Mouse astrocytes (glial cells) in primary cultures were exposed to a low‐voltage static DC electric field with no current flow and thus with no generation of magnetic fields. The electric field altered the rate of glycolysis, measured by 2‐deoxyglucose accumulation. The magnitude and direction of this effect depended on the polarization of the field and the applied voltage. The maximum effect was an increase of ∼30%, which occurred with field across the cells at an intensity that can be calculated to be 0.3 mV/cm or less. Reversal of the polarization converted the stimulation to a small but statistically significant inhibition. Bioelectromagnetics 18:77–80, 1997. © 1997 Wiley‐Liss, Inc.
