What's that? What's it do?

Today we'll be learning about the corpus callosum! yay!

The corpus callosum (Latin: tough body), also known as the colossal commissure, is a wide, flat bundle of neural fibers beneath the cortex in the brain at the longitudinal fissure. It connects the left and right cerebral hemispheres and facilitates interhemispheric communication. It is the largest white matter structure in the brain, consisting of 200–250 million contralateral axonal projections.

The cool thing about the corpus callosum is that it controls all communication between the two sides of your brain. So, if this did not exist or was completely damaged/severed you would have a lot of difficulty clapping as the coordination between the two sides of your body wouldn't be possible.

What's that? What's it do?

This is the first in a series that will pick a single part of the brain and explain its function. As the first I will pick the most obvious one, THE CEREBRUM!

The cerebrum is not the brain itself, although the word comes from the latin "the brain" or "the understanding", but is the largest part of the brain. It has two cerebral hemispheres that are constituted of: cerebral cortices, basal nuclei, and the limbic system. Together, with your cerebellum, it coordinates and executes every conscious task you ever do.

It is easily one of the most important structures, not just in your brain, but in your body.
