N,N‐dimethyltryptamine and Amazonian ayahuasca plant medicine

Human Psychopharmacology: Clinical and Experimental February 17, 2022 Edward James, Joachim Keppler, Ben Sessa et al. 41 citations

Abstract Objective Reports have indicated possible uses of ayahuasca for the treatment of conditions including depression, addictions, post‐traumatic stress disorder, anxiety and specific psychoneuroendocrine immune system pathologies. The article assesses potential ayahuasca and N,N‐dimethyltryptamine (DMT) integration with contemporary healthcare. The review also seeks to provide a summary of...

The Slowest Shared Resonance: A Review of Electromagnetic Field Oscillations Between Central and Peripheral Nervous Systems

Frontiers in Human Neuroscience February 16, 2022 Asa Young, Tam Hunt, Marissa Ericson 34 citations

Electromagnetic field oscillations produced by the brain are increasingly being viewed as causal drivers of consciousness. Recent research has highlighted the importance of the body’s various endogenous rhythms in organizing these brain-generated fields through various types of entrainment. We expand this approach by examining evidence of extracerebral shared oscillations between the brain and...

Methodological aspects of studying the mechanisms of consciousness.

Behavioural Brain Research February 15, 2022 Vassiliy Tsytsarev

There are at least two approaches to the definition of consciousness. In the first case, certain aspects of consciousness, called qualia, are considered inaccessible for research from a third person and can only be described through subjective experience. This approach is inextricably linked with the so-called "hard problem of consciousness", that is, the question of why consciousness has...

Neurovascular Uncoupling: Multimodal Imaging Delineates the Acute Effects of MDMA

bioRxiv Preprint Server February 14, 2022 Tudor M. Ionescu, Mario Amend, Tadashi Watabe et al. 1 citation preprint

Psychedelic compounds have attracted increasing interest in recent years due to their therapeutic potential for psychiatric disorders. Methylenedioxymethamphetamine (MDMA) is currently being investigated in clinical trials to treat post-traumatic stress disorder. To understand the acute effects of psychedelic drugs in vivo, functional MR imaging (fMRI) has been widely used in recent years....

The clinical pharmacology and potential therapeutic applications of 5‐methoxy‐N,N‐dimethyltryptamine (5‐MeO‐DMT)

Journal of Neurochemistry February 12, 2022 Johannes T. Reckweg, Malin V. Uthaug, Attila Szabo et al. 108 citations

Abstract 5‐methoxy‐N,N‐dimethyltryptamine (5‐MeO‐DMT) is a naturally occurring tryptamine that primarily acts as an agonist at the 5‐HT1A and 5‐HT2A receptors, whereby affinity for the 5‐HT1A subtype is highest. Subjective effects following 5‐MeO‐DMT administration include distortions in auditory and time perception, amplification of emotional states, and feelings of ego dissolution that...

Cannabis, alcohol, and psychosis links scrutinized by AJP

The Brown University Child & Adolescent Psychopharmacology Update February 10, 2022 Alison Knopf

The January issue of the American Journal of Psychiatry (AJP) focuses on the interactions between alcohol use, cannabis use, substance use disorders (SUDs), and other psychiatric illnesses. One of the biggest questions for clinicians treating patients with first‐episode psychosis when cannabis has been involved is the chicken‐and‐egg question — was the psychosis brought on by cannabis use or...

Game Plan and Definitions

In Consciousness we Trust February 10, 2022 Hakwan Lau

Abstract: This book will focus on subjective experience, also known as phenomenal consciousness. But this may also relate to other notions of consciousness such as wakefulness and volitional control (contra automaticity). An important distinction has been made between subjective experience and informational access. However, just because two concepts are distinct does not mean that they are...

Cannabis and schizophrenia: characterisation of a risk factor in a sample of Moroccan patients hospitalised for psychosis

Middle East Current Psychiatry February 10, 2022 El Hassan Ouanouche, Hicham Elmostafi, Naoufal Amarat et al.

In addition to the biological plausibility widely described through a very large number of studies, the causal link between cannabis uses and schizophrenia disorders has become illicit internationally and given the scarcity of similar studies in Morocco. Our study consists of a prospective descriptive study in the psychiatric department of the Moulay ben Abdallah Hospital in Essaouira. The...

Cannabis Use and Resting State Functional Connectivity in the Aging Brain

Frontiers in Aging Neuroscience February 10, 2022 K. Watson, Angela D Bryan, R. Thayer et al.

Several lines of evidence suggest that older adults (aged 65+) sharply increased their cannabis use over the last decade, highlighting a need to understand the effects of cannabis in this age group. Pre-clinical models suggest that cannabinoids affect the brain and cognition in an age-dependent fashion, having generally beneficial effects on older animals and deleterious effects on younger...

Unique spatiotemporal fMRI dynamics in the awake mouse brain.

Current Biology February 7, 2022 Daniel Gutierrez-Barragan, Neha Atulkumar Singh, Filomena Grazia Alvino et al.

Human imaging studies have shown that spontaneous brain activity exhibits stereotypic spatiotemporal reorganization in awake, conscious conditions with respect to minimally conscious states. However, whether and how this phenomenon can be generalized to lower mammalian species remains unclear. Leveraging a robust protocol for resting-state fMRI (rsfMRI) mapping in non-anesthetized, head-fixed...
