title: Electrical activity of mouse motor nerve terminals.
abstract: Focal extracellular recording was made from presynaptic motor nerve terminals made visible directly in in vitro preparations of mouse intercostalis intimi muscles. The demonstration of a net inward current distally in these terminals at sites of transmitter release allow the conclusion that the mammalian terminal is electrically excitable, contrary to a recent claim that it is not.
