title: Optical probing of active membrane potential using lasers and microoptics.
abstract: We developed an optical probing system of active membrane potentials using lasers and microoptics. We measured the action potential of carp heart by multiple-wavelength and multiple-site optical probing system. Taking advantage of the coherent laser beam, an optical microprobing method for micro-study on ion channel activity is proposed.
