Emerging research suggests that the use of serotonergic psychedelics may increase feelings of connection with the natural world. However, little is known about why this might be the case. Psychedelics often elicit self-transcendent positive emotions (STPE), and recent work has provided preliminary evidence suggesting that several of these emotions may have a causal influence on people's...

3,4–Methylenedioxymethamphetamine (MDMA, “Ecstasy”) is a serotonin- and noradrenaline-releasing substance, currently among the most widely used illicit substances worldwide.

However, translation of the axonal findings, specifically, to humans has been repeatedly questioned...

The group of drugs that we are referring to includes N-methyl-d-aspartate (NMDA)...

Here we consider psychedelics with respect to their mechanisms of action, use, and implications for our understandings of brain and mind. This review is somewhat nontraditional in its scope, with discussions of both basic facts as well as theoretical speculations. We chose this approach given the unique historical context we find ourselves in at present. While we have decades of investigations...

Abstract Psychedelic serotonergic agonists such as psilocybin have recently been shown to produce sustained benefit in refractory depression, end of life anxiety, and addiction when administered in hallucinogenic doses and coupled with psychotherapy. Although it has been suggested that similar high-dose protocols may help chronic pain conditions, there are few published clinical trials of...

Serotonergic psychedelics are being studied as novel treatments for mental health disorders and as facilitators of improved well-being, mental function, and creativity. Recent studies have found mixed results concerning the effects of low doses of psychedelics ("microdosing") on these domains. However, microdosing is generally investigated using instruments designed to assess larger doses of...
