Document Summary
Sensory process change over time plays a fundamental role in our later years and decades. Any perceptional experience always arises from an encounter from sources of environmental stimulation. Specialized sensory systems occur due to stimulus (acoustic energy enters our ears stimulating receptors) In general most of us will experience some loss of sensitivity as we age. No other age related loss is as universal as sensory loss. Each sensory system responds to specific forms of energy (and to the information carried by this energy) present in the environment. Energy levels are picked up by specialized receptors and recoded into nerve impulses ( sensory transduction") These nerve impulses are carried by sensory nerves to the brain . Where they are analyzed and interpreted within specialized sensory areas. There are many obvious differences in sensory differences. At the fundamental level all sensory systems share basic features. Sensitive to some sort of energy in the environment.
