The superior colliculus is a brain structure responsive to both visual and auditory stimuli, with its auditory receptive field shifting based on eye position.

“It takes place in a structure called the superior colliculus, although you don't need to know that name. Superior colliculus has layers, literally stacks of neurons like in a sandwich where the zero point right in front of me, or maybe 10 or 15 degrees off to my right or 10 or 15 degrees off to my left, are aligned so that the auditory neurons, the ones that care about sounds, at 15 degrees to my right, sit directly below the neurons that look at 15 degrees to my right in my visual system.”
