Document Summary

Respond to physical energy and convert it into language for nervous system (nervous system only understands ions) Highly selective for types/ subtypes of energy. Certain receptors only respond to certain types of energy. Sensitive to adequate stimulus (stimulus they are selective for) Ex: rods and cons for vision; each system has their own type of receptor. Transducer-- converter; movement of ions across membranes. Part of pns and cns that mediate the sensory modality. No matter how or where neural structures are activated, the sensation will be appropriate for that system. Ex: if visual cortex is stimulated, person will see something. No matter where neural structures are activated, the sensation will appear to originate in the world (periphery) Ex: if visual cortex is stimulated, person will see something in the actual world- not in their head. People report sensations coming from amputated limbs. Feel things in part of body that they don"t have anymore.
