We use our experimental results to develop and refine computational models of how the brain processes spatial auditory cues. Models of brainstem activity explore what information is robustly encoded in relatively peripheral portions of the brain. Such physiologically-based models allow us to investigate integration of spatial information over time and frequency. Our goal is to understand how spatial information is represented in neural populations at different stages of the auditory processing pathway and how experience influences spatial processing at different levels of the auditory pathway, from brainstem to cortex.
