Document Summary

Theory of equipotential- the brain can do everything: memories are spread over many cortical areas, all cortical areas have the potential to store memories. Evidence for cortical specialization: look at neuronal level, nissl stain: stains nissl bodies, found in body of neuron. Korbinian brodmann: uses nissl staining to subdivide the cortex into areas with different types of cyto-architecture (arrangement of cells, knew little about their function, however, cellular distinctions have functional correlates. Central nervous system: brain and spinal cord. Peripheral nervous system: has two divisions. 2 divisions (work opposite of each other) Sympathetic: prepares the body for action, fight or flight systems . Parasympathetic: system return the body to a resting state, rest and digest . Dividing into front and back: sagittal. Dividing into side and side (l and r) Cerebral cortex: tissue covering the top and sides of the brain, largest structure of the human brain, two hemispheres (left and right, four lobes.
