TL;DR: A 2026 study in The Journal of the Acoustical Society of America found that seeing a video tied to the sound source, such as motion from a train, drum, keyboard, bird, or canoe paddle, made faint sounds easier to detect through noise. Closing the eyes raised sound-detection thresholds by 1.32 dB, while videos tied …
TL;DR: A 2026 preprint in medRxiv reported that REDDI, an interpretable AI pipeline using resting-state magnetoencephalography (MEG), classified four neurodegenerative diseases with mean balanced accuracy of 0.81. Key Findings The dataset covered four disease groups: it included 32 people with mild cognitive impairment, 18 with multiple sclerosis, 20 with Parkinson’s disease, and 39 with amyotrophic …
TL;DR: A 2026 study in Brain found that creativity in behavioral variant frontotemporal dementia tracked a rostral prefrontal cortex gradient, meaning the functional separation between default-mode and executive-control networks predicted creative performance. Key Findings 56-person clinical sample: researchers compared 27 patients with behavioral variant frontotemporal dementia (bvFTD) against 29 control participants from the ECOCAPTURE cohort. …
TL;DR: A 2026 trial in Journal of Psychopharmacology found that repeated supervised psilocybin sessions reduced Yale-Brown Obsessive Compulsive Scale (YBOCS) scores, a standard measure of obsession and compulsion severity, in 15 adults with OCD. Key Findings 73.3% met responder criteria: At the end of the 8-week treatment, 11 of 15 participants had at least a …
TL;DR: A 2026 mixed-methods study in BMC Psychiatry found that adults in psychiatric treatment valued group-based physical activity less as generic exercise and more as structured, socially supported care, with 97% of questionnaire participants saying they felt supported by activity leaders. Key Findings Real-world psychiatric care: The program was embedded in an Oslo outpatient clinic …
TL;DR: A 2026 study in Signal Transduction and Targeted Therapy built a Parkinson’s visual hallucination mouse model and found that a combined behavior map identified hallucination-like episodes better than any single movement measure. Key Findings Model: Researchers used 6-OHDA to create Parkinson-like dopamine injury in male C57BL/6 mice, then used benzhexol hydrochloride to trigger Parkinson’s …
TL;DR: A 2026 preprint in medRxiv found that deep brain stimulation for severe obsessive-compulsive disorder was followed by lower globus pallidus externus alpha-band activity in clinically responsive patients, suggesting a possible brain readout of sustained DBS response. Key Findings 10 severe OCD patients: Researchers recorded local field potentials from the anterior globus pallidus externus (GPe) …
TL;DR: A 2026 mouse study in The Journal of Physiology found that damaging noise temporarily disrupted sound-offset responses in a brainstem hearing circuit, but those timing responses partly recovered within 24 hours through rapid circuit adaptation. Key Findings Sound-offset responses mark when sound ends: researchers studied neurons in the superior paraolivary nucleus (SPN), a brainstem …
TL;DR: A 2026 study in The British Journal of Psychiatry found that a single 50 mg dose of naltrexone reduced distress and shifted threat-related brain activity without blocking people’s ability to reappraise negative images. Key Findings 38 healthy volunteers completed a placebo-controlled crossover: Participants received naltrexone 50 mg and placebo on separate visits, then performed …
TL;DR: A 2026 Molecular Psychiatry study tested Regional Vulnerability Index for Alzheimer’s disease (RVI-AD), a structural-MRI score of how closely a person’s brain pattern resembles amyloid-positive Alzheimer’s disease, and found that higher RVI-AD predicted conversion from mild cognitive impairment to dementia most strongly in the first 3 years. Key Findings 571-person reference map: Researchers built …
