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.


  1. glad my corpus callosum is working. i love to clap.

  2. not to mention walking would be difficult, eh?
