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

因此，血中低钾时，膜电位化或者说变得。

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使内，使其电荷下降——远离阈值，从而使突触后神经元化。
