• Hemispheric lateralisation = The idea that each hemisphere (half) of the brain is mainly responsible for certain behaviours, processes and activities
• Sperry and Gazzaniga (1968) conducted split-brain research on 11 epileptic patients. In order to control their seizures, these patients underwent surgical lesioning of the corpus callosum
• one example of hemispheric Iateralisation found by Sperry is that the language appears primarily on the left hemisphere
• Another example is spatial ability, which appears to be primarily on the right hemisphere function
• These findings indicate that the 2 cerebral hemispheres appear to be specialised in different ways
