Quizplus · Accepted Answer

The description given in the question is that of the cerebral cortex, which is a thin layer of gray matter on the surface of the cerebral hemispheres that is responsible for higher mental functions, general movement, perception, and behavioral reactions. Therefore, the correct choice is A) Cerebral cortex. The brainstem is responsible for basic vital functions such as breathing and heart rate. The amygdala is responsible for emotions and motivation, and the basal ganglia are responsible for motor control and learning. However, none of these structures match the description given in the question as closely as the cerebral cortex.
