What are some behaviors of split-brain patients?
In general, split-brained patients behave in a coordinated, purposeful and consistent manner, despite the independent, parallel, usually different and occasionally conflicting processing of the same information from the environment by the two disconnected hemispheres.
What does split-brain demonstrate?
Split-Brain, Split-Mind Split-brain patients demonstrate that an intact corpus callosum and, correspondingly, interhemispheric communication are not essential for consciousness.
What are the two most common reasons people suffer from split-brain?
Additional and less-common causes of the split-brain syndrome include infectious lesions, ruptured arteries, stroke, tumors, and multiple sclerosis. Rarely, agenesis of the corpus callosum may cause split-brain syndrome.
How does a split-brain individual respond to stimuli?
However, another key element of the traditional view is that split-brain patients can only respond accurately to stimuli in the left visual field with their left hand and to stimuli in the right visual field with their right hand and verbally.
What makes the split-brain patient unique?
Many patients with split-brain syndrome retain intact memory and social skills. Since information cannot be directly shared between the two hemispheres, split-brain patients display unusual behaviours, particularly concerning speech and object recognition.
Do split-brain patients have two minds?
Instead, the researchers behind the study, led by UvA psychologist Yair Pinto, have found strong evidence showing that despite being characterised by little to no communication between the right and left brain hemispheres, split brain does not cause two independent conscious perceivers in one brain.
What makes a split-brain patient unique?
Since information cannot be directly shared between the two hemispheres, split-brain patients display unusual behaviours, particularly concerning speech and object recognition.
How is split brain syndrome treated?
Split-brain surgery, or corpus calloscotomy, is a drastic way of alleviating epileptic seizures, the occurrence of sporadic electrical storms in the brain. The procedure involves severing the corpus callosum, the main bond between the brain’s left and right hemispheres.

Can split brain patients read?
But this is dramatically embodied in a split-brain patient, who may not be able to read aloud a word such as ‘pan’ when it’s presented to the right hemisphere, but can point to the appropriate drawing.
