Split Brain

• Scientists believe the brain is lateralised, meaning the brain is split into two distinct hemispheres
• Hemispheric lateralisation


  The left and right hemispheres process information differently and control different patterns of behaviour
• Corpus callosum


  A network of nerve fibers that connect the two hemispheres, allowing for interhemispheric communication
• In some epileptic patients who are not helped by drug treatment, the corpus callosum is lesioned out to reduce the frequency of seizures
• Although this can help reduce the patients’ seizures, a corpus callosotomy can also affect their behaviour and perception
