Abstract
Summary
1. Stimulation of nerve by electrical fields associated with the charging and discharging of condensers has been obtained, although the efficacy of increasing and decreasing fields is not identical; 2. a strength-duration curve of excitation with diminishing electrical fields associated with the discharge of condensers has been determined wherein E is at first a decreasing and then an increasing negatively accelerated function of the time. The region of inversion is between .0001 and .00038 mscs; 3. the curve is in marked contrast with those obtained by discharging condensers through nerve tissue, in that these (a) are not characterized by an inversion, (b) show E as a diminishing negatively accelerated function of the time; 2 4. there are great differences in the stimulability of preparations.
