In experienced females, prototype- and morph-evoked EPSCs are similar and negatively correlated with ISI; in naive cortex morph-evoked EPSCs are weaker than prototype-evoked ones and uncorrelated with ISI.

What the paper reports
- NV 175 against 125 ms: repeated measures one-way ANOVA, Bonferroni correction, p = 0.006
- NV 175 against 275 ms: repeated measures one-way ANOVA, Bonferroni correction, p = 0.003
- NV 175 against 575 ms: repeated measures one-way ANOVA, Bonferroni correction, p = 0.02
- EV EPSC against ISI: two-tailed Pearson correlation, r = -0.37, p = 0.01 (n = 12 cells)
- NV EPSC against ISI: two-tailed Pearson correlation, r = -0.13, p = 0.35 (n = 14 cells)
In the deposited in vivo recordings the current almost never follows the calls, so the claim cannot be tested on the cells it is about. The Methods' evoked measure is in the expected direction at p < 0.05 in 2 of 39 cell recordings, against 3 of 39 for the same measure before the call; no cell has a mean response 0-300 ms after onset at p < 0.05 (mean over cells 0.25 pA for EPSCs); 13 of 110 files have a sweep-locked deflection 0-3 s after onset at p < 0.05, more than the 5.5 expected by chance (binomial p = 0.0034), but only 3 of them, from two cells (naive 190326_e1, both EPSC files, and experienced 190313_e2, one of two), carry a current in the expected direction during the call, first exceeding the null 0.39 to 0.51 s after onset and peaking at 37 to 48 pA; the other 10 peak at scattered times, 9 against the expected direction; and the inclusion rule keeps 1 of 39 (2 s.d., cell 190326_e1) or none (3 s.d.). As computed on every listed cell it would not be reproduced: naive prototype-evoked EPSCs (20.0 pA, largest 5 trials) are not larger than morph-evoked ones (17.4, 18.3, 16.2 pA; adjusted p 0.12, 0.94, 0.20; RM ANOVA p = 0.18), and no variant gives p < 0.05 for all three; experienced EPSCs are not correlated with ISI (r = -0.14, p = 0.35; -0.09 to -0.21 under every variant). No experienced pair differs (smallest adjusted p 0.30 to 1.0) and the naive correlation is not significant (r = -0.07, p = 0.61).
How the test differed from the paper’s method
- Call onset, offset and ISI come from the recorded microphone channel. The onset is the start of the sound (envelope above its median by 6 robust s.d.); before revision it was the first loud syllable, which came a median 193 ms (up to 644 ms) late because the first syllable of many calls is quiet, and that rule is run as a variant. In 82 of 83 morph-set files the four call durations form four groups in a fixed order (prototype, 125, 275, 575 ms), and the ISI is assigned by duration rank; one two-sweep file uses the nearest bin of the measured gap. The sets hold the legends' ISIs, not the Methods' 125, 225 and 575 ms.
- Assumed, for the Methods' inclusion rule ("Only neurons that exhibited at least five significant prototype-evoked E/IPSCs"), which does not define a significant PSC: a trial whose evoked current in the expected direction exceeds k s.d. of the cell's sham measure (k = 2 and 3). It keeps 1 of 39 cell recordings at k = 2 and none at k = 3; the other checks of the data check, which need no such definition, agree that the currents almost never follow the calls (two cells carry an inward current during the call).
- Every listed cell is used for the computed values; 12 experienced and 14 naive EPSC cells as in the paper, and 7 experienced (paper 6) and 6 naive IPSC cells. One experienced IPSC cell (190410_e1) has 4 or 5 trials per ISI.
- The largest 5 or 10 trials are ranked by absolute value (the Methods' "absolute magnitudes"), and, as a second reading, by the current in the expected direction.
- The spreadsheet notes are applied (stop or drop at a sweep keeps the sweeps before it, from sweep N keeps the later ones, drop or block + stop drops the file), only the best call's set is used where a note names one, and sweeps whose holding current contradicts the listed potential are dropped (file 19424013 is listed at -70 mV but carries +560 pA). Using every sweep is a variant.
- Experienced cells pool dams and EVs; the spreadsheets do not say which are which.
- One listed file (193260007, an IPSC file of naive cell 190326_e1) is not on figshare; the cell's other IPSC file is used.
- The Bonferroni family is read as the three comparisons with the prototype that the legend reports; all six pairs are shown.
