Pitch perception has been a focus of auditory research for over a hundred years. Yet despite this, we still do not have a clear explanation for how pitch is represented by neurons in the auditory system. Two rival theories have slugged it out over the years: 'place theory', in which pitch is determined by which neurons are active, and 'temporal theory', in which pitch is determined by how the neurons are active, specifically in terms of their temporal firing patterns. Although temporal theory has had the ascendency for a number of years, recent findings suggest that place theory may be ready for comeback.
