NRG1 does not affect potassium currents. A, B, Representative traces of K_v channel currents from ErbB4+ interneurons with NRG1 (A) or vehicle application (B) for baseline, 10 min, and 20 min recordings. C, D, Averaged I/V relationship for K⁺ current density showing a lack of effects with NRG1 (n = 8; C) or vehicle (n = 6; D). E, Individual K⁺ channel current responses to NRG1 (left) or vehicle application (right) at 20 min are plotted with their own baseline (gray lines). Average response depicted with a black line.
