PSYCH 1XX3 Lecture Notes - Lecture 6: Receptive Field, Color Blindness, Two-Streams Hypothesis
Document Summary
Everything in lgn and beyond that opponent. Red-green receptive fields made up of red and green cones. Red green ganglion cells which colour comes first is in the middle. So red in the middle and green surrounds it. These receptive fields project on the ganglion cells. The colour in the centre is the excitatory activates the cones exciting means increasing the firing rate. If green light shone on it it inhibits signal sent even more slowly. Excitatory bipolar cells send signals to red green ganglion cells. The opposite process for green-red ganglion cells green is the excitatory one here. All the receptive fields overlap saying the same thing. If blue light shone on the receptive field nothing happens. If yellow light shone on red green receptive field red and green both respond red excites bipolar cells green will send inhibitory signal to bipolar cells end at the base line so no signal.
