Figure 3. Most NTS neurons depolarize in response to a low glucose challenge.

A, subset of neurons depolarized by low glucose, as shown by representative recording of a responsive neuron showing a reversible depolarization and increased firing activity induced by low glucose (Aa) and summary of the low glucose effect on the membrane potential (V _m) of neurons (Ab). B, subset of neurons unresponsive to low glucose, as shown by a representative recording (Ba) and summary of the low glucose effect on the V _m of neurons (Bb). ^**** P < 0.0001.
