Bridging Psychedelic VR and BCI: Enhancing User Experience through Adaptive EEG-Guided Neural Modulation

International Conference on Tangible, Embedded, and Embodied Interaction March 4, 2025 Leon Lange, Jacob Yenney, Y. C. Wu

Virtual reality (VR) and psychedelic experiences share significant phenomenological and therapeutic parallels, both offering immersive environments capable of altering perception and evoking profound emotional responses. This study explores the integration of VR with simulated psychedelic experiences using brain-computer interface (BCI) systems to harness their combined therapeutic potential....

Low-dose ketamine improved brain network integrity among patients with treatment-resistant depression and suicidal ideation.

Psychiatry Research March 1, 2025 Tung-Ping Su, Li-Kai Cheng, Pei-Chi Tu et al. 6 citations

Ketamine is a dissociative drug used for the treatment of depression. However, the neurofunctional mechanism underlying the antidepressant effect of ketamine remains unknown. According to previous research, low-dose ketamine affects large-scale brain networks, including default-mode and salient networks. A total of 43 patients with treatment-resistant depression (TRD) and suicidal ideation (SI)...

Brain connectivity correlates of the impact of a digital intervention for individuals with subjective cognitive decline on depression and IL-18.

Scientific Reports February 26, 2025 Merav Catalogna, Ya'Ira Somerville, Nira Saporta et al. 6 citations

Late-life depression represents a significant health concern, linked to disruptions in brain connectivity and immune functioning, mood regulation, and cognitive function. This pilot study explores a digital intervention targeting mental health, brain health, and immune functioning in individuals aged 55-60 with subjective cognitive decline, elevated stress and depressive symptoms. Seventeen...

Psychedelics as an alternative to traditional pharmacotherapy in treating mental disorders – a review of latest studies

Medical Science February 25, 2025 Jakub Pudźwa, Kamil Gibczyński, Karol Leśniewski et al.

Objective: The purpose of the following review was to summarize the recent studies on proposed mechanisms of action of psychedelic drugs (psilocybin, MDMA, LSD), their therapeutic potential in mental disorders (depression, PTSD, addictions), and the evaluation of their safety. This review also discusses the barriers to the clinical implementation of these agents. Methodology: The paper combines...

Ketamine-Assisted Psychotherapy for Generalized Anxiety Disorder: A Comprehensive Case Report with Integrated Neurophysiological Imaging Using Magnetoencephalography

medRxiv Preprint Server February 25, 2025 J Cohen, AC Reichelt, R Zamyadi et al. 1 citation preprint

This detailed case report explores the application of ketamine-assisted psychotherapy (KAP) in the treatment of a male patient in their late 30’s with Generalized Anxiety Disorder (GAD) and depressive symptoms. The N-methyl-D-aspartate (NMDA) receptor antagonist ketamine represents a significant breakthrough in the treatment of mood and anxiety disorders due to its rapid and robust...

Psychedelic-assisted Therapy as a Promising Treatment for Irritable Bowel Syndrome

Journal of Clinical Gastroenterology February 17, 2025 Erin Mauney, Franklin King, Helen Burton-Murray et al. 3 citations

Irritable bowel syndrome (IBS) is prevalent and can be disabling. Many patients remain symptomatic despite behavioral and medical therapies. Psychedelic-assisted therapy (PAT), in which serotonergic agents like psilocybin are administered in a psychotherapeutic context, has shown promise for refractory psychiatric disorders, including major depressive disorder and post-traumatic stress...

Dynamic functional connectivity signatures of focused attention on the breath in adolescents.

Cerebral Cortex February 5, 2025 Isaac N Treves, Aaron Kucyi, Anna O Tierney et al. 1 citation

Breathing meditation typically consists of directing attention toward breathing and redirecting attention when the mind wanders. As yet, we do not have a full understanding of the neural mechanisms of breath attention, in particular, how large-scale network interactions may be different between breath attention and rest and how these interactions may be modulated during periods of on-task and...

Enlightenment, a Distinct Cognitive State: Executive Awareness Cognition Theory (ExACT)

January 10, 2025 Navdeep Ahuja, Yogesh Singh, Jayvardhan Singh preprint

Enlightenment, which can be described as the end goal of long-term meditation practices, is a mental state where the boundaries of the apparent Self dissolve, experienced as a nondual awareness. The neural correlates of meditation reveal patterns such as deactivation of the Default Mode Network, activation of the Central Executive Network, and structural brain reorganization.In this context, we...

Processing of self-related thoughts in experienced users of classic psychedelics: A source localisation EEG study.

Progress in Neuro-Psychopharmacology and Biological Psychiatry January 10, 2025 Anastasia Ruban, Mikołaj Magnuski, Justyna Hobot et al. 1 citation

Psychedelics have gained increasing interest in scientific research due to their ability to induce profound alterations in perception, emotional processing and self-consciousness. However, the research regarding the functioning of individuals who use psychedelics in naturalistic contexts remains limited. Here we aim to explore psychological and neurophysiological differences between...

Network topology and cannabis use following two weeks of monitored abstinence: moderation of sex and patterns of use findings.

Frontiers in adolescent medicine 2025 Kyle A Baacke, Ryan M Sullivan, Chase A Shankula et al.

Chronic cannabis use (CU) can result in subtle deficits in cognitive performance that may be linked with alterations in underlying neural functioning. However, these network alterations are not well-characterized following monitored abstinence. Here, we evaluate differences in functional brain network activity associated with CU patterns in adolescents/young adults. Functional connectomes were...
