Gazzaniga's experiments
Gazzaniga's experiments, particularly with split-brain patients, involved surgically severing the corpus callosum to study brain lateralization. He showed patients images or words to one hemisphere at a time; for example, presenting a picture to the left visual field (processed by the right hemisphere). Results revealed that each hemisphere has specialized functions and can operate independently. For instance, the left hemisphere excels in language, while the right is better at spatial tasks. These experiments demonstrated how the two hemispheres communicate and revealed the brain’s compartmentalization, deepening our understanding of how consciousness and cognition are distributed across the brain.
