The vertebrate brain is formed by 2 cerebral hemispheres that are separated by a groove, the medical longitudinal fissure. The brain can be described as being divided into left and right cerebral hemispheres. These hemispheres have an outer layer of grey matter, the cerebral cortex, that is supported by an inner layer of white matter.
My brain results for the brain indicator test were a 4.5. The traits i feel particularly strongly about myself are, i'm more of the right side of my brain then my left.
