Comparative electrical properties of identified neurons in Elysia chlorotica before and after low salinity acclimation.
Identified neurons in the abdominal ganglion of Elysia chlorotica adapted to 50% seawater (SW) had significantly different electrical properties from the same cells in animals adapted to 100% SW. Resting potential, action potential (AP) overshoot, (AP) duration, threshold and after potential were all different following salinity acclimation. The resting potential of these cells behaves as an ideal potassium electrode above 10 mM [K+]. The action potential has both sodium and calcium components to the rising phase.
