Spatial hearing permits us to identify the locations of sound sources and to isolate sounds of interest from the confusion of competing sounds. I will consider some evolving views of how the locations of sounds are written in patterns of cortical activity, will show that these patterns vary on a time scale of minutes depending on an animal’s listening state, and will present some preliminary psychophysical and physiological results on spatial release from informational masking and spatial stream segregation.
