Document Summary

But if u have something relevant to say for a couple sentences, won"t be penalized. *parts of body that process incoming + outgoing information. Incoming = sensory; outgoing = peripheral ns (movement) The sense we rely on most (vision) is least developed in infancy! (b/c no prenatal exposure to it; if ur not exposed to particular sensation ur not going to develop it) The 2nd sense we rely on most = hearing. *good experiment on exposure of sensory system 1 group deny sensory info; 2nd group give the sensory info = can"t conduct on humans; can conduct on animals. Blinded cats during development (infancy), and cats remain blind (can"t see) Transduction = physical energy to neural signal (transducing 5 senses into a neural signal) 1. 1000 m wavelength = radio wave (or ac/dc) (can"t harm people) *visible band is between the infrared and ultraviolet. @ high end of visible band = red is color detectable.
