The bar of light moves across the screen.

A moving bar of light stimulates receptive fields in the retina.

As the cat views the screen, the electrode records activity in single cells in the occipital cortex.

Ganglion Receptive Field

On-center ganglion cell receptive field

Retinal ganglion cells that are aligned project to thalamic relay cells that relay information to cortex.
