Webb24 mars 2024 · Much of the initial support for this theory came from non-human animal research showing that opioid receptor agonists such as morphine are highly effective at alleviating separation distress across a variety of species (Panksepp et al., 1978; Kalin et al., 1988)—a finding consistent with the theory that separation distress reflects a state of …
Receptor theory is the application of receptor models to explain drug behavior. Pharmacological receptor models preceded accurate knowledge of receptors by many years. John Newport Langley and Paul Ehrlich introduced the concept of a receptor that would mediate drug action at the beginning of the 20th century. Alfred Joseph Clark was the first to quantify drug-induced biological responses (specifically, f-mediated receptor activation). So far, nearly all of the quantitative theo…
