Explain what Hubel and Wiesel's research on simple cells revealed about ocular dominance.
What will be an ideal response?
Hubel and Wiesel recorded from single cells by penetrating the brain with an electrode. They discovered that some cells had a preference for inputs from either the right or the left eye. This preference is known as ocular dominance, and Hubel and Wiesel discovered that these cells were organized in columns known as ocular dominance columns. Each ocular dominance column comprises neurons that respond to only one eye. The columns alternate between left-eye and right-eye dominance. Hubel and Wiesel also learned that ocular dominance columns combine with orientation columns to form hypercolumns that each correspond to a particular region in visual space.
