Document Summary
Functional spacialization: specialization of different neural pathways and different areas of the brain for representing different kinds of information. Retinotopic mapping: an arrangement of neurons in the visual system whereby signals from. Rgcs with receptive fields that are next to each other on the retina travel to neurons that are next to each other in each visual area of the brain. Rgcs emerge from the back of each eye to form the optic nerve. Left and right optic nerves travel only a few cms until they reach the optic chiasm. Optic chiasm: area where the optic nerve from each eye splits in half. Optic tract: continuation of the optic nerve past the optic chiasm. Contralateral organization: opposite-side organization, in which stimulation of neurons on one side of the sensory organ is represented by the activity of the brain. Part of the thalamus; receives visual signals via the axons of rgcs.
