Relationship between CF and centroid azimuth or centroid elevation of NSR and FMSR neurons recorded at two different sound levels, MT + 10 dB (left column) and MT + 20 dB (right column). A, B, In NSR neurons, the CF and centroid elevation were significantly correlated at both sound levels. C, D, In NSR neurons, no significant relationship was observed between CF and centroid azimuth. E–H, In FMSR neurons, no significant relationship was seen between CF and centroid azimuth or elevation.
