Document Summary
Nature vs. nurture and how we come to experience our worlds. It"s not as simple as nature being separate from nurture. Epigenetics- not actual genes but the expression of genes. High levels of exercise, turns on gene (miracle grow gene), helps create synapses in brain. Altering communication system of brain, and the way you engage and think about the world (cycle) Nerves are firing (communicating together) and then wiring together. Sensation- straightforward mechanical process; physical stimulus and sensory. Transduction- translation, physical conversion into chemical and electrical signals. Perception- interpretation, organization, and integration process; during this receptors that receive them; lightwaves being detected that brain can understand process the brain makes sense of physical stimuli. Lightwaves come into eye- physical stimulus- rods (low light conditions, don"t help you see detail) and cones (allow you to see color, bright light conditions, see detail) detect (sensation) Thalamus- decides where rest of information goes > occipital lobe (processing.
