PSY318H5 Study Guide - Synesthesia, Olfactory Bulb, Proprioception
Document Summary
Portrait: effects of a sensory loss on movement. Lost all fine touch and pressure fibers for the sensory nerves. Diagnosed as having neuropathy- disorder of the peripheral nerves. Proprioception: perception of the position and movement of the body, limbs, and head. Had to learn to replace body awareness with vision http://www. youtube. com/watch?v=fkxyjfe831q. Specialized cells that transduce, or convert, sensory energy into neural activity are energy filters j they respond only to a narrow band of energy within each modality"s energy spectrum. People who lack receptors for parts of the usual visual spectrum are color deficient or color-blind. Transduction of energy: each sensory system is specialized to a different form of energy. Vision: light to chemical energy to action potentials. Audition: air pressure waves to mechanical energy to action potentials. Taste and olfaction: chemical molecules to action potentials. Pain: tissue damage to chemical signal to action potentials. Specific part of the world to which a sensory receptor responds.
