(A) Raster plot showing IpN spikes during paired trials in 4 cells that show a blunted peak response around the CS-complex spike latency. (B) Average spike traces for the cells in A. (C) Minimum spike rate in the CS-US interval did not seem more or less pronounced in suppressive cells with this blunted peak (Pk, −33.6 ± 15.4 Hz) compared to those without (−34 ± 9.6 Hz, p=1, MWU). (D) Same as C, here showing no difference in spike rate velocity (−2.1 ± 1.4 vs −1.2 ± 0.7 Hz/ms, p=0.2096, MWU). (E) Same as C, here showing no difference in recording depth (2048 ± 181 vs 2120 ± 36 um, p=0.7348, MWU).
