TL;DR: A 2026 randomized trial in Journal of Medical Internet Research gave adults with elevated depression symptoms the same coach-led group skills program through either a VR headset or a flat screen. Depression scores fell slightly faster in the VR group over 8 weeks. Key Findings The VR group improved a little faster: Depression scores …
TL;DR: A 2026 medRxiv preprint found that pupil dilation measured inside a virtual reality (VR) headset increased as working-memory load rose in healthy adults, was reproducible 60–90 days later in 33 returnees, and was smaller under the highest load in cognitively impaired patient cohorts than in 81 healthy controls. Key Findings Forty-three healthy adults completed …
TL;DR: A 2026 randomized training study in Nature Communications found that sensory-guided joint learning—a combination of performance-triggered wrist vibration, Copy/New strategy cues, and an adaptive electroencephalography (EEG) decoder—produced a 19.0-percentage-point improvement in motor-imagery brain-computer interface (BCI) accuracy in healthy BCI-naĂŻve adults, versus 6.3 and 3.0 points in two control groups. Key Findings Thirty-one healthy adults …
TL;DR: A 2026 mouse study in Nature Communications reported that 10 daily bouts of optogenetic dentate-gyrus stimulation produced weeks-long changes in chromatin, nuclear structure, behavior, and spatial coding, while Cyclin B deletion weakened several effects; this ECT-inspired model does not establish how electroconvulsive therapy works in people. Key Findings Ten stimulation sessions produced the durable …
TL;DR: A 2026 randomized study in Psychological Medicine reported that 7–10 days of prucalopride improved word-learning recall and working-memory response speed versus placebo in adults with remitted recurrent depression, but the 49-person analysis did not test durability, daily functioning, or relapse prevention. Key Findings Short randomized exposure: Researchers analyzed 49 adults ages 18–40 after 7–10 …
TL;DR: A 2026 mouse study in Communications Biology found that loss of MGAT5B, a brain-enriched enzyme that branches O-mannose sugars on proteins, widened nodes of Ranvier—the intervals between myelin segments that organize axon signaling—and delayed callosal spike timing. Neuron-targeted MGAT5B shifted pooled node widths lower, but the rescue compared only 2 treated with 3 control …
TL;DR: A 2026 study in Science Advances reported that disrupting the membrane-associated periodic skeleton (MPS), an actin-spectrin lattice beneath neuron membranes, reduced the fitted amyloid precursor protein (APP) uptake time constant in cultured mouse hippocampal neurons and increased intracellular amyloid-beta 42 under APP-overexpression conditions. The cell-culture experiments do not show that stabilizing the MPS prevents …
TL;DR: A 2026 mouse study in Gene Therapy used an adeno-associated virus 9 (AAV9) vector to deliver human FMR1 and reduced sound-triggered seizures, excessive digging, and gamma-frequency electroencephalography (EEG) power in selected dose and route groups. The outcomes came from separate experiments, and high-dose intravenous treatment without immunosuppression caused excess deaths. Key Findings Adolescent seizure …
TL;DR: A 2026 mixed-methods study in Evolutionary Psychological Science found that 621 Greek-speaking adults rated emotional motives for lasting relationships—such as attraction, love, companionship, and support—much higher than instrumental motives such as money, social pressure, or revenge (3.30 vs 1.39 on a five-point scale). The convenience-sample survey describes stated motivations, not what causes relationships to …
TL;DR: A 2026 Phase 2 trial in The British Journal of Psychiatry found that 10 mg emestedastat did not improve attention and working memory after six weeks in adults with major depressive disorder and objectively measured cognitive impairment. A nominal depression-score difference appeared four weeks after treatment ended, but it was secondary, unadjusted for multiple …
