The central role of the Thalamus in psychosis, lessons from neurodegenerative diseases and psychedelics.

Translational Psychiatry December 13, 2023 Marco Onofrj, Mirella Russo, Stefano Delli Pizzi et al. 42 citations

The PD-DLB psychosis complex found in Parkinson's disease (PD) and Dementia with Lewy Bodies (DLB) includes hallucinations, Somatic Symptom/Functional Disorders, and delusions. These disorders exhibit similar presentation patterns and progression. Mechanisms at the root of these symptoms also share similarities with processes promoting altered states of consciousness found in Rapid Eye Movement...

Sparse Bayesian modeling of hierarchical independent component analysis: Reliable estimation of individual differences in brain networks.

Biometrics December 2023 Joshua Lukemire, Giuseppe Pagnoni, Ying Guo

Independent component analysis (ICA) is one of the leading approaches for studying brain functional networks. There is increasing interest in neuroscience studies to investigate individual differences in brain networks and their association with demographic characteristics and clinical outcomes. In this work, we develop a sparse Bayesian group hierarchical ICA model that offers significant...

Inside the mindful moment: The effects of brief mindfulness practice on large-scale network organization and intimate partner aggression.

Cognitive, Affective, & Behavioral Neuroscience December 1, 2023 Hadley Rahrig, Liangsuo Ma, Kirk Warren Brown et al.

Mindfulness can produce neuroplastic changes that support adaptive cognitive and emotional functioning. Recently interest in single-exercise mindfulness instruction has grown considerably because of the advent of mobile health technology. Accordingly, the current study sought to extend neural models of mindfulness by investigating transient states of mindfulness during single-dose exposure to...

Positive Neuroscience: Comparing the Neural Correlates of Meditation and Creative Flow

Journal of Student Research November 30, 2023 Lisa D. Ordóñez 1 citation

Positive neuroscience focuses on the flourishing and optimized human brain. Despite this optimization being a result of higher conscious states, often caused by meditation or creative flow, the neuroscience field lacks research comparing these two unique brain states. Therefore, through an exploratory content analysis, this research will reveal what neural mechanisms can potentially...

Current Understanding on Psilocybin for Major Depressive Disorder: A Review Focusing on Clinical Trials

Clinical Psychopharmacology and Neuroscience November 30, 2023 Sunghwan Kim, Won-Seok Choi, Hyun Kook Lim et al. 16 citations

Previous studies suggested effectiveness of psilocybin in the field of mental health. FDA designated psilocybin as a "breakthrough therapy" for the treatment of treatment-resistant depression (TRD) in 2018. This paper provided a review of psilocybin's potential role in treatment of depression by focusing on published clinical trials. Studies showed that psilocybin, an agonist on 5-HT2A...

The neural signature of inner peace: morphometric differences between high and low accepters

arXiv Preprint Archive October 20, 2023 Alessandro Grecucci, Parisa Ahmadi Ghomroudi, Bianca Monachesi et al. preprint

Acceptance is an adaptive emotion regulation strategy characterized by an open and non-judgmental attitude toward mental and sensory experiences. While a few studies have investigated the neural correlates of acceptance in task-based fMRI studies, a gap remains in the scientific literature in dispositional use of acceptance, and how this is sedimented at a structural level. Therefore, the aim...

Special Subsection Afterword: ESP Research and Cognitive Neuroscience: Possibly Incompatible - But Methodologically Complementary

Journal of Scientific Exploration October 19, 2023 David J Acunzo 1 citation

This commentary considers the fields of extrasensory perception (ESP) research and cognitive neuroscience, discussing points of conflict and domains where they may be complementary. ESP research challenges the assumption in cognitive neuroscience that the mind is the product of known physical processes in the brain. Cognitive neuroscience methods and tools applied to ESP research could benefit...

Leyi Mental Training: Bridging Ancient Wisdom and Modern Science to Reduce Anxiety via Altered Brain Dynamics

Journal of Artificial Intelligence & Cloud Computing October 10, 2023 Xiaofei Jia, Changle Zhou

Leyi is a set of physical and mental cultivation methods established by Professor Changle Zhou after many years of practice. It combines modern psychological adjustment and Chinese ancient Buddhist practice methods, including relaxation, breathing, meditation, koan, and cognitive regulation. Its purpose is to achieve the state of enlightenment (a high-level ideology in Buddhism). More than ten...

Brain functional connectivity of hypnosis without target suggestion. An intrinsic hypnosis rs-fMRI study

The World Journal of Biological Psychiatry October 3, 2023 Pablo G. Vázquez, Susan Whitfield, Clemens C C Bauer et al. 8 citations

Objective During hypnosis, significant changes in the BOLD signal associated with the anterior default mode network (DMN) and prefrontal attentional systems have been reported as evidence of dissociation defined since Charcot. However, it remains uncertain whether these changes are mainly attributable to the hypnotic state per se or to the target suggestions used to verify subject's state...

Persistent Brain Connectivity Changes in Healthy Volunteers Following Nitrous Oxide Inhalation.

Biological Psychiatry Global Open Science October 1, 2023 Ben Julian A Palanca, Charles R Conway, Thomas Zeffiro et al.

Nitrous oxide holds promise in the treatment of major depressive disorder. Its psychotropic effects and NMDA receptor antagonism have led to comparisons with ketamine. Despite longstanding use, persistent effects of nitrous oxide on the brain have not been characterized. Sixteen healthy volunteers were recruited in a double-blind crossover study. In randomized order, individuals underwent a...
