Effects of alpha-toxins from Bungarus multicinctus and Bungarus caeruleus on cholinergic responses in Aplysia neurons.

The effects of alpha-bungarotoxin from Bungarus multicinctus and Bungarus caeruleus were studied on three types of cholinergic response in Aplysia central neurones. These responses are the result of three distinct changes in ionic permeability: selective increases in permeabiliyt to Na, Cl and K, respectively. It was shown that 10(-5) M alpha-bungarotoxin… (More)
