nAnelectrotonus(Physiol) The condition of decreased irritability of a nerve in the region of the positive electrode or anode on the passage of a current of electricity through it.
Century Dictionary and Cyclopedia
nanelectrotonusThe peculiar condition of a nerve (or muscle) in the neighborhood of the anode of a constant electric current passing through a portion of it. The irritability is diminished, the electrical potentials are increased, and the conductivity for nervous impulses is diminished. The wave of lowered potential which attends a nervous impulse and gives rise to currents of action diminishes in going from a region of greater to one of less anelectrotonus, and increases in going in the opposite direction. The nervous impulse itself presumably behaves in the same way.
Chambers's Twentieth Century Dictionary
nAnelectrotonusan′el-ek-trot′on-us (phys.) the diminished excitability of a nerve near the anode of an electric current passing through it
nAnelectrotonusa body which readily gives up its electricity
Webster's Revised Unabridged Dictionary
NL., fr. Gr. up + E. electrotonus,
The increased excitability at the kathode is katelectrotonus, and the lowered excitability at the anode anelectrotonus.
