Document Summary
Slide 33- the rods are cleaned up" by the retina. Rods and cones translate light into neural impulses, in which chemical reactions occur that are sensitive to the lights and kick off the signals. Slide 37- even when you focus on a spot between the t and o, your mind seems to explore around. The green sign looked purple, and the blue signs became yellow. That"s because the ganglian might not necessarily fire on/off. When nothing"s happening, the rate of firing shoots normal (resting state), but at different colours (ie. green), the rate slows down. The green looked purple though because the firing rate abruptly slows down in order to accommodate the quick disappearance of the colour overshoots. Both red and green cones are equally stimulated when yellow is seen. The rate of firing will be between fast and slow.
