Highlights•Neural representation of ITD in human cortex is sparse and sound-frequency dependent•Cortical activation to ITD is correlated with spatial perceptual qualities•Scaled for head size, humans and macaques show a common cortical representation of ITD•Our findings suggest a common representation of ITDs across mammalian cortexSummaryHumans make use of small differences in the timing of sounds at the two ears—interaural time differences (ITDs)—to locate their sources.
