Unformatted text preview: i. Photoreceptors are at the very back; project to the bipolar cells who protect to retinal ganglian cells (RGCs) which protects to the brain by sending their axons out in a bundle which make up the optic nerve. ii. We also have a layer of horizontal cells which get input from the photoreceptors and then put out to the bipolar cells iii. The Amacrine cells get input from the bipolar cells and put out to the RGCs IV. Concept of Receptive Fields (RFs) Concept: RF is defined as that part of the sensory field that impinges or effects the firing of the neuron we are looking at a. RGC for RF It is arranged in center-surround in the receptive field Retina (picture 2) b. Cells in the Visual Cortex Oriented bar of light equals the best receptive field (Picture 3...
