Also play different roles in cognitive processing
Hemisphericity
Left Hemisphere
Language (reading, writing) Speech
Calculations (math)
Right Hemisphere
PERCEPTURAL TASKS
Copying drawings
Recognizing faces
Perceiving differences
Perceiving and expressing emotion

Corpus callosum
Corpus Callosum
largest bundle of neural fibers connects the two brain hemispheres carries messages between the hemispheres Roger Sperry & Michael
Gazzaniga
Split Brain

(mainly those of the corpus callosum) between them
Done to reduce epileptic seizures
