The cerebral cortex (cortex cerebri) is the outer layer of our brain that has a wrinkled appearance . It is divided into fields with specific functions such as sight, hearing, smell, and sensation, and controls higher functions such as speech, thinking, and memory.
What is the cerebral cortex and what is its function?
The cerebrum is composed of two hemispheres. The cerebral cortex is composed of four lobes: frontal lobe, parietal lobe, temporal lobe, and occipital lobe. The major function of the cerebrum is to control the voluntary muscular movements of the body . The cerebral cortex is mainly involved in the consciousness.

What does the cerebral cortex do quizlet?
The coiled outer layer of the brain’s cerebral hemispheres that is involved with information-processing activities such as perception, language, learning, memory, thinking, and problem solving, as well as the planning and control of voluntary bodily movements.
Where is the visual cortex located in the brain?
The primary visual cortex is found in the occipital lobe in both cerebral hemispheres.
Which lobe is the sensory cortex in?
This cortex is located within the which is located in the postcentral gyrus of the parietal lobe , and lies behind the primary motor cortex of the frontal lobe. The somatosensory cortex receives tactile information from the body, including sensations such as touch, pressure, temperature, and pain.
What is the difference between neocortex and cerebral cortex?
Neocortex refers to a part of the cerebral cortex concerned with sight and hearing in mammals, regarded as the most recently evolved part of the cortex while cerebral cortex refers to the outer layer of the cerebrum composed of folded grey matter and playing an important role in consciousness.

What is cerebral cortex white or gray matter?
Cerebral cortex – The outer layer of the brain, the cerebral cortex, consists of columns of gray matter neurons, with white matter located underneath . This area is essential to many facets of higher learning, including attention, memory, and thought.
