Introduction Many Veterans who experienced blast-related traumatic brain injuries (TBIs) in Iraq and Afghanistan currently suffer from chronic cognitive and mental health problems that include depression and post-traumatic stress disorder (PTSD). Male rats exposed to repetitive low-level blast develop chronic cognitive and PTSD-related behavioral traits that are present for more than 1 year...

The use of drugs with psychedelic and dissociative effects for the treatment of psychiatric illnesses has become increasingly popular in recent years. However, few trials have been conducted to determine the efficacy of these agents in the specific setting of treatment-resistant major depressive disorder (MDD) in older adults. In this paper, we review notable aspects of treatment-resistant MDD...
Foundation models are transforming neuroscience but are often prohibitively large, data-hungry, and difficult to deploy. Here, we introduce BrainSymphony, a lightweight and parameter-efficient foundation model with plug-and-play integration of fMRI time series and diffusion-derived structural connectivity, allowing unimodal or multimodal training and deployment without architectural changes...
Psychedelic-assisted psychotherapy (PAP) constitutes a novel treatment paradigm in mental health care practice that is currently being evaluated for its clinical efficacy and safety. Insight into the attitudes of clinicians toward PAP remains crucial for its successful integration into mental health care. This cross-sectional survey explores the attitudes of Dutch mental health care...
Serotonergic psychedelic drugs are under investigation as therapies for various psychiatric disorders, including major depression. Although serotonergic psychedelic drugs are 5-HT2A receptor agonists, some such agonists are not psychedelic, potentially due to differences in 5-HT2A receptor ligand bias or signalling efficacy. Here, we investigated 5-HT2A receptor signalling properties of...
In this study, we provide the first study to integrate molecular and functional neuroimaging during psychedelic drug effects in humans. Using simultaneous PET-MRI technology, we describe multiple brain actions of lysergic acid diethylamide (LSD) in healthy volunteers. We quantify the occupancy of LSD at cerebral serotonin 2A receptors and show that LSD increases global cerebral blood flow and...
Background Ketamine exerts potent but transient antidepressant effects in treatment-resistant depression (TRD). Combinations of ketamine and psychotherapy have attracted interest, but no trial has investigated a psychedelic model of ketamine–psychotherapy for TRD to our knowledge. Aims This secondary analysis of a randomised clinical trial (RCT) explores the therapeutic effects and experiential...
Phosphorylation plays important roles in biology by modulating the structure, reactivity, and biological function of a broad range of molecules. Biocatalytic phosphorylation has attracted attention from synthetic chemists due to its selectivity and mild reaction conditions using ATP as a phosphate donor. Given the potential synthetic utility of kinases with activity on small molecule...
The chapter presents an intercultural dialogue of knowledge production regarding psilocybin mushroom use among the Mazatec, a highly significant entheogenic practice of Mexico. The Chota Chjine, the wise ones, use Psilocybe mushrooms to mediate connections with the world of spirits to determine what disruptions of balance have led to illness and how to restore health and well-being. The Chjota...
This chapter examines the use of psilocybin mushrooms (known as teonanacatl or “the flesh of gods”) and Mexican tarragon (yauhtli, Tagetes lucida) for therapeutic purposes in Nahua medicine. These entheogenic substances are associated with thunderbolt and rain deities, part of a symbolic complex known as “the healing of the thunderbolt,” reflecting the influence of Tlaloc, the god of rain and...
