Original recording (A), current–voltage (I-V) curve (B), and mean data (C) of the voltage-gated Na+currents in undifferentiated and differentiated NG108-15 cells, measured by whole-cell voltage-clamp technique. Data are means ± SEM, n = 10 cells in each group. *P < 0.05 vs. cells after 21days of differentiation with action potential (AP).
