Micropuncture of bovine lens epithelial cells cultured on plastic culture dishes gave values
for the plasma membrane voltage (V) which remained stable for periods of up to several
hours. The value of V was mainly in the range− 30 to− 45 mV, mean value− 36· 9±0· 5 mV
(sem, n= 188). Raising extracellular [K+] from 5 to 40 mm depolarized V by 10±3 mV. The
extent of this depolarization increased with increasing steady-state V. Barium (2 mm) caused
a rapid, reversible depolarization of 7· 9±1· 2 mV. In the presence of Ba 2+, the response to …
