  • Neurons in the control group express DsRed protein alone; the mutant group contains TG neurons coexpressing DsRed protein and MT TRESK subunits. Rin was calculated by measuring the change of membrane potential in response to a 20 pA hyperpolarizing current injection from Vrest.

  • *p < 0.05 compared with the corresponding control group by two-tailed t test.
