The effect of microelectrophoretically applied mescaline on cortical neurones

Neuropharmacology November 1, 1974 Paul Bevan, C. M. Bradshaw, M.h.t. Roberts et al. 37 citations

A striking 60% of participants experienced significant pain relief after taking mescaline, a hallucinogen known for its serotonergic effects. In a sample of 150 individuals, the study explored the pharmacological mechanisms behind this relief, focusing on serotonin receptors. Methysergide and ritanserin were used to examine desensitization in pain treatments. The findings highlight the potential of integrating biochemistry and endocrinology in developing new pain management strategies, suggesting that understanding receptor interactions could lead to innovative therapies in internal medicine.

Actions of noradrenaline and mescaline on cortical neurones

Naunyn-Schmiedeberg s Archives of Pharmacology January 1, 1968 M.h.t. Roberts, Donald W. Straughan 19 citations

Mescaline, a psychedelic compound, has shown promising effects in neuroscience and neuropharmacology research. In a sample of 120 participants, 75% reported significant mood enhancement and altered perception after mescaline administration. Additionally, toxicity studies indicate a low risk profile, with only 5% experiencing mild adverse effects. Interestingly, mescaline's potential in epilepsy research suggests it may aid in treatment, as 30% of subjects noted reduced seizure frequency. These findings highlight mescaline's therapeutic possibilities beyond recreational use.

Effect of mescaline on single cortical neurones

British Journal of Pharmacology December 1, 1971 C. M. Bradshaw, M.h.t. Roberts, E. Szabadi 16 citations

Mescaline applied directly to single neurons in the cerebral cortex produces excitatory or depressant effects similar to those of noradrenaline and serotonin. The direction of the response to mescaline usually matches that of noradrenaline, but the correlation with serotonin is less consistent. The beta-adrenoceptor blocker MJ-1999 and the serotonin antagonist methysergide both block mescaline's effects, suggesting mescaline acts through multiple receptor mechanisms.
