Document Summary
Chapter 15: brain asymmetry, spatial cognition, and language. Discovery of language in left hemisphere prompts researchers to consider idea of lateralization. Even though lateralized, halves still communicate with each other so that they may seem the same. Disconnection of the cerebral hemispheres reveals their individual processing specializations o. In cases of epilepsy where medication does not work, cutting of the corpus callosum, the huge axon pathway connecting the two hemispheres, prevents the spread of a seizure from one hemi to other o. Split brain individuals- someone whose corpus callosum has been severed, halting communication between the left and right hemispheres o. Researched split brains, found stimuli could be directed exclusively to one side or other, depending on what side it was sent to determined what could be done with the info. Contralateral-in anatomy, a location on the opposite side of the body. Seeing object with left eye sends to right hemisphere, normally collosum allows for communication b/w.
