Frequent TV Watching Linked to Increased Brain Lesion Volume

A 24-year analysis of 1,712 adults from the Atherosclerosis Risk in Communities (ARIC) study reveals that the impact of sedentary behavior on brain health depends heavily on the activity performed. Research published in the journal Alzheimer’s & Dementia indicates that while television watching is associated with reduced brain volumes and increased vascular markers, occupational sitting … Read more

Tau Buildup in PSP Disrupts Brain Networks and Cognitive Function

Progressive supranuclear palsy (PSP) symptoms, including cognitive decline, may stem from remote brain network disruptions rather than just local tau protein accumulation. Research published in Science Advances by the National Institutes for Quantum Science and Technology (QST) indicates that tau deposits in deep brain regions can impair distant cortical areas, such as the prefrontal cortex, … Read more

Longer Hormone Exposure Linked to Healthier Brain Aging in Women

Women who have used hormonal birth control or menopausal hormone therapy (MHT) show structural brain differences associated with healthier aging, according to research published in the journal NeuroImage. A study of 459 women aged 65 to 80 found that lifetime exposure to these hormones correlates with greater gray matter volume and cortical thickness in brain … Read more

Electroacupuncture at Lianquan Point for Post-Stroke Dysphagia Recovery

Researchers at Guangzhou University of Chinese Medicine have identified the hypoglossal nucleus (12N) as the primary brainstem motor node responsible for the swallowing improvements observed after electroacupuncture at the “Lianquan” (CV23) acupoint. Published in Acupuncture Research on August 25, 2025 (DOI: 10.13702/j.1000-0607.20250444), the study confirms that this neural pathway is essential for restoring swallowing function … Read more

How Psychological Traits Influence Alzheimer’s Biology

Long-standing psychological traits, including neuroticism and a lack of purpose, track distinct molecular pathways in Alzheimer’s dementia, according to a multi-omics study published in Translational Psychiatry. Researchers from the Religious Orders Study (ROS) and the Rush Memory and Aging Project (MAP) found that while traditional pathology and genetic risk factors identify overall disease susceptibility, these … Read more

Brainstem Neurons Control Attention by Blocking Distractions

Researchers at Johns Hopkins University have identified a specific circuit of neurons in the brainstem that acts as a control center for selective spatial attention. By silencing these neurons in mice, scientists observed that the animals became hyper-distractable, failing to filter out competing visual information. This discovery, published in Nature Communications, suggests that the biological … Read more

Low Vitamin C Linked to Reduced Brain Connectivity

Low levels of vitamin C in the blood are linked to reduced gray matter volume and diminished connectivity in the brain’s default mode network, according to a study of 2,044 Japanese adults published in PLOS One. Researchers led by Haruka Nagaya of Hirosaki University found these associations remained significant even after accounting for age, physical … Read more

How Brain Remodeling Automates Complex Skills

The End of the Multitasking Myth: How Brain Rewiring is Redefining Human Potential For decades, the prevailing wisdom in cognitive science was simple: humans cannot truly multitask. We were told that the brain is a serial processor, rapidly switching focus between tasks, creating a “bottleneck” that limits our efficiency. However, groundbreaking new research is turning … Read more

How Histamine Boosts Memory, Decisions, and Learning

Beyond Dopamine: Why Histamine is the Next Frontier in Cognitive Enhancement For decades, the conversation around brain health and “smart drugs” has been dominated by two heavyweights: dopamine and serotonin. We talk about dopamine for motivation and serotonin for mood. But a groundbreaking shift is occurring in neurobiology, and it’s centering on a much older, … Read more

Neuroplex pipeline monitors nine neuronal populations in moving mice

The Shift Toward Multi-Circuit Neuroimaging For years, the field of neuroscience has operated under a significant constraint: the “two-color limit.” While researchers could observe brain activity in behaving animals using miniscopes, they were generally limited to distinguishing only two different types of brain cells at a time. This forced a slow, iterative process of testing … Read more
