Document Summary

Each receptor varies its responses to stimuli that differ quantitatively (changes in the magnitude of a stimulus) or qualitatively (changes in the type of stimulus energy) Sensory adaptation: a change, usually a decrease in sensitivity that occurs when a sensory system is repeatedly stimulated in exactly the sam way, it is the term for what happens to sensation when you fatigue neurons. Neurons in different places signal different qualitative features. How adaptation works: for neurons to use a temporal code means that psychologically important info is coded in the ring rate of neurons. Tuesday november 1st, 2016: when no stimulus is present, nerve cells still re randomly at some spontaneous rate, if a neuron isn"t fatigued, the rate of ring indicates the intensity of a stimulus. From stimulus to brain: most perception is multisensory: relating or involving more than one physiological sense.
