MoS2 Artificial Neurons Triggered Responses in Living Brain Slices

by
MoS2 Artificial Neurons Triggered Responses in Living Brain Slices

TL;DR: A 2026 study in Nature Nanotechnology reported that printed MoS2 memristive nanosheet networks, electronic devices that can produce neuron-like spikes, triggered responses in living mouse brain slices. Key Findings Artificial spiking neurons: Researchers built printed MoS2 memristive nanosheet networks that generated electrical activity resembling neural spikes. Living-tissue response: In mouse brain-slice experiments, the artificial …

PTP1B Inhibition Reduced Amyloid-Beta in Alzheimer’s Mice

by
PTP1B Inhibition Reduced Amyloid-Beta in Alzheimer's Mice

TL;DR: A 2026 mouse study in Proceedings of the National Academy of Sciences found that deleting or inhibiting PTP1B improved memory behavior, reduced amyloid-beta burden, and pushed microglia toward an amyloid-clearing state. Key Findings Memory behavior improved: APP/PS1 mice lacking PTP1B performed better in novel object recognition and Morris water maze tests; the PTP1B inhibitor …

Prior Headaches Quadrupled Dialysis Headache Odds in Hemodialysis Patients

TL;DR: A 2026 study in Journal of Pain Research found dialysis headache in 50.6% of 79 adults receiving maintenance hemodialysis, with prior recurrent headaches and female sex independently linked to higher odds of developing headaches during dialysis. Key Findings 79 hemodialysis patients: Researchers interviewed adults with end-stage renal disease who had been on regular hemodialysis …

Math-Music Link Nearly Vanished After Accounting for Intelligence

TL;DR: A 2026 Journal of Intelligence study of 170 adults found that math ability and music ability were only weakly related, and the link was reduced to almost zero after researchers accounted for general intelligence. Key Findings Adult ability groups were tested: The 170-person sample included math specialists, music specialists, and controls who did not …

Emotional Memory fMRI Separated Arousal From Valence Effects

by
Emotional Memory fMRI Separated Arousal From Valence Effects

TL;DR: A 2026 Imaging Neuroscience functional MRI (fMRI) study found that emotional pictures were recalled better than neutral pictures, but amygdala and insula activity appeared tied mainly to arousal rather than whether memories were negative or positive. Key Findings Large fMRI sample: The main imaging analysis used 1,006 healthy young adults from a single center. …

Inaudible Infrasound Increased Stress Hormones and Negative Mood in Controlled Trial

by
Inaudible Infrasound Increased Stress Hormones and Negative Mood in Controlled Trial

TL;DR: A 2026 Frontiers in Behavioral Neuroscience study reported that inaudible infrasound shifted mood toward unease and raised stress-hormone markers under controlled conditions, offering a physiological explanation for some room-specific fear sensations without supporting supernatural claims. Key Findings Inaudible infrasound shifted mood: Controlled exposure produced measurable mood changes — toward unease, anxiety, and a felt …

Loneliness-Isolation Mismatch Predicted Cognition Through Chronic Disease

by
Loneliness-Isolation Mismatch Predicted Cognition Through Chronic Disease

TL;DR: A 2026 MIDUS mediation study in Brain, Behavior, & Immunity – Health found that social asymmetry was associated with greater chronic disease burden, while chronic disease burden mediated links between social asymmetry and episodic memory and executive function, while allostatic load did not. Key Findings Study type: a structural equation modeling study of social …

Lateral Septal PACAP Signaling Regulated Stress and Anxiety Responses

by
Lateral Septal PACAP Signaling Regulated Stress and Anxiety Responses

TL;DR: A 2026 rat study in Neuropsychopharmacology found that PACAP/PAC1 signaling in the lateral septum changed forced-swim coping, ACTH stress-hormone release, open-arm exploration, and grooming behavior. Key Findings Stress changed PACAP signals by brain region: Acute swim stress increased PACAP mRNA in the lateral septum, BNST, and basolateral amygdala, while chronic variable mild stress reduced …

Quantitative MRI Detected White Matter Injury Linked to MoCA Scores

by
Quantitative MRI Detected White Matter Injury Linked to MoCA Scores

TL;DR: A 2026 medRxiv preprint used quantitative multi-parametric MRI mapping in 245 BeLOVE participants and found that white matter hyperintensities had lower MTsat and R1 plus higher proton density, with nearby normal-appearing white matter also showing microstructural changes linked to MoCA, a brief cognitive screening score. Key Findings 245 MRI participants: The analysis used cerebral …

Late-Window Stroke IVT Did Not Improve Thrombectomy Outcomes

by
Late-Window Stroke IVT Did Not Improve Thrombectomy Outcomes

TL;DR: A 2026 medRxiv preprint found that giving intravenous thrombolysis (IVT), a clot-dissolving drug treatment, before endovascular thrombectomy (EVT), a catheter procedure to remove a large brain clot, did not significantly improve 3-month recovery or increase bleeding risk in selected stroke patients treated 6 to 24 hours after symptoms began. Key Findings Registry cohort: The …
