Conventional antidepressants show moderate efficacy in treating major depressive disorder. Psychedelic-assisted therapy holds promise, yet individual responses vary, underscoring the need for predictive tools to guide treatment selection. Here, we present graphTRIP (graph-based Treatment Response Interpretability and Prediction) - a geometric deep learning a...
The phenomenology of psychedelic experiences has been a long-standing point of interest to researchers. However, internal experience has been relatively relegated, with much work done on the clinical outcomes of psychedelic therapies. Our reflexive thematic analysis revealed that structurally, people on fora write about their experiences sequentially, consid...
BACKGROUND: Military veterans are at risk of various mental health conditions, with profound implications for post-deployment quality of life. Current treatment options encounter high dropout rates and non-responsiveness, and overlook the importance of community building in veterans' holistic recovery. Preliminary research suggests psychedelics offer therape...
Research on psychedelic drugs, such as psilocybin, LSD or DMT, is a burgeoning field, with an increasing number of studies showing their promise in treatment of mental disorders as well as examining their mechanism of action. Determining their effect on the brain is crucial from clinical standpoint, but also offers highly promising avenues of advancement in ...
Parkinson’s Disease (PD) is a progressive neurodegenerative disorder marked by motor symptoms due to dopaminergic degeneration and non-motor symptoms such as depression, anxiety, and cognitive impairment, which significantly affect patients' quality of life. Traditional dopaminergic therapies address motor symptoms but offer limited efficacy for neuropsychia...
The prospective pilot study will address the critical need for more precise characterizations of the acute visual effects of the drug psilocybin by measuring the impact of acute psilocybin intoxication on a perceptual task known as visual surround suppression, compared to an active placebo control. The proposed pilot study will address the critical need for ...
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 tha...
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 incre...
Abstract This 33-month retrospective case report explores the impact of psilocybin truffle intake on the emergence (and persistence) of mental imagery in an autistic woman with aphantasia. Aphantasia refers to the inability to generate visual mental images, which can significantly affect individuals' experiences and cognitive processes. The case study focuse...
Depression and anxiety are disabling and high incidence mental disorders characterized by phenotypic heterogeneity. Currently available treatments show severe limitations. Thus, there is an urgent need for effective treatments in this population. In the search for novel rapid-acting antidepressants, the psychedelic psilocybin has emerged as a promising thera...
This is an open-label, single-arm, pilot study exploring the neural, sensory, and cognitive effects of a single, medium dose of psilocybin in patients with chronic pain who already have implanted sensing-capable deep brain stimulation (DBS) devices. Outcomes include multi-site neural recording from previously placed ambulatory sensing-capable DBS devices, qu...
Human neuroimaging with functional Magnetic Resonance Imaging has been a key feature of the current wave of psychedelic research, in both healthy and clinical populations. The available data has suggested that classic psychedelics (psilocybin, LSD, DMT) have a characteristic effect of acutely and profoundly disrupting the normal pattern of resting-state conn...
Psilocybin (PSIL) is a psychedelic drug and a promising experimental therapeutic for many psychiatric conditions. Precision functional mapping (PFM) combines densely repeated resting state fMRI sampling and individual-specific network mapping to improve signal-to-noise ratio (SNR) and effect size in brain imaging research. We present a randomized cross-over ...
Psychedelics, such as LSD and psilocybin, disrupt entrenched cognitive patterns by facilitating novel insights and new associations. This paper considers how AI can potentially mimic these psychedelic-induced cognitive disruptions to augment and enhance human creativity. Psychedelics likely enhance creativity by altering brain function, notably the activity ...
Neurological and psychiatric disorders are considered one of the major problems of today's societies and cause many individual and social problems. Current treatments are effective, but due to their burdens, there is always an effort to introduce novel treatments. Psychedelics, a diverse group of psychoactive compounds, including LSD, psilocybin, DMT, MDMA, ...
Dr. Erin E. Mauney serves as Assistant Professor of Pediatrics (Gastroenterology) at Tufts University while maintaining a research appointment at Massachusetts General Hospital. With dual board certification, including obesity medicine, she integrates clinical expertise with innovative research at the intersection of gut-brain disorders and psychedelic medic...
Several species of fungi, collectively known as 'psychedelic fungi', produce a range of psychoactive substances, such as psilocybin, ibotenic acid, muscimol and lysergic acid amides. These substances interact with neurotransmitter receptors in the human brain to induce profound psychological effects. These substances are found across multiple fungal phyla, i...
Psilocybin is a psychedelic serotonergic compound that is renowned for its potent psychoactive effects. Over the past 15 years, an increasing number of controlled clinical trials showed that it has a fast-acting and sustainable efficacy in treating various psychiatric disorders. Neuroimaging studies have been conducted with the objective of elucidating the n...
