Abstract This paper presents Wireless Wearable Myolink (W2 Myolink), a high-density, battery-powered system for wireless acquisition of surface electromyography(EMG) signals, and demonstrates its practicality across diverse experimentalparadigms. The device features a compact form factor (110x70x35 mm), low weight(160 g), and continuous operation for up to 6...
Abstract Rationale and Objectives: Polysubstance use involving psychostimulants and opioids is increasingly prevalent and associated with elevated overdose risk, relapse vulnerability, and poor treatment outcomes. However, the neurobehavioral consequences of opioid-stimulant use remain poorly understood. We evaluated whether repeated methamphetamine-fentanyl...
This is a proof-of-concept randomized clinical trial of psilocybin-enhanced psychotherapy versus treatment-as-usual among individuals being treated for methamphetamine use disorder. The trial will take place with individuals admitted to a residential rehabilitation treatment program. The treatment protocol will consist of 4 preparatory therapy visits, 2 psil...
This article proposes a research agenda for psilocybin-assisted therapy focusing on the correlation between neural entropy and long-term cognitive flexibility.
Abstract Rationale Clinical interest in psilocybin-assisted rehabilitation for motor disorders is growing. However, psilocybin’s motor effects are under-researched, and quantifying them is essential for assessing treatment risks and outcomes. Objectives This study aims to clarify whether acute effects of psilocybin disrupts established patterns of manual dex...
Altered states of consciousness (ASC) represent a universal human capacity for accessing and transforming the subconscious mind, employed across cultures and millennia through diverse contemplative, somatic, pharmacological, ritual, and technological modalities. This comprehensive review synthesizes evidence from over 25 distinct disciplines spanning five cl...
Abstract Depression and anxiety affect one in five adults, with age affecting prevalence. While clinical trials suggest classic psychedelics (e.g., psilocybin, LSD) and non-classic psychedelics (e.g., MDMA, ketamine) may alleviate these symptoms, it remains unclear how these relationships function in naturalistic settings or how they vary across the lifespan...
Abstract Background: This case describes a substance-induced manic episode with psychotic features in which interaction with an AI (artificial intelligence) chatbot appeared to corroborate and reinforce the patient’s delusional thought content and to contradict medical advice. Excerpts from the patient’s interactions with the AI chatbot provide novel clinica...
Intestinal inflammation is a complex gastrointestinal condition, arising from immune dysfunction, epithelial cell abnormalities, and gut microbiota imbalances. Intestinal inflammation contributes to many pathological conditions, including irritable bowel disease and depression. This study seeks to find the potential anti-inflammatory properties of psilocybin...
This paper follows 8 scientists who ventured into the world of psychedelics on a quest to find transformational pathways forward. Each have worked on aspects of global environmental change for decades, and observing environmental crises converging into a global polycrisis/metacrisis with genuine potential for collapse, we have all carried psychological burde...
Abstract Repeated mild traumatic brain injury (RmTBI) can produce lasting cognitive, emotional, and social deficits (e.g., persistent post-concussion symptoms; PPCS). Despite the prevalence of RmTBI in sports, military, and domestic violence settings, effective treatments to alleviate the neurological consequences of RmTBI remain limited. Psilocybin, a serot...
Abstract IMPORTANCE Microdosing psilocybin may be a novel treatment for major depressive disorder (MDD). OBJECTIVE Assessing the antidepressant effects and safety of repeated low doses of psilocybin in participants diagnosed with MDD. DESIGN This was a Phase II, randomized, double-blind, placebo-controlled clinical trial. SETTING The trial was conducted from...
People with cancer often experience anxiety and depression following a diagnosis and can face barriers to accessing treatment for their mental health. An increasing number of patients are considering alternative approaches to managing their mental health symptoms, such as the psychedelic, psilocybin. A growing number of clinical trials show significant and e...
Abstract Rapid-acting antidepressants like ketamine and serotonergic psychedelics show promise for treatment-resistant depression (TRD), but the molecular mechanisms that contribute to their therapeutic effects remain unclear. Induced pluripotent stem cells (iPSCs) offer a platform to model human cortical neurons and investigate drug effects in a human-relev...
Psychedelic compounds, particularly psilocybin, have demonstrated remarkable therapeutic potential for mental health disorders through mechanisms involving structural neural plasticity. This comprehensive review examines recent breakthrough research revealing how psilocybin triggers activity-dependent rewiring of large-scale cortical networks. Using monosyna...
Recent advances in neuroscience have revealed unprecedented insights into how psilocybin, the psychoactive compound in magic mushrooms, induces therapeutic neural plasticity. This paper reviews groundbreaking research conducted by Cornell University and the Allen Institute for Brain Science, which employed genetically modified rabies virus for monosynaptic c...
Abstract Large language models (LLMs) are increasingly consulted by individuals for support during psychedelic experiences ("trip sitting"), yet no framework exists to evaluate whether these models can accurately simulate or safely respond to altered states of consciousness. We aimed to determine if LLMs can be induced to generate narratives resembling human...
Psilocybin is a psychoactive tryptamine produced by a phylogenetically discontinuous yet ecologically diverse subset of fungi. Despite decades of chemical, pharmacological, and ethnobiological research, the evolutionary forces driving the emergence and persistence of this compound remain insufficiently explained. Recent hypotheses proposing that psilocybin e...
About 30-50% of patients with advanced illness experience depression, anxiety, or decreased sense of purpose and autonomy. Together, these are called psychological distress. Treatment options such as medication and therapy are available; however, they do not always work and can be time-consuming and expensive. We need treatments that work well, quickly, and ...
