LSD-25 has dramatic and reversible effects on behaviour in monkeys. I t was thought necessary to study development to tolerance to the drug in this species before proceeding to a study of its effects on memory and learning. The effects of large doses of d-lysergic acid diethlyamide (LSD-25) injected intravenously into monkeys ( M a c a c a mulat ta) have been described (EvAnTS 1956). Several observations have been made on development of tolerance to LSD-25 in different species (AB~AMSON et al…

The behavioural effects of levallorphan, cyprenorphine (M 285) and amphetamine on repeated Y-maze performance in rats

The effects of levallorphan and cyprenorphine (M 285) were studied on repeated Y-maze performance in rats and Amphetamine increased locomotor activity without affecting habituation.

Impairment by lysergic acid diethylamide of accuracy in performance of a delayed alternation test in monkeys

It is suggested that the partial similarity of the effects of LSD to those obtained in monkeys following bifrontal lesions may reflect the operation of some common factor.

The striking mental changes induced by the diethylamide of lysergic acid (hereafter referred to as LSD) have been studied extensively in Europe, Great Britain and the United States and are apparently the most effective and safest agent for inducing an experimental, but reversible, psychosis in nonpsychotic subjects.

Bufotenine was recently isolated from the bean of Piptadenia peregrina, a bean long known to be the source of cohoba, a narcotic snuff, which has been used by inhabitants of the West Indies to induce hallucinations and mystical states.
