Document Summary

How body turns outside info into electrical signals. Sensation: process by which our sensory systems gather info about environment. Physiological process that underlies transformation of the chemical, mechanical, light, and sound energy in the world into electrical activity in the brain. Process of detecting external events with sense organs and turning the stimuli into neural signals. Perception: selection, organization, and interpretation of sensations as meaningful objects and events. Psychological process involved in the organization and interpretation of sensations. Attending to, organizing, and interpreting stimuli that we sense. Transduction: conversion of physical energy into electrical potentials happens in sensory receptor cells, which are specialized neurons. Each receptor varies its responses to stimuli that differ both quantitatively and qualitatively. When specialized receptors transform the physical energy of the outside world into neural impulses, which travel to the brain and give rise to our internal representation of the world.
