Computing the location(s) of sound(s) in the visual scene

I will discuss two topics concerning visual and auditory spatial coding: 1. Early cross-talk between vision and hearing, in which eye movement signals trigger eardrum oscillations and create faint saccade-related sounds. 2. A new theory of neural coding, involving multiplexing of signals via fluctuating activity patterns. Such multiplexing could allow representations to encode more than one simultaneous visual or auditory stimulus. These findings emerged from experimentally testing computational models, highlighting the importance of theory in guiding experimental science.
