Visual cortex: In 1981, scientists won a Nobel Prize just for discovering how cat brains see simple lines.
A neuron in the visual cortex that responds to a bar-shaped stimulus of a particular orientation. In 1959, David Hubel and Torsten Wiesel first recorded these orientation-sensitive cells in a cat's brain.
