Heuvel, in Comprehensive Toxicology, 2010 2.03.2.1 Receptors and Chemical Selectivity. Although Claude Bernard did not talk about receptors per se, he demonstrated that the effects of a drug or toxin (in his case curare) depended on its ability to access a particular site of action, what he called a locus of drug effect. Bernard concluded from a …
