Researchers exposed rat stomach tissue to electrical currents at frequencies from 10 to 1,000 Hz and found that both alternating and square wave currents caused the stomach lining to depolarize (lose its electrical charge). While acid production remained normal, the electrical properties of the stomach tissue changed significantly, suggesting direct effects on cellular membranes.
