Mind the Psychedelic Hype: Characterizing the Risks and Benefits of Psychedelics for Depression

Psychoactives April 16, 2024 Daniel Meling, Rebecca Ehrenkranz, Sandeep M. Nayak et al. 26 citations

Rationale: Psychedelic research re-emerged from a period of suppression into the so-called psychedelic renaissance. In parallel, most media reporting has shifted from the overstatement of the risks of psychedelics to overly positive hype. As the empirical evidence is more equivocal than frequently portrayed, the conclusions about the effectiveness of psychedelics should be considered...

Circuits for anesthesia, unawareness, OIRD, sleep and memory replay: MHb→IPN→PAG + DRN + MRN→claustrum→cortex.

April 1, 2024 Karin Vadovičová

Opiates are fast pain relievers that can cause respiratory arrest.I show new mechanisms how mu-opioids and high prenatal nicotine cause respiratory slowdownlinked to slow wave sleep. Mu-opioids activate the medial habenula which activates theinterpeduncular nucleus. The MHb-IPN system decreases respiration and alarm/arousal response tohypercapnia by projections to PAG, DRN, MRN and...

Targeting metaplasticity mechanisms to promote sustained antidepressant actions.

Molecular Psychiatry April 1, 2024 Kyle A Brown, Todd D Gould 45 citations

The discovery that subanesthetic doses of (R, S)-ketamine (ketamine) and (S)-ketamine (esketamine) rapidly induce antidepressant effects and promote sustained actions following drug clearance in depressed patients who are treatment-resistant to other therapies has resulted in a paradigm shift in the conceptualization of how rapidly and effectively depression can be treated. Consequently, the...

Altered states of consciousness

March 13, 2024 Susan Blackmore, Emily T. Troscianko 46 citations

Altered states of consciousness (ASCs) are surprisingly hard to define and to measure. Neither ‘subjective’ methods (like verbal reports) nor ‘objective’ measures (such as how the state is induced, or physiological and behavioural criteria) are entirely satisfactory. Attempts to map ASCs are reviewed, including two- or three-dimensional maps such as Tart&s;s and Laureys’, and Hobson&s;s AIM...
