Social Isolation Directly Speeds Up Cognitive Decline

Social isolation has a direct causal impact on how quickly cognitive function declines in later life, independent of whether someone feels lonely. By analyzing more than 137,000 cognitive tests from over 30,000 older adults, the study found that reduced social contact consistently predicted faster decline across every demographic group.

fMRI Signals Often Misread Neural Activity

fMRI signals don’t always match the brain’s true activity levels, overturning a core assumption used in tens of thousands of studies. In about 40% of cases, an increased fMRI signal appeared in regions where neural activity was actually reduced, while decreased signals sometimes showed up in areas with heightened activity.

Two Dopamine Neuron Subtypes Process Smell in Different Ways

Closely related dopamine-releasing neurons in the olfactory bulb behave in fundamentally different ways depending on their physical structure. One subtype releases neurotransmitters from dendrites instead of axons—an unusual mechanism that allows the cells to act locally and even self-inhibit.

Why Consciousness Evolved

New work explores why consciousness evolved and what observing birds can teach us about its biological purpose. The findings outline three distinct forms of consciousness—basic arousal, general alertness, and reflexive self-awareness—each providing unique adaptive advantages.

Exercise Supercharges Hormone Transport to the Brain

Physical exercise triggers extracellular vesicles (EVs)—tiny particles in the blood—to act as temporary transport shuttles for key hormone precursors. During vigorous exercise, levels of the hormone precursor POMC attaching to EVs increase fourfold, suggesting a newly uncovered mechanism for how stress, energy balance, and mood may shift after movement.

Neurology News Articles

Neurology news articles cover neurology, brain cancer, traumatic brain injuries, neurosurgery, neuroanatomy, brain research and neurological disorders.

Cancer Disrupts the Brain’s Internal Clock

Breast cancer can rapidly derail the brain’s day-night regulation of stress hormones, even before tumors are detectable. In mice, the disease flattens normal corticosterone rhythms by altering hypothalamic neuron activity, which may worsen outcomes and mimic symptoms often seen in cancer patients, such as insomnia and anxiety.

Tiny Gut Imposters Could Be Driving Multiple Sclerosis

New research reveals that when gut bacteria closely resemble the myelin sheath that protects nerve fibers, the immune system can become confused and attack both — accelerating multiple sclerosis. In mouse experiments, bacteria engineered to mimic myelin triggered faster disease progression by activating aggressive immune cells that infiltrated the nervous system.

Blood Transfusions May Accelerate Alzheimer’s Progression

New research shows that blood from older animals can speed up Alzheimer’s-related changes in the brain, while young blood may slow them down. In a long-term experiment, mice engineered to develop Alzheimer’s symptoms received weekly blood infusions from either young or old donors.

AI Turns Simple EEG Scans Into Accurate Dementia Detectors

New research shows that deep learning can use EEG signals to distinguish Alzheimer’s disease from frontotemporal dementia with high accuracy. By analyzing both the timing and frequency of brain activity, the model uncovered distinct patterns: broader disruption across multiple regions in Alzheimer’s and more localized frontal and temporal changes in frontotemporal dementia.

Nicotine Withdrawal Makes Smokers More Sensitive to Pain

A new study shows that abstinent smokers experience heightened pain sensitivity linked to altered activity in specific brain regions. Compared to nonsmokers, abstinent smokers required more postoperative pain relief—especially opioids—and their pain sensitivity increased the longer they remained nicotine-free.

AI News Articles

AI news articles cover science articles about artificial intelligence including ChatGPT, Bard, Dalle, neural networks, machine learning, LLMs, AGI and other AI related topics.

AI Brain Model Reveals How Fear Works in Real Life

Researchers have developed an AI-driven brain model that can track fear as it unfolds in real-world situations, offering a major shift from traditional lab-based approaches. Classic fear studies often rely on static images, but these do not reflect how the brain processes fear in dynamic contexts.

AI-Powered Bionic Hand Restores Natural, Intuitive Grasping Ability

A new study shows that integrating artificial intelligence with advanced proximity and pressure sensors allows a commercial bionic hand to grasp objects in a natural, intuitive way—reducing cognitive effort for amputees. By training an artificial neural network on grasping postures, each finger could independently “see” objects and automatically move into the correct position, improving grip security and precision.

Brain Uses AI-Like Computations for Language

The human brain processes spoken language in a step-by-step sequence that closely matches how large language models transform text. Using electrocorticography recordings from people listening to a podcast, researchers found that early brain responses aligned with early AI layers, while deeper layers corresponded to later neural activity in regions such as Broca’s area.

AI Is Changing the Way Humans Grieve, Remember, and Face Death

Generative artificial intelligence is quietly reshaping how humans process grief, remembrance, and mortality. Digital reconstructions of the deceased may offer comfort, but they also risk blurring the natural boundary between presence and absence.

AI Watches Pianists and Reconstructs Their Muscle Signals

Researchers developed an AI system that can reconstruct fine hand muscle activity using only standard video footage. Traditionally, this type of measurement required intrusive electrodes attached to the skin, but the new method eliminates that need entirely.

Psychology News Articles

Science research articles cover psychology, depression, mental health, schizophrenia, mental disorders, happiness, stress, PTSD, autism, psychiatry and therapy.

Second-Hand Gifts Are Becoming the New Status Symbol

New research shows that buying second-hand gifts is typically a thoughtful, intentional decision rather than an impulsive one. Consumers are motivated by fair prices, the thrill of finding rare items, and the desire to shop sustainably. Survey results from a major online marketplace reveal that intentions often translate directly into purchases—especially for items that are easy to evaluate, such as books.

Study Challenges Myths About Self-Centeredness

A large international study of more than 45,000 people shows that narcissism is a universal personality trait—not one concentrated in any single country. Although nations differed somewhat, the five highest-scoring countries were Germany, Iraq, China, Nepal, and South Korea, with the United States ranking 16th.

Stress Levels Predict Cannabis Use

New research shows that rats with naturally higher baseline stress hormone levels are significantly more likely to self-administer cannabis vapor. Over several weeks, rats were allowed to nose-poke for cannabis, and those with elevated corticosterone displayed the strongest drug-seeking behavior.

Positive Imagining Changes the Brain in Seconds

Vividly imagining a positive interaction with someone can increase how much you like them — and even alter how your brain stores information about that person. During imagined encounters, participants developed stronger preferences, and brain scans revealed activity patterns similar to those seen when people learn from real rewarding experiences.

Reading Habits Predict Hidden Biases Toward Autism

A new study shows that the newspapers people read are strong predictors of their automatic, unconscious biases toward autism—even after accounting for age, education, political views, and personal experience. Readers of right-leaning tabloid outlets showed more negative automatic biases, reflecting the more stereotyped and less frequent coverage of autism in these publications.

Many Autism Cases May Be Preventable

A new study proposes that autism arises when genetic vulnerability, an early environmental trigger, and prolonged activation of the cellular stress response align during critical developmental windows. This “three-hit” metabolic model reframes autism as a disorder of disrupted cellular communication and energy metabolism rather than an inevitable genetic outcome.

Supplement Mix Reverses Autism Traits

Researchers have made a major advance, discovering that a low-dose mixture of zinc, serine, and branch-chain amino acids (BCAAs) can successfully alleviate behavioral symptoms in three different mouse models of autism. This breakthrough lies in the synergy of the three common nutrients, which work together to restore normal neural communication and reduce hyperactivity in the brain's emotional center.

The Way You Drive Might Signal Mild Cognitive Impairment

Researchers found that long-term driving behavior can reveal early signs of cognitive decline years before clinical diagnosis. Older adults who later developed impairment showed gradual reductions in trip frequency, night driving, and route variety compared to cognitively healthy peers.

Boosting Sleep Ripples Helps Preserve Memories Normally Forgotten

A new study shows that precisely manipulating brain activity during sleep can help mice retain memories that would normally fade, offering a potential pathway for treating memory loss conditions. Researchers identified a specific sleep-related pattern—large sharp-wave ripples—that signals when new experiences are being transferred from the hippocampus to the neocortex for long-term storage. By boosting these ripples at just the right moment using optogenetics, scientists enabled mice to remember brief encounters they would typically forget.

Supplement Shows Promise in Blocking Amyloid in Alzheimer’s

A new study shows that oral arginine, a naturally occurring amino acid, can significantly suppress amyloid-β aggregation in Alzheimer’s disease models. Researchers found that arginine not only prevented Aβ42 from clumping but also reduced plaques and inflammation in mouse and fruit fly models carrying Alzheimer’s-related mutations.
