PSY290H5 Lecture Notes - Lecture 6: Sensory Cortex, Posterior Parietal Cortex, Isotope Fractionation
Document Summary
The variety of eyes: all animals have sensory organs containing receptor cells that sense some stimuli but not others, sensory organs are very diverse but all senses use the same type of energy - action potentials. How do we see color: cool thing about our eyes is what we can and can"t see, the pallet our eyes are working with is actually pretty limited. Sometimes, we need receptors to be quiet: adaptation - the progressive loss of receptor sensitivity as stimulation is maintained, d. Slow adapting receptors: take a little longer to adapt, good for things like holding cups, in order to know how to hold it. Functional sense: don"t always want to be aware of everything in the env, what do sensory receptors have in common, respond over a huge range of intensities, how, what do sensory receptors have in common, range fractionations.
