Spatial Processing [click left for another topic]
The question of how spatial cues are extracted from acoustic signals and encoded in different stages of neural circuitry is much studied, in part because of the beauty of the specialized brainstem circuitry that is known to support spatial perception. We have been involved in numerous psychophysical, acoustical, and modeling studies to understand spatial auditory processing in everyday settings, including settings with multiple sources and acoustic reflections.
