FIG. 5.

Effects of calcium channel inhibitors on depolarization-induced action potentials in neuron-like cells differentiated from neural stem cell–like cells. (A) The depolarization-induced action potentials were not affected by 1 mM nickel chloride (NiCl₂). However, the amplitude of the steady-state depolarization changed. (B) The action potential shape and the steady-state depolarization were altered by 10 μM cadmium chloride (CdCl₂). Resting membrane potential (mV) is indicated to the left of the voltage recordings. Recordings are representative examples.
