Fig. 4 — a, Patch-clamp electrophysiology analysis of pairs of Sst44 cells in brain slices. b, The mean membrane voltage (V_m) from an example connected pair. c, Expanded view of b to display the delay. The V_m for cells 1 and 2 are offset for visualization. d, The delay in the V_m of the follower cell for strong connections (Methods). Mean: 1.2 ms, 5 connections. e, Connection strength (∆V_m in the follower cell/∆V_m in the driver cell) from all pairs. A total of 14 out of 26 pairs (54%) were connected. Statistical analysis was performed using Wilcoxon signed-rank tests with Benjamini–Hochberg correction; P < 0.01. f, The connection strength for connected pairs with similar series resistance (<30% difference), showing that the connection strength is reciprocal. g, The mean V_m for the pair in b after adding inhibitors for NMDA (D-AP5), AMPA (NBQX) and GABA_A (gabazine) receptors. h, The connection strength before and after adding synaptic blockers.
