The Split Brain: Some Thoughts :: Biology Essays Research Papers

The distinguish Brain Some Thoughts Left, practiced, left, proper(ip)--the marching song of the two-mind movement. To hear them talk, youd think that everyone had a second mind, suppressed by the first. That the vocal left disposition dominated the poor artistic right wit. Preventing it from getting a creative persuasion in edgewise. Soon there will be a sentience raising movement Stop referring to the left cerebral hemisphere as the dominant one. Invent a more egalitarian term the like co-chairperson. Co-chairhemisphere? William H. Calvin, Left Brain, Right Brain Science or the New Phrenology. The brain is separated into two hemispheres in your brain, the right and the left. At first view these hemispheres appear to be mirror images of one another, but on contiguous observations the two hemispheres have highly specialized regions that serve differing functions (1). In general, the right hemisphere interprets discipline and controls actions of the left side of the body. T he left hemisphere interprets info and controls actions of the right side of the body. A thick band of fiber called the principal sum callosum connects the two hemispheres. Evidently if the connection between the hemispheres is severed, a once cat valium practice to relieve epileptic attacks, sensory information cannot pass to the prepare region of the brain in order for a corresponding chemical reaction to be made (2). Thus, your brain is SPLIT... To me the disrupt brain theory seemed a bizarre notion. Isnt my brain a whole- controlled by the centrally located minor man who receives my thoughts, processes and multiple functions of my brain? If this is true how could the brain be split into two? Do you have two yous then? The split brain effect was first discovered by Roger Sperry and Ronald Meyers in the early mid-sixties (3). Meyers and Sperry showed that when the cat had its optic chiasm and corpus callosum severed, two independent training centers were established - one in each hemisphere of the cats brain. If the cat had its right eye open and its left eye covered and learned to compel a simple conditioned chemical reaction, it was unable to make the same response when the right eye was covered and the left eye was open. It was as if the discipline was unable to be communicated to the other side of the brain (2) thus, it was obvious that information available to one side remained off-limits to the other.
