Receptive field sizes vary considerably across a sensory domain. Speed of adaptation: weights the importance of stimulus changes. Sustained response: neural response to stimulus remains constant as long as a stimulus is present. Transient response: neural response is largest nearest the change in time or space. Receptors make it possible to distinguish self from others (knowing where you stop and the rest of the world begins): Interoceptive: respond to bodily stimuli; help interpret meaning of external stimuli. Optic flow: information carried by changes to the retinal stimulus as we move. Auditory flow: information carried by changes to the auditory stimulus as we move. They may not believe their left hand is their hand and want it removed. They may also only apply makeup to the right side of their face, and never the left.
