Document Summary
How to study: write out your notes and paraphrase, chunk and organize information, study like it"s all sa questions, write out likely exam questions. Interpreting visual information sensed by the eyes. Transduction: change of a physical stimulus into neural energy, applies to all senses. !1: in the eye, transduction takes place in two diff types of cells that are in the retina. Rods - very sensitive to light, bad at color (acuity) Cones - low light sensitivity but better at colours bc 3 different types for different. Visual pathway: images on left and right are seen by both eyes, but each hemisphere only gets the image from it"s opposite side, damage to different parts leads to different types of blindness. Blindsight: patients with damage to occipital cortex are blind (no reaction to light) but when asked to guess where something is, they reach in the correct direction, due to multiple paths existing for visual information.
