Transduction: to transform physical stimuli in the environment into neural signals in the brain. Example (hearing): sound waves are transformed into vibrations in the ear, and the strength of those vibrations are coded by sensory neurons. 6 major senses: taste, smell, hearing, touch, vision, and pain.
