Document Summary
Cognitive neuroscience = study of the physiological basis of cognition. Myelin sheath- insulation, enhances conductivity, communication, new experience (neuro- The motor pathways that help coordination and the number of synapses formed, increase the. Ms can effect the myelin sheath. plasticity) density of the myelin. Light for vision, sound waves translated or transduced into electrical impulses. Light energy > cornea > electrical signal. Taking one thing and translating it into another. The light energy enters your eye through the cornea, the light hits your back of the eye at the back of the retina. Rods see in the dark (light vs dark) Once the light has made it into these receptor cells, they hit the optic nerve it turns into an electrical signal (braid code) Electrode measures electrical current from a single neurone, or adjacent neurones (group) When there is an action potential (electrical impulse), it shows a blip in that signal. Depolarization, default state is a polarized state.
