AP PSYCHOLOGY

Detailed explanation-1: -The correct answer is A. (motor cortex). Cognitive neural prosthetics are devices that may be surgically implanted to paralyzed people. They register the activity of people‘s motor cortex.

Detailed explanation-2: -Cortical neural prosthetics seek to help paralyzed patients by recording their thoughts directly from the brain and decoding them to control external devices such as computer interfaces, robotic limbs and muscle stimulators.

Detailed explanation-3: -The electrodes are positioned in sensorimotor cortex in the parietal reach region, which is involved in reach planning. The recordings are decoded to obtain the meaning of the cognitive signal and then transformed into processed control signals to operate an external device.

Detailed explanation-4: -Neural prostheses (NPs) are assistive devices that restore functions lost as a result of neural damage. NPs electrically stimulate nerves and are either external or implanted devices. Surface stimulators for muscle exercise are now commonplace in rehabilitation clinics and many homes.

Detailed explanation-5: -The primary function of the motor cortex is to generate signals to direct the movement of the body. It is part of the frontal lobe and is anterior to the central sulcus. It consists of the primary motor cortex, premotor cortex, and the supplementary motor area.
