Summary
We want to understand how neuronal circuits give rise to vision. We can use microelectrodes and the type of neurophysiological recordings introduced in Section 2.7. In the case of the retina, it is evident where to place the microelectrodes to examine function. However, there are about 1011 neurons in the human brain, and we do not have any tools that enable us to record from all of them. How do we figure out what parts of the brain are relevant for vision so we can study them at the neurophysiological level?
