily mainly prepares and executes. The cerebral cortex contains motor areas, sensory areas and large regions (association area) that are neither clearly sensory nor motor in function. These regions called as the association areas are responsible for complex functions like intersensory associations, memory and communication. So, the correct answer is option-d. Sixteen children with hemiparetic CP from 6 to 16 years of age were included to perform a finger tapping task using both non-paretic and paretic hands while the neural activities in the sensorimotor cortex were scanned by fNIRS. Sixteen age-matched healthy children were also measured, as a control group, for a comparative study. The loss of a limb or paralysis resulting from spinal cord injury has devastating consequences on quality of life.

For example, it is well known that neighboring cells in the visual cortex tend to fire to similar stimuli.
The sensorimotor cortices appear to encode several types of movement-related parameters, ranging from muscle activation patterns to body kinematics and or dynamics to name a few [ 15 - 21 ]. During sensorimotor learning, the relationship between neural firing and these parameters can be changed via some form of neuroplasticity.
The sensory cortex is the part of the brain which processes information from the eyes, nose, ears, and skin. It is located just behind the frontal lobe of the brain Here the ascending sensory neurons terminate and the input processed in particular areas,eg. the visual area, the auditory area, the somatosensory area .
