A Meter for Sound Location in the Auditory System

In the auditory system, figuring out where sounds are located is intrinsically a computation that the brain has to be performing by compare the two ears. So as i started trying to build models of how you might convert auditory signals into an eye based frame of reference for communication with the visual system, i realized that how that computation might unfold would be different depending on whether or not there's map for sound location. We have come to call a meter for sound location - instead of identity of which neurons are active, signifying where the sound is coming from. You could also imagine doing it with the amount of activity in a population of norons, signalling whether or not the sound is more over to this side
