The Contribution of Split-Brain Studies to Our Understanding of Brain F
Understanding brain operation has been a complex phenomena in the vault of heaven of Biopsychology yielding mountains of research, speculation and differing opinions amongst researchers. Obvious is that, which our brains are comprised up from dickens hemispheres, the safe and the left (in Gazzaniga., 2002). With great scrutiny research has successfully demonstrated that the ii hemispheres are highly specialized regions serving differing functions a concept referred to as lateralization of function (in Passer, Smith, Holt, Bremner, Sutherland & Vliek 2009). For example, the left hemisphere is responsible for speech production whilst the even up on hemisphere deals with the comprehension of emotional responses. It is also the case that the right hemisphere governs the left side of the body and the left hemisphere governs the right side of the body with the brain displaying contralateral control (in Passer et al., 2009). A common misconception exhibited by most is that the brai n acts as a whole, kind of the brain is performs on a unitary level with independent functions (in Pinel., 2009). Because the cardinal cerebral hemispheres are known to communicate via the corpus callosum(in Pinel., 2009) researchers have been especially intrigued with the idea of what happens when the confabulation between these hemispheres are disrupted. The corpus callosum is a nosepiece of nerve tissues in the brain which acts as a communication animal foot (in Pinel., 2009). Damage to the corpus callosum results in a fall apart brain, a bureau where the neural connections in the brain are severed resulting in disconnected mental abilities. The consequences of these lost mental abilities can be demonstrated done a large number of split brain studies with the help two prominent researchers... ...e that the brain serves many different purposes rather than being a unit of its own and that hemispheric differences exist in the brain. With or without communication through th e corpus callsoum, the two cerebal hemispheres are perfectly capable of functioning in an independent manner.Research aimed to understand the biological basis of hemispheric function has somewhat reached general consensus. However, individual variations must be acknowledge in split brain patients as cognitive abilities vary significantly. References Gazzaniga, M. S. (2002).
