New Math Framework Reveals Hidden Brain Cycles in fMRI Data
Researchers introduced a variational framework that detects large-scale cyclic interactions in brain networks, uncovering stable patterns invisible to standard methods.
New Alzheimer's Trigger Found and Drug Candidate Stops It in Mice
Researchers at ETH Zurich identified a protein aggregate that triggers nerve cell death in Alzheimer's and developed an experimental compound that breaks the cycle in mice.
Outdoor Play in Preschool Boosts Children's Mental Health Long-Term
A new study of 4,151 children found that each additional day per week of outdoor play for ages 2–4 reduces the odds of mental health difficulties by up to 14% by age 8.
SSRIs Affect Two Distinct Serotonin Neuron Populations in Opposite Ways
New research reveals that SSRIs trigger opposite gene-expression changes in two distinct serotonin neuron groups, explaining why side effects precede therapeutic benefits.
Brain Stimulation Offsets Memory Loss from Sleep Deprivation
Researchers used optogenetics to induce sleep-like neural patterns in awake mice, completely reversing memory deficits from sleep deprivation.
Compound 10 Blocks Nerve Cell Death in Alzheimer’s by Preserving Mitochondrial Energy
A new compound prevents GRK2 protein aggregation, preserving mitochondrial function and slowing Alzheimer’s progression in mice.
VR Brain Training May Slow Cognitive Decline in Older Adults
A systematic review of randomized controlled trials finds that virtual reality-based cognitive training can help prevent cognitive decline in older adults with mild cognitive impairment.
How EEG Foundation Models Confuse Person Identity with Brain Signals
New research reveals that popular EEG AI models often rely on subject identity rather than actual brain signals, potentially misleading clinical diagnoses.
Brain-Targeted Estrogen Drug Reverses Cognitive Decline from Cancer Therapy
A brain-selective estrogen prodrug called DHED reversed memory and sleep deficits in marmosets without increasing cancer risk, offering hope for breast cancer patients.
Female Brain Uses Unique Molecular Tag to Form Fear Memories, Study Finds
New research reveals that the female brain relies on a distinct molecular tag, K27 polyubiquitination, to store fear memories—a process absent in males, offering a biological clue to PTSD's higher prevalence in women.
Flu Drugs May Slow Cognitive Decline in Chronic Viral Infections
A Northwestern University study suggests that sialidase inhibitors like Tamiflu can preserve protective glycans, reducing inflammation and cognitive decline in HIV patients.
Microglial State Tipping Point in Alzheimer's Disease Resilience
Researchers identify a critical microglial state transition that acts as a tipping point for Alzheimer's dementia, with two distinct resilience pathways in octogenarians and centenarians.
