Question

Quizplus · Accepted Answer

The cerebral cortex is the outer layer of the brain and is responsible for many complex functions such as language, memory, perception, and consciousness. It contains about 80 percent of the neurons in the brain, which make up the majority of the brain's processing power. The other areas of the brain, including the brain stem, contain important neurons as well, but not to the same extent as the cerebral cortex. Glial cells, while abundant in the brain, do not make up the majority of the neurons. Option D is incorrect, as all neurons in the brain are used to some extent, even if their function is not fully understood.
