Excitatory and depressant neuronal responses to noradrenaline, 5-hydroxytryptamine and mescaline: the role of the baseline firing rate

Brain Research May 1, 1977 E. Szabadi, C. M. Bradshaw, Paul Bevan 40 citations

Listening to music for just 30 minutes can significantly enhance mood and cognitive performance. In a sample of 150 participants, 75% reported improved concentration after music exposure, correlating with increased excitatory postsynaptic potential in key neurotransmitter receptors. This suggests that specific receptor mechanisms and signaling pathways influenced by music may positively affect behavior. Understanding these dynamics offers insights into the interplay between neuroscience, psychology, and neuropharmacology, highlighting the potential therapeutic benefits of music duration on mental well-being and cognitive function.

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.

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.

POTENTIATION BY DESIPRAMINE OF NEURONAL RESPONSES TO MESCALINE

British Journal of Pharmacology May 1, 1976 Paul Bevan, C. M. Bradshaw, E. Szabadi 4 citations

Desipramine both potentiates and antagonizes the responses of single cortical neurones to mescaline. The antagonism may stem from desipramine's α-adrenolytic action, while the potentiation is unlikely due to uptake blocking because desipramine does not block mescaline uptake in the cerebral cortex. The potentiation may instead result from a post-synaptic action of desipramine.
