Document Summary
In acallosal adult patients (do not have a corpus callosum), they have language on both sides of their brain regardless of handedness. In children with early, extensive brain damage, they have language on the opposite hemisphere of the brain with damage; these children can recover very well and still develop speech. Another technique that is used is to make a patient look straight ahead at a slide, measure reaction time and ask what you saw (slides are split in half with two different images) Split-brain patients seem fine in everyday life; gazzaniga and sperry were the first people who decided to study these people and understand the whole idea of right/left brain patients and what they do. A) an object is presented to the right hemisphere visually- 1. Can be picked out by the left hand. B) the word is spelled out and presented to the right hemisphere- 1. Cannot tell you what it is verbally 2.
