WebJan 5, 2024 · With infusion of 16 mM K +, depolarization of the resting membrane potential was accompanied by graded reduction in the AP peak from a maximum ranging from +15 to + 35 mV down to –25 to –45 mV (Figure 2C, D and E). Between resting potentials of –65 to –52 mV, there was rapid reduction of the peak with further depolarization.
