a limitation of split brain research comes from danelli
danelli studied patient EB who had their left hemisphere removed at a young age
after rehabilitation, EB was able to recover their language skills
which wouldnt have been possible is language skills were lateralised to the left hemisphere
danelli conducted the case study through verbal testing and MRI to compare images of their brain with that of people with typical brains
found that hemispherically lateralised functions can be taken over by the right
