Somatosensory – If the two hemispheres are disconnected, the somatosensory functions of the left and right parts of the body become independent. For example, when something is placed on the left hand of a blindfolded patient with the two hemispheres disconnected, the left hand can pick the correct object within a set of objects but the right ...
Split-brain or callosal syndrome is a type of disconnection syndrome when the corpus callosum connecting the two hemispheres of the brain is severed to some degree. It is an association of symptoms produced by disruption of, or interference with, the connection between the hemispheres of the brain.
When scientists first started observing the alien hand syndrome in split-brain patients, they began to question the nature of consciousness and began to theorize that perhaps when the corpus callosum is cut, consciousness is also split into two separate entities. This development added to the general appeal of split-brain research. [citation ...
The lines represent the voices and the ghostly faces are the hallucinations. The different colors are the different stages, from alert to paranoid state. The chaotic background, along with the lines, represents the confusion from rational and irrational thought, level of stress and anxiety. —Glen Brown.
Essentially, the fissure's purpose is to separate the brain into two hemispheres, left and right. Through case studies of brain damage or stroke to either side of each hemisphere, there is evidence that the left side of the brain controls the right side of the body, and the right side controlling the left side of the body.

Professor Matthew Feldman divided the protesters into three groups: influencers, extremists and people attracted to the ‘carnival-like’ atmosphere.
Research by Michael Gazzaniga and Roger Wolcott Sperry in the 1960s on split-brain patients led to an even greater understanding of functional laterality. Split-brain patients are patients who have undergone corpus callosotomy (usually as a treatment for severe epilepsy), a severing of a large part of the corpus callosum. The corpus callosum ...
