Where is the cortical brain?
The cerebral cortex is a sheet of neural tissue that is outermost to the cerebrum of the mammalian brain. It has up to six layers of nerve cells. The cortex is gray because nerves in this area lack the insulation (myelin) that makes most other parts of the brain appear to be white.

What are cortical areas?
Functional Divisions of the Cerebral Cortex
| Cortical Area | Function |
|---|---|
| Prefrontal Cortex | Problem Solving, Emotion, Complex Thought |
| Motor Association Cortex | Coordination of complex movement |
| Primary Motor Cortex | Initiation of voluntary movement |
| Primary Somatosensory Cortex | Receives tactile information from the body |
What are the cortical and subcortical areas of the brain?
In humans, the cortex is where many of the higher-level functions take place (e.g. decision-making and language). ‘Subcortex’ means ‘beneath the cortex’. The subcortex is where we process more primitive functions (e.g. emotion processed in the amygdala).
What is cortical function in the brain?
Cerebral Cortex Lobe Functions. The cerebral cortex, which is the outer surface of the brain, is associated with higher level processes such as consciousness, thought, emotion, reasoning, language, and memory.
What are the brain hemispheres?
The right hemisphere controls the muscles on the left side of the body, and the left hemisphere controls the muscles on the right side of the body. Enlarge. Anatomy of the brain, showing the cerebrum, cerebellum, brain stem, and other parts of the brain.
What are cortical neurons?
Cortical neurons can be broadly divided into two classes: interneurons and projection neurons. The interneurons are a varied subgroup of cells, which occupy many different cortical layers and largely utilize GABA as a neurotransmitter. These neurons migrate radially from the germinal zones into the cortical plate.
Where in the brain are the sensory areas located?
parietal lobe
The primary somatosensory cortex is located in a ridge of cortex called the postcentral gyrus, which is found in the parietal lobe. It is situated just posterior to the central sulcus, a prominent fissure that runs down the side of the cerebral cortex.
Is frontal lobe cortical or subcortical?
The frontal lobe is covered by the frontal cortex. The frontal cortex includes the premotor cortex, and the primary motor cortex – parts of the motor cortex. The front part of the frontal cortex is covered by the prefrontal cortex. There are four principal gyri in the frontal lobe.
Is the temporal lobe cortical or subcortical?
The temporal lobe contains much subcortical white matter, with such named bundles as the anterior commissure, arcuate fasciculus, inferior longitudinal fasciculus and uncinate fasciculus, and Meyer’s loop of the geniculocalcarine tract.
Which part of the brain connects the two hemispheres?
the corpus callosum
The two hemispheres are connected by a thick band of nerve fibres called the corpus callosum. The brain halves are able to communicate with each other via this ‘bridge’.
What is a brain structure?
The brain has three main parts: the cerebrum, cerebellum and brainstem. Cerebrum: is the largest part of the brain and is composed of right and left hemispheres. Cerebellum: is located under the cerebrum. Its function is to coordinate muscle movements, maintain posture, and balance.
