Figure 2. ESC-derived serotonin neurons elicit action currents.

Figure 2

A) Representative serotonin neuron. B) Action currents in depolarizing voltage step −70 mV to −30 mV. Voltage-dependent sodium channel implicated by absent action potential during TTX superfusion, recovers after washout. C) Currents evoked by depolarizing 10 mV voltage steps, D) presence of GABA. E) Current-voltage plot of the subtracted (GABA-control).
