    Psychology -> Hemispheric specialisation Hemispheric specialisation Findings of research of people who have intact brains and those with brain damage Evidence of this hemispheric specialisation has come from cases where people have had brain damage. Brain damage to the left side of the brain, Broca's area, results in problems with the production of speech. Damage to Wernicke's area, found in the temporal lobe of the left hemisphere, usually leads to problems in comprehending language. To further investigate the special abilities of the two cerebral hemispheres, researchers have worked with people who have had a rare type of surgery where their corpus callosum is cut to control severe epilepsy. After the 'split-brain' operation, it is as if the person has two brains. Each hemisphere seems to have its own consciousness, sensations, perceptions and behaviours. Studies of people with intact brains also reveals hemispheric specialisation. When verbal stimuli are presented to the left hemisphere via the right eye or ear, they are processed more quickly and more accurately than when they are presented to the right hemisphere via the left eye or ear. Conversely, the right hemisphere appears to process visual-spatial tasks, such as recognising a face, more quickly.

    each seems to process information at a different speed but give the same results

    the left hemisphere is dominant in some areas as the right processes spatial tasks more quickly?

    Each hemisphere seems to have its own consciousness,sensetions,perceptions and behaviour,-Does this mean the person can experience abrupt non correlated altered consciousness? forgetfulness? non sequential behaviour?

    Base on my personal observation, the left hemisphere is more effective to grab information received via the left ear quick than the ones received through the right hemisphere.

    Where corpus callosum surgery has been carried out does the right side of the brain that previously had a lesser role develop new abilities?

    The surgery to control epilepsy which severs the corpus callosum allows researchers to study hemisphere specialization.
