Some types of nerve fiber show certain of these electrical waves more clearly than others; a composite picture of the electrical disturb- ance in a nerve impulse follows: (1) The membrane has electrical capacitance and resistance, and when subthreshold current is passed through the nerve there is current spread ac- cording to the electrical constants of the membrane. This electrotonic wave declines exponentially along the fiber from the source of stimulation and. Fig. 291. Local graded oscillations with emergent spike in decalcified giant axons of squid. From ;.
