Paralleling this upswing, the pharmacologists have made available a group of synthetic materials that have the capacity to intrude on the action of this part of the nervous system. One member of this group which has received especial attention is tetraethylammonium. It has the ability to block the transmission of impulses through autonomic ganglions, both sympathetic and parasympathetic.
