NEUR 2600 Lecture Notes - Lateral Geniculate Nucleus, Two-Streams Hypothesis, Visual Cortex
Document Summary
Whole dorsal part of the brain is unconscious. Cross half the fibers from each eye to each side. Only excite a small part of the retina, which will only excite a small part of the visual cortex. The visual field for the bunny is just the area of the right visual field. Find what it responds to, must find what its visual field is. Visual field projects onto a visual map, and so has a topographic representation. A stroke in a right visual cortex produces a blind spot in the left visual field. If below the clacarine fissure, the blind spot is in the upper quadrant. The ventral stream but not the dorsal stream functions under anesthesia. Inhibition and excitation - the two response modes of neurons. Cells went on to spots of light or off or both. If you put a light in the centre of the screen and indicate when the cell discharged.
