What Are Psychedelic Drugs Hallucinogenics?

Their findings were consistent with the observation of a dense band of 5-HT2 receptors in upper cortical layer V in register with a dense plexus of fine 5-HT axons (Blue et al., 1988). A mRNA in situ hybridization study of human cortex demonstrated the 5-HT2A receptor on both pyramidal and nonpyramidal cells (Burnet et al., 1995). In a subsequent study, it was found that Sr2+ fully substituted for Ca+2 in supporting the 5-HT–induced increase in spontaneous EPSC frequency, but only partially with respect to amplitude . In the presence of Sr2+, however, late asynchronous evoked EPSPs followed each electrical stimulus, with an absence of synchronous EPSCs.

Psychedelic microdosing is the practice of using sub-threshold doses of psychedelics in an attempt to improve creativity, boost physical energy level, emotional balance, increase performance on problems-solving tasks and to treat anxiety, depression and addiction. The practice of microdosing has become more widespread in the 21st century with more people claiming long-term benefits from the practice. Soon musicians began to refer to the drug and attempted to recreate or reflect the experience of taking LSD in their music, just as it was reflected in psychedelic art, literature and film. This trend ran in parallel in both America and Britain and as part of the interconnected folk and rock scenes. As pop music began incorporating psychedelic sounds, the genre emerged as a mainstream and commercial force. From 1967 to 1968, it was the prevailing sound of rock music, either in the whimsical British variant, or the harder American West Coast acid rock.

Whereas several psychedelic drugs, including LSD, demonstrated potent anti-inflammatory effects, the drug R-DOI was extraordinarily potent at blocking inflammation. IC50 concentrations for R-DOI inhibition were very low (in the range of only 10–20 pM), and significant inhibition could be observed even if R-DOI was added several hours after TNF-α treatment. They coadministered DOI along with GABAA and GABAB receptor agonists and antagonists, and investigated effects on the four-plates test of anxiety in mice. Low doses of DOI that had no effect alone in the four-plates test were significantly potentiated by alprazolam and diazepam, but not by flumazenil. Their results, as well as a number of articles cited showing the expression of 5-HT2A receptors on GABA neurons, led these authors to hypothesize that 5-HT2A receptor activation on GABA neurons increases GABA release, which stimulates postsynaptic GABAA receptors. In a separate study, Masse et al. microinjected DOI into the mouse hippocampus, amygdala, or periaqueductal gray matter and then immediately subjected the mice to the four-plates test to assess anxiety.

For example, LSD has effects at a variety of GPCRs other than the 5-HT2A receptor, the presumed principal target for Psychedelics. Although DOI appears to be primarily an agonist at 5-HT2A and 5-HT2C receptors, it lacks effects at most other receptors. By contrast, psilocybin and many other tryptamines are also agonists at the 5-HT1A receptor.

RNase protection was used to validate these genes as differentially expressed, in the PFC, along with Arc and c-fos. Krox-20 (egr-2) has been shown to be necessary for normal brain development and may be involved in the maintenance of long-term potentiation (see references in Nichols and Sanders-Bush, 2002). González-Maeso et al. then compared effects on in vivo gene expression of three agonists evaluated in the HTR. Transcript levels in the mouse somatosensory cortex 1 hour after agonist injection were compared by quantitative reverse-transcription polymerase chain reaction to those from vehicle-injected controls. Thirteen transcripts showed significant changes after at least one agonist, with each agonist showing a unique and reproducible transcriptome fingerprints. Of the genes identified, only early growth response protein 1 (egr-1), early growth response protein 2 (egr-2), and period-1 were similarly activated by DOI and LSD but were unaffected by lisuride.
