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

The Split Brain Some Thoughts Left, discipline, go away hand, right--the marching yell of the cardinal-mind movement. To hear them talk, youd think that every star had a second mind, suppressed by the first. That the strain left brain dominated the poor artistic right brain. Preventing it from get a creative thought in edgewise. Soon there go out be a consciousness raising movement Stop referring to the left cerebral hemisphere as the dominant one. Invent a more(prenominal) egalitarian term like co-chairperson. Co-chairhemisphere? William H. Calvin, Left Brain, Right Brain experience or the New Phrenology. The brain is separated into two hemispheres in your brain, the right and the left. At first glance these hemispheres appear to be mirror images of one another, but on closer observations the two hemispheres have highly specialise regions that serve differing functions (1). In general, the right hemisphere interprets information and controls actions of the left location of the body. The left hemisphere interprets information and controls actions of the right place of the body. A compact band of fiber called the school principal callosum connects the two hemispheres. Evidently if the connection amidst the hemispheres is severed, a once common practice to relieve epileptic attacks, sensational information cannot pass to the correct region of the brain in stray for a corresponding response to be made (2). Thus, your brain is SPLIT... To me the expose brain theory seemed a bizarre notion. Isnt my brain a whole- controlled by the centrally located little man who receives my thoughts, processes and multiple functions of my brain? If this is uncoiled 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 M fondnessrs in the early 1960s (3). Meyers and Sperry showed that when the cat had its optic chiasm and corpus callosum severed, two independent learning centers we re established - one in distributively hemisphere of the cats brain. If the cat had its right eye open and its left eye covered and learned to make a simple conditioned response, it was uneffective to make the same response when the right eye was covered and the left eye was open. It was as if the learning was unable to be communicated to the other side of the brain (2) thus, it was obvious that information available to one side remained out-of-bounds(predicate) to the other.
