a, Distribution of fundamental frequencies in budgerigar vocalizations shows a clear minimum at 700 Hz. b-d, Distribution of the selectivity index for low frequency (b), harmonic (c), and noisy (d) vocalizations across the AAC population. Colored bins indicate neurons with a selectivity larger than 0.5 for each index. e, Venn diagram displaying the number of neurons with selectivity indices larger than 0.5 for each of the three categories.
