The refractory period in a neuron occurs after an action potential and generally lasts one millisecond. An action potential consists of three phases. Phase one is depolarization. During depolarization, voltage-gated sodium ion channels open, increasing the neuron's membrane conductance for sodium ions and depolarizing the cell's membrane potential (from typically -70 mV toward a positive potential). In other words, the mem… WebMar 15, 2024 · Objective: To analyze the effect of escitalopram oxalate (ESC) plus low-dose (LD) trazodone (TRA) on the psychological state and quality of life (QOL) of patients with treatment-refractory depression (TRD).
