Document Summary

Thus we have to turn light (electromagnetic radiation) into electricity via transduction in the form of a chemical reaction at the retina. Hearing sounds is mechanical energy; this is also translated into electrical energy: interpretation, visual: illusory contour figure kanisza. Our brain can see a cube when its not really there: hearing: phoneme restoration effect. Experiment with the word legislation and replaced the middle with a cough, individuals still heard the word correctly regardless of the cough being in the middle. The physiology of perception: the neuron and its parts, cell body: contains genetic information, axon: sends information out, dendrites: collect information. The entire system is electrical and communication based and makes up the nervous system: how is information transferred inside a single neuron (pre-synaptic transmission) This is the (cid:271)od(cid:455)(cid:859)s (cid:449)a(cid:455) of prioritizing information. This speed of information sent is dependent on myelin (no myelin slow; myelin fast) and the axon width (thick axon fast; tiny axon slow).
