Extended Data Fig. 10: Relationship between tuning and selectivity index examples and composite view.
From: Spatially clustered neurons in the bat midbrain encode vocalization categories

a, Tuning map for example site in Fig. 4 color-coded according to the best frequency of the neuron. b, Corresponding social/navigation selectivity map for the same example site, color-coded by the neuron’s selectivity index. Note that the selectivity ‘hotspots’ do not follow the tonotopic gradient. c, Cumulative distribution for cluster centers and corresponding shuffle distribution (randomly selected from all cells coordinates, in gray) along the composite RL gradient of all imaged sites. Left: social cluster falls just outside of the shuffle distribution (two-sided permutation test, p < 0.01), perhaps due to the increase in cluster size with cell density. Center left: navigation cluster centers fall within the 95% confidence interval therefore following cell density independently of the tonotopic gradient. Center right: cells tuned to low frequencies (4 and 5.7 kHz, in dark blue) are located more rostromedially than the corresponding shuffled distribution (two-sided permutation test, p < 0.01). Right: cells tuned to high frequencies (16 and 22.7 kHz) are located more caudolaterally than the corresponding shuffled distribution (two-sided permutation test, p < 0.01).
