procedure

• many different experiments were conducted, including describe what you see tasks, tactile tests and drawing tasks
• describe what you see- a picture was presented to either the left or right visual field and the participant had to simply describe what they saw
• tactile test- an object was placed in the patient's left or right hand and they had to either describe what they felt, or select a similar object from a series of alternate objects
• drawing tasks- participants were presented with a picture in either their left or right visual field, and they simply had to draw what they saw
• in the 'normal' brain, the Callosum would immediately share the information between both hemispheres giving a complete picture of the visual world
• however, presenting the image to one hemisphere of a split- brain patient meant that information could not be conveyed from that hemisphere to the other
