Peak-normalized deconvolved responses of GCaMP8s signals in responsive ROIs following stimulus presentation (at full contrast, averaged across all orientations) are shown as mean ± SEM overN= 22 sessions for PV-INs (n= 429 ROIs, 9 mice) andN= 15 sessions for SST-INs (n= 382 ROIs, 7 mice). Mean values in the [0.8,2] s interval (highlighted by a gray line): 0.68 ± 0.02 (SST-Cre,N= 15) vs. 0.40 ± 0.03 (PV-Cre,N= 22), Mann-Whitney U test:p< 0.001. The inset shows a zoom of the [−0.1, 0.3] s window. Delays to peak onset: 0.19 ± 0.01 s (PV-Cre,N= 22) vs. 0.63 ± 0.14 s (SST-Cre,N= 15), Mann-Whitney U test:p< 0.001.
