Split-Brain Patients

The corpus callosum is the bundle of never fibers that connect the two hemispheres of the brain. It’s the largest single structure in the brain, with some two hundred million fibers. As a last resort for epilepsy, this bundle can be cut in a procedure known as a callostomy. When this happens, a split-brain patient … Continue reading Split-Brain Patients

Somatophrenia

Look at the right side of your body. It’s yours, right? Or maybe it’s your neighbor’s… Somatoparaphrenia is caused by damage to the right parietal lobe. The similarity of this disorder to BIID, coupled with the childhood onset of these disorders, suggest both may be congenital disorders, that is, present from birth. The disorder is a … Continue reading Somatophrenia

Myelin

We know that neurons are encapsulated by myelin. But what makes the myelin? The brain contains two major classes of cells: neurons and glia. Glia are responsible for creating the myelin sheath, as well as having many other functions. There are different kinds of glia, including Schwann cells, oligodendrocytes, astroctytes, microglia, and more. The Schwann cells … Continue reading Myelin
