Spectral modulation selectivity of MNTB neurons are sufficient to encode the spectral modulations contained in spatial head related transfer functions. (A) The directional transfer function (DTF) for a sound source located at (0°, 0°). (B) Spectral modulation distribution of the DTF in (A), the ensemble of RSS stimuli, and the ensemble of DTFs used in this study plotted as mean ripple depth (dB) as a function of ripples/octave. DTFs have large ripple depth at low ripples/octave while RSS have constant mean ripple depth up to at least 4 ripples/octave. (C) Spectral modulation selectivity of the population of MNTB neurons in terms of spectral weighting (spikes/s/dB) as a function of ripples/octave. MNTB neurons preferentially resolve low spectral modulations consistent with those provided by the DTFs.
