A patient, Leo, underwent a corpus callosotomy to treat severe epilepsy. Following the surgery, his doctor notices that when an image of a key is flashed to Leo's left visual field, he is unable to name the object but can successfully select a key from a bag of hidden objects using his left hand.
Explain how Sperry’s (1968) split-brain study helps to explain Leo’s post-operative experiences, and how this relates to the key theme of ‘regions of the brain’.
