Hemispheric Lateralisation - Outline

What is Hemispheric Lateralisation
The fact that two halves (hemispheres)of the brain are not identical - each have specialised components limited to them
1 of 7
Research has found that....
Functions e.g. language and speech have been found to be localised in the left hemisphere
2 of 7
Split- Brain research has shown....
The brain is not split into specific sections while deal with specific tasks, but instead the way the brain is connected between different regions is just as important as the function of the different regions of the brain
3 of 7
Paul Broca (Left hemisphere)
Able to verify this difference between hemispheres as found damage to left area where language and speech centres are -> problems in such areas
4 of 7
Paul Broca (Right hemisphere)
The same damage on the right hemisphere with the same area did not result in language or speech problems.
5 of 7
Communication between the two hemispheres
Able to communicate as they are both connected. This allows information received by one to be shared with the other through nerve fibres known as the corpus callosum
6 of 7
Split-Brain Research and Findings (Sperry and Gazzaniga, 1967)
Able to study HL and capabilities of each hemisphere by sending visual info to one hemisphere. Found when corpus callosum cut, info presented to one hemisphere can only be processed by that one - can't share info
