INTRODUCTION: Natural hallucinogens have been known since ancient times and were widely used in religious, shamanic, and folk rituals, as well as in traditional medicine. These compounds originate from plants, animals, and fungi and exhibit considerable diversity. Different groups of substances vary in their mechanisms of action, receptor responses, effects induced, and therapeutic...
Natural hallucinogens derived from fungi and animals have been used for centuries in shamanic, ritualistic, and medicinal practices across diverse cultures. These compounds exhibit a widerange of structures and mechanisms of action, affecting various neurotransmitter systems pathways. Fungal hallucinogens, primarily indole alkaloids like psilocybin and ergot alkaloids, as well as animal-derived...
The abundance of research indicates that enriched environment acts as a beneficial factor reducing the risks of relapse in substance use disorder. There is also strong evidence showing the engagement of brain dopaminergic and glutamatergic signaling through the dopamine D2-like and metabotropic glutamate type 5 (mGlu5) receptors, respectively, that has a direct impact on drug reward and drug...
Several studies strongly support the role of the dopamine D2-like and glutamate mGlu5 receptors in psychostimulant reward and relapse. The present study employed cocaine or MDMA self-administration with yoked-triad procedure in rats to explore whether extinction training affects the drug-seeking behavior and the D2-like and mGlu5 receptor Bmax and Kd values in several regions of the animal...
