"Individuals determine horizontal sound location based on precise calculations of sound level and sound timing differences at the two ears. Although these cues are processed independently at lower levels of the auditory system, their cortical processing remains poorly understood. This study seeks to address two key questions. (i) Are these cues integrated to form a cue-independent representation of space? (ii) How does active listening to sound location alter cortical response to these cues? We use functional brain imaging to address these questions, demonstrating that cue responses overlap in the cortex, that voxel patterns from one cue can predict the other cue and vice versa, and that active spatial listening enhances cortical responses independently of specific feat​ures of the sound."
