hemispheric lateralisation+split-brain research Flashcards
hemispheric lateralisation
idea that 2 hemispheres of the brain are functionally different. certain processes are mainly controlled by 1 hem than the other.
right hemisphere
creativity, emotional context, imagination.
left hemisphere
language, logic, analytic thinking.
corpus callosum
large C shaped nerve fibre bundle found beneath the cerebral cortex. it connects left+right hemisphere.
split brain research- rodger and gazzaniga
11 epileptic patients who had commissurotomy (CC cut off). this was done to control epileptic seizures- removes connection between 2 hem.
split brain research- procedure
image/word was projected to RVF (controlled by LH), and same/diff image was projected to LVF (controlled by RH).
normal brain= CC would share info between hem; clear pic. split brained patients- info could not be conveyed from 1 hem to another.
