Document Summary
If severed split brain syndrome effectively having 2 independently operating hemispheres. Normal patients sensory and motor info crosses over from one side of the brain through thalamus this info also available on the same side or ipsilateral hemispheres by travelling through corpus callosum. Split brain syndrome once info arrives on the contralateral side (opposite) of the brain it is trapped there and unable to travel to the other hemisphere. Patients relatively unaffected because stimuli perceived bilaterally. Patient stares at a fixation point ahead. Then presented a picture of a cup to the left visual field. Visual stimuli are organized into visual fields and not by eyes. Image of the cup travels directly to the right hemisphere of the brain only. If ask to name the object that she saw she will be unable to name it because language preferentially processed by left hemisphere.
