1. The action of four different toxins from the venom of the scorpion Androctonus australis which have been previously purified and specified according to their fly larvae and isopod paralysis (insect and crustacean toxin) and mice lethality (mammal toxin I and II) have been tested on a nerve muscle preparation and on the giant axons of the crayfish Astacus leptodactylus.

The effects of 1–100 nM Lqh III, an α-like toxin isolated from the scorpion Leiurus quinquestriatus hebraeus, were assessed on the nodal membrane potential and ionic currents of single frog myelinated axons.In current-clamped axons, Lqh III increased the duration of action potentials without markedly affecting the peak amplitude and the resting membrane potential.

This lecture describes the details of the neuronal action potential. The lecture starts by describing the electrical properties of non-excitable cells as well as excitable cells such as neurons. Then sodium and potassium permeability properties of the neuronal plasma membrane as well as their changes in response to alterations in the membrane potential are used to convey the details of the ...
