Duke-led simulations show skull‑conforming flexible ultrasound arrays sharpen subcortical tFUS targeting

A Duke University simulation study (npj Acoustics, 30 Mar 2026) finds skull‑conforming flexible ultrasound arrays can produce smaller foci, higher peak pressure and lower sidelobes than a semi‑spherical array for ~4 cm subcortical targets; results come from MRI‑derived head models and are computational only.

Lantern-shaped ventricular BCI records stable deep-brain signals and decodes rat memory with 98% accuracy

A Tsinghua University team placed an expandable, lantern‑shaped electrode inside the lateral ventricle. In rats the ventricular BCI recorded stable signals for up to six months and decoded memory‑guided T‑maze choices with up to 98% accuracy.

Cortical beta rhythms encode motor and uncertainty signals; beta‑frequency rTMS shortens reaction time

A 2026 EEG‑rTMS study in 24 adults shows cortical beta oscillations separately encode uncertainty and movement preparation, and that beta‑frequency rTMS—especially when started at the beta trough—shortens reaction times and reduces beta desynchronisation.

Evidence-based decision tool for deep brain stimulation found acceptable by Parkinson’s patients

Neurology researchers published an evidence-based decision tool for deep brain stimulation on Mar 27, 2026; Parkinson’s patients in the report found the tool acceptable and rated its quality positively. The announcement did not include sample size or detailed outcome metrics and called for further evaluation.

Texas A&M builds digital human to detect early dementia through apathy screening

Texas A&M researchers are developing an AI "digital human" that asks screening questions and analyzes facial expressions and biometrics to generate a "Digital Apathy Signature" aimed at improving early dementia detection.

Columbia researcher wins grant to test rTMS on brain circuit linked to restrictive eating

Columbia psychologist Alexandra Muratore received the GFED Young Investigator Award to fund rTMS studies probing a brain circuit linked to restrictive eating in anorexia nervosa. The project will test whether non‑invasive magnetic stimulation changes symptoms and could inform mechanism‑based treatments.

Polydopamine-doped PEDOT coatings lower electrode impedance and strengthen cell–electrode contact

Sharif University researchers report a polydopamine-doped PEDOT coating that cuts 1 kHz impedance to ~270 Ω, makes the surface superhydrophilic, and increases cell adhesion in vitro; molecular dynamics show stronger membrane binding for PDA-containing interfaces.

Neurovascular impulse response function reflects region-specific neuromodulation across mouse cortex

Boston University researchers show that the neurovascular impulse response linking neural activity to blood volume varies across cortical regions in mice and reflects local neuromodulatory signals; data and code are publicly available on DANDI and GitHub.

USC-led ENIGMA study finds contralesional 'youthful' brain patterns linked to severe motor impairment after stroke

A multicohort ENIGMA study published in The Lancet Digital Health finds that large strokes speed aging in damaged tissue while making contralesional frontoparietal regions appear younger; the pattern correlates with severe, persistent motor deficits and may reflect compensatory neuroplasticity.

Mouse study links early‑adult stress‑drinking to locus coeruleus dysfunction and midlife cognitive decline

A mouse study in Alcohol Clinical & Experimental Research finds that drinking to cope with stress in early adulthood produced lasting locus coeruleus dysfunction, higher oxidative stress, and midlife cognitive deficits in mice; human implications remain unproven.
