Document Summary

Neuroscience incorporates: anatomy, physiology, psychology, pharmacology, and computational. Concerned with conscious perception of touch, pressure, pain, temperature, position, movement, and vibration, which arise from muscles, joints, and skin. Proprioception: the sixth sense (sensation of where your body parts are) Refers to the sense by which contact by the body is perceived consciously. What we want to know alters how we interact with an object. You i(cid:374)teract (cid:449)ith the (cid:449)orld, it"s (cid:374)ot just se(cid:374)satio(cid:374), it"s (cid:373)otor. How you move and interact changes based on what you want to know. Sense of relative position/motion of neighbouring body parts and effort being employed: position sense: static body geometry, kinesthesia: sense of motion, sense of effort: sense of when we do things, something is hard, heavy, light. Two point discrimination: do you have normal perception of where the skin is contacted. Position sense: move a finger up and down, do you know which way it moves.
