| Abstract: | (CIT): Reid's laboratory studies the general question of how visual information is transformed between the lateral geniculate nucleus of the thalamus (LGN) and layer 4 of the primary visual cortex. LGN cells receive visual input from one eye and are not sensitive to an object's orientation or direction of movement. Cortical cells often receive binocular inputs and are usually orientation and direction selective. In electrophysiological studies, he records the activity of many individual neurons simultaneously in both thalamus and cortex. He finds that the wiring of the direct inputs to cortex is extremely precise. Given the visual properties of any single layer 4 cortical neuron, virtually all of the thalamic neurons that would help it perform this function are directly connected to it. |
