What is the name given to the layer of the cerebral cortex due to...

A deep cleft divides the cerebrum longitudinally into two halves, which are called the left and right cerebral hemispheres. The cerebral cortex contains motor areas, sensory areas, and large regions that are neither clearly sensory nor motor in function. These regions, called the association areas, are responsible for complex functions such as intersensory associations, memory and communication.The cerebral cortex contains motor areas, sensory areas, and large regions that are neither clearly sensory nor motor in function.

The left and right cerebral hemispheres are connected by a tract of nerve fibres called the corpus callosum.
