Document Summary
Brain damage effects: if one hemisphere is damaged early in life, other will assume many functions by reorganizing or building new pathways, plasticity diminishes later in life, brian sometimes mends itself by forming new neurons through neurogenesis. Brain damage studies revealed many functions of the left hemisphere. Brain scans and split brain studies show more about the functions of the two hemispheres and how they coordinate with each other. Sensation: bottom-up process by which the physical sensory system receive stimuli at the. Perception: mental process of organizing and interpreting that sensory input from very basic level of sensory receptors and works up experience and expectations. Bottom-up processing: sensory analysis that begins at the entry level, with information flowing from the sensory receptors is the brain. Top-down processing: info processing guided by high-level mental processes, as when we construct perceptions by filtering information through our experience and expectations.
