Changes in activity parameters of AC neurons after AAT. A: changes in spontaneous firing rate (SFR) of PV−, PV+, SST−, and SST+ neurons in L4. B: changes in pure-tone-evoked firing rate (PT-EFR) of PV−, PV+, SST−, and SST+ neurons in L4. C: changes in broadband noise evoked-to-spontaneous firing rate (BBN-ESR) of PV−, PV+, SST−, and SST+ neurons in L2/3. D: changes in pure-tone evoked-to-spontaneous ratio (PT-ESR) of PV−, PV+, SST−, and SST+ neurons in L2/3. Two-tailed two-sample permutation test, Bonferroni correction for multiple comparisons; n = 2 for A and B and n = 6 for C and D. *P < 0.05, **P < 0.01.
