Handling the Brain Essay -- Biology Essays Research Papers

Handling the idea The initial premise of this web search was to tempt what differences, if any, were known to exist in the headway of the ambidextrous individual. An actual categorisation of ambidexterity seems to have been all simply eliminated, while the explanation of the term, laterality, has be sleep with increasingly muddled. Beyond superstitions and mysticism, in its earliest history an individuals secernment of the left or right hand proved significant mainly to those clinicians who utilized this physical clue of handedness as an indicator of brain lateralization (2). Lateralization in general refers to the concept that a given function is controlled preferentially by one side of the brain or body (5). Brain lateralization further implicates the available specialization of the twain cerebral hemispheres - the left and right - which may be distinct in the localization of neural mechanisms for particular functions (3). The corpus callosum serves as the physical and fu nctional connection between these two cerebral hemispheres. Each hemisphere receives sensory(prenominal) information and controls movement on the side of the body opposite its location. An inherent corpus callosum insures communication between the two hemispheres to build a panoptic understanding of actions and perception. In certain extreme cases of severe epileptic seizures a split-brain operation is necessary, severing the corpus callosum, which serves to greatly reduce seizure frequence but leaves the cerebral hemispheres to function virtually independently (6). Handedness then, has come to be considered - not merely the hand you favor for writing - but rather a possible indication of hemispheric language specialization. It was the french neurosurgeon, capital of Minnesota... ...
