Extended Data Fig. 4: Acoustic distribution of vocalization.
From: Spatially clustered neurons in the bat midbrain encode vocalization categories
a, Average power spectrum for each vocalization sequences normalized by its max. b, Average vocalization sequence f0 end frequency as a function of start frequency. Individual point represents each sequence (social: red, navigation: blue, mouse USVs: orange). Black circles highlight the stimuli presented in Fig. 3, all stimuli were presented for Extended Data Fig. 7a, b. Conspecific sequences end and start frequency are significantly different (mean social: 22.9 and mean navigation: 29.7 kHz KW test, p = 0.012 and p = 9.2e-4, respectively). c, Average vocalization duration as a function of duration. Social and navigation sequences can be separated by duration (mean social: 8 ms, mean navigation: 4.5 ms, KW test, p = 4.9e-4). d, Vocalization f0 slope as a function of f0 peak frequency. Social vocalizations present shallower slopes (mean social: 0.08 oct./ms, mean navigation: 0.17oct./ms, KW test, p = 3.5e-4).
