Document Summary

Alzheimers: many neurons stop functioning, lose connections with other neurons, die, affects repair of neurons, disrupts communication in within networks & beyond. Encodes neutral stimuli (dog) events as fearful if you were attacked by a dog. Parkinson"s: striatum isn"t directing behaviour, and substantial nigra and striatum aren"t communicating, also underproduction of dopamine. Highest level of the brain responsible for perception, emotion, movement, and thought. Smooth surfaces are called gyri and fissures are called sulci. It separates the cortex into two hemispheres, plays a role in functions of each hemisphere and specific cortical areas. Connects large areas of the cerebral cortex on each side of the brain. Organization: the occipital lobe: processes visual information, damage: partial or complete blindness. The eyes may work fine but have to use the cerebral cortex to make sense of the information. Parietal lobe: the parietal lobe contains the somatosensory cortex and motor cortex, somatosensory cortex represents the skin areas on other side of body.
