Some neurons and other excitable cells (eg pacemaker cells in the heart, interstitial cells of Cajal in the smooth muscle of the gut) generate action potentials spontaneously in a rhythmical pattern.

The neurotoxins act on sodium channels of excitable cells, either by retarding inactivation (an [alpha]-toxin) or enhancing activation (a [beta]-toxin) leading to spontaneous depolarisation of excitable cells.
This maintains excitable cells in a depolarized state, in which they behave like cholinergic agents and cause dose-dependent hypotension, bradycardia and respiratory-rate depression (3).
