Perception

Definitions

Perception is the formation of a holistic image based on certain feelings and sensations.

The outside world exerts influence on nerve endings in the sensory organs (skin, eyes, ears, nose, tongue, muscles). Excitation signals corresponding to tactile, visual, acoustic, olfactory, gustatory, and motive sensations are transmitted to the brain with each receptor sending information about the characteristics of certain actions to the brain. The image of an object or event is recreated in the nervous system based on indications of numerous receptors. As a result of perception we don’t feel a chaotic amount of sensations (splotches of light, sounds, or sensations) but, instead, are able to distinguish objects, people, and events.
