Is a collections of 250 to 800 million neural fibers that connect the left and right hemispheres of the brain, permitting them to communicate and coordinate processing

Corpus callosum

Explanation:

Corpus callosum is the red part of the brain that has a “C” shape. The corpus callosum, which is made up of over 200 million of neural fibers, links both hemispheres of the brain (the left and right brain) together, which allows for coordination and complex communication between both in order for the brain to function properly.

This structure usually starts forming about 12 weeks after conception of a child, and continues to develop up to about 12 years of age of the child.  

The main function of the corpus callosum is the ensuring of uninterrupted flow of information, and the integration of complex information and tasks such as motor, sensory and cognitive functions between both hemispheres of the brain.
