Lowering the solution conductivity from 16.4 to 8.4 mS/cm reduces excitation thresholds approximately 2-fold across the range of sine wave frequencies from 2 to 20 kHz. The thresholds were defined as the minimum electric field strength to elicit at least one action potential during a 250-ms-long stimulation with unmodulated sine waves. Mean ± SEM; 4–8 neurons tested per each datapoint. Dashed lines are best fits using the exponential function.
