Document Summary
From the retina to the primary visual cortex. The optic nerves join at the base of the brain to form an x-shaped optic chiasm. The axons from the ganglion cells serving the inner half of the retina (nasal sides), cross through the chiasm and ascend to the lgn of the opposite side of the brain. The axons of the ganglion cells serving the outer half of the retina (temporal sides) remain on the same side of the brain. Each hemisphere receives information from the contralateral visual scene/eye. An orientation-sensitive neuron in the striate cortex will respond only when a line of a particular orientation appears within its receptive. If the cell is located in the receptive field and rotated, the cell will only fire if that line is in a particular orientation. Fires the greatest when the neuron is rotated into a horizontal position. Neurons whose receptive field is organized in an opponent fashion.
