Fig 6. PV interneuron response latency depends on stimulation layer.

A. Raw latencies (not divided by distance) and B. Normalized latencies (to distance) for PV interneuron responses to stimulation in L2/3 (orange) or L4 (green). Regardless of residence layer, responses elicited by L2/3 stimulation (orange) have longer distance-normalized latencies than those elicited by L4 stimulation (green, F(1,51) = 16.478, p < 0.001). Both boxplots are nonparametric.
