Across the population, NSR neuron centroids were more broadly distributed in 2D space compared with FMSR neurons. A, B, Distribution of centroid azimuths in FMSRs and NSRs recorded at 10 dB (A) and 20 dB (B) above threshold. C, D, The distribution of centroid elevation in FMSRs and NSRs recorded at 10 dB (C) and 20 dB (D) above threshold. The dashed lines in A and B demarcate ipsilateral (IPSI) and contralateral (CONTRA) azimuth locations. The dashed lines in C and D demarcate the upper and lower elevations.
