The effect of blockers on membrane potential hyperpolarization caused by glucose deprivation in SNr neurons.

<p>(A) A continuous recording of membrane potential. (B) 1–4 represent expansions of the corresponding times in (A). (C) Histogram of the membrane potential at the start of the glucose deprivation treatment (<i>V_m0</i>; <i>t</i> = 0), minimum membrane potential (<i>V_mmin</i>), which corresponds to maximum hyperpolarization, and the onset of the initial TEA effect (<i>V_m</i>|<i>_TEA</i>). (D) Time from the start of the glucose deprivation treatment (<i>t</i> = 0) to the onset of the minimum membrane potential corresponding to maximum hyperpolarization, or the initial TEA effect, at the time <i>t</i>|<i>_Vmmin</i> or maximum gray value at the time t|_TEA. ^*, <i>P</i><0.05; ^*****, <i>P</i><0.0001.
