Document Summary
Sensory receptors: vision, translates light energy into neural activity/action potentials, critical role in our understanding of the external energy, light energy(cid:224)chemical energy, auditory, air pressure(cid:224)mechanical energy, somatosensory, mechanical energy, activates receptors on the surface of the skin sensitive to touch, pain, etc, taste and olfaction, chemical molecules, certain chemicals fit together on the tongue to communicate messages. Receptive fields: each receptor is looking at one particular part of the world, slightly overlap with other receptors, come together to create a cortical map, allows us to locate sensory events in space, optic flow: information about how we"re moving (or the object around us, moving the pencil to create the illusion that it is rubber. Fine detail vision: to see better in the dark, put more focus on the rods and use peripheral vision; shift eyes slightly, when contrast is important, will determine abilities between species and humans, dogs and scent, etc.
