Regional distribution of the Na+ and K+ currents around the crystalline lens of rabbit

Early studies described asymmetrical electrical properties across the ocular lens in the anterior-to-posterior direction. More recent results obtained witha vibrating probe indicated that currents around the lens surface are not uniform by showing an outwardly directed K+ efflux at the lens equator...

More Information
Summary:Early studies described asymmetrical electrical properties across the ocular lens in the anterior-to-posterior direction. More recent results obtained witha vibrating probe indicated that currents around the lens surface are not uniform by showing an outwardly directed K+ efflux at the lens equator and Na+ influx at the poles.
