Effect of relative humidity on the movement of rat vibrissae in a 60-Hz electric field

Abstract
The snouts of rats were placed in a 60‐Hz electric field at an unperturbed field strength of 50 kV/m. A count of the number of vibrissae that moved in the field was made on a series of rats over a number of days where the laboratory humidity varied from 25% to 48%. The number observed to vibrate fell from nine to zero or one at relative humidities between 25% and 39%, respectively.
