So, with low potassium in the blood, the membrane potential can hyperpolarize, or become more negative.

因此，血中低钾时，会超极化或者说变得更负。

But an inhibitory neurotransmitter hyperpolarizes the postsynaptic neuron by making the inside more negative, driving its charge down — away from its threshold.

但是抑制性神经递质通过内部更负，荷下降——远离阈值，从而突触后神经元超极化。
