L33 Psych 100B Study Guide - Final Guide: Frontal Lobe, Temporal Lobe
Document Summary
Two hemisphere of brain: connected by corpus callosum high density of myelinated axons, contralateral organization. Information received on left goes to right hemisphere (vice versa) Importance of corpus callosum transfer information across hemispheres: specialization. Damage to left hemisphere, near frontal lobe. Damage pattern same as broca"s except damage near temporal lobe. Language is mostly lateralized to the left hemisphere. Hemispheric specialization split brain patients: cut the corpus callosum. Effects very little communication between two hemispheres. What do they look like: how can we test. Present information to one side: present word to left side goes to right hemisphere. Can pick object out by feel with left hand. Right hemisphere important for spatial processing: present compound word (hatband) Hat on the left side goes to right hemisphere. Band on the right side goes to left hemisphere. If ask to say what they saw will say band : present two different messages one to left ear and one to right ear.
