Document Summary

Chapter three biological psychology: the brain o cerebral cortex. Gray matter: forms a continuous cortical sheath composed of clusters of cell bodies, have dark gray appearance from cell body structures. White matter: composed of axon bundles, is white because of the myelin sheaths (white fatty tissue) that covers the axons o left and right hemispheres connected by fibers called. Corpus callosum: largest bundle of fibers, connects two brain hemispheres, carries messages between the two hemispheres. Temporal hearing, language, object & face recognition. Found that stimulating regions of the motor cortex triggers movement in different parts of the body. All 600 muscles of the body are represented in the motor cortex. Developed a map of the motor cortex, called motor homunculus o language processing: Broca"s area: in left hemisphere, directing muscle movement in order for you to speak. Wernicke"s area: left hemisphere, involved in language comprehension o visual fields: Both eyes send information to both hemispheres.
