Recording of Intracellular Electrical Activity with Microelectrodes

摘要: Six decades ago, Fuchs (1910) and Brucke independently recorded electrical current from the smooth muscles of uterus, ureter, retractor penis (see review Evans, 1926). Action potentials muscle were first in vivo by Alvarez Mahoney (1922), vitro, stomach muscle, two years later (Richter, 1924). Preliminary analysis active membrane potential various muscles, e.g., urinary bladder, nictitating membrane, pilar was made Rosenblueth (1950). He classified action into an initial (or spike) a delayed potential.
