Define sensation

detecting physical energy with our sense organs (eyes

Define perception

the brain's interpretation of the raw sensory information

Define illusion

way we perceive a stimulus doesn't match its physical reality

Define transduction

conversion of an external stimulus into a neural signal

Define sensory receptors

specialized ells designed to convert a certain kind of external information into a neural signal

Define sensory adaptation

sensory neurons adjust their sensitivity based on recent stimulus history

Define aftereffects

are opposing sensory or perceptual distortions that occur after adaptation
