AI Finds Shared Neural Patterns Across Minds

Researchers have developed a geometric deep learning approach to uncover shared brain activity patterns across individuals. The method, called MARBLE, learns dynamic motifs from neural recordings and identifies common strategies used by different brains to solve the same task.

Early Life Stress Rewires Brain Circuits Linked to Social Motivation

New research shows that early life stress disrupts dopamine signaling, altering social motivation and behavior. Scientists found that mice raised in stressful conditions were less likely to engage in social interactions compared to those with enriched experiences.

How the Body’s Clock Influences Eating and Weight Gain in Teens

A new study reveals that the body’s internal clock plays a key role in eating behavior, influencing when and how much adolescents eat. Researchers found that teens with overweight or obesity consumed significantly more calories later in the day compared to those with a healthy weight. By isolating circadian influences from environmental and behavioral factors, they confirmed that food intake peaks in the late afternoon and evening regardless of sleep duration or external time cues.

Neurology News Articles

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

Brain Bleeds Double Dementia Risk

Researchers have found that intracranial hemorrhages, or "brain bleeds," double the risk of developing dementia later in life. While ischemic strokes caused by blood clots have long been linked to cognitive decline, this study shows that hemorrhages also significantly increase dementia risk. Using Medicare data from nearly 15,000 patients, scientists observed a two-fold increase in dementia diagnosis within about 5.6 years after a brain bleed.

How CBD Modulates THC’s Impact on the Brain

Researchers have identified how CBD interacts with cannabinoid receptors to mitigate the negative effects of THC, the psychoactive component of cannabis. Unlike THC, which fully activates the receptor and causes side effects like memory loss and addiction, CBD acts as a modulator, fine-tuning receptor activity.

Imaging Reveals Gut-Brain Connection in Alzheimer’s Disease

Scientists have used advanced X-ray phase-contrast tomography (XPCT) to uncover how gut health may influence Alzheimer’s disease. The study found structural changes in the gut of Alzheimer’s-affected mice, revealing abnormalities in intestinal cells, neurons, and mucus secretion.

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-Enhanced Chip Unravels Brain’s Neural Networks

Researchers have mapped over 70,000 synaptic connections in rat neurons using a silicon chip with 4,096 microhole electrodes, significantly advancing neuronal recording technology. Unlike traditional electron microscopy, which only visualizes synapses, this method also measures connection strength, providing deeper insight into brain network function. The chip mimics patch-clamp electrodes but at a massive scale, enabling highly sensitive intracellular recordings from thousands of neurons simultaneously.

AI Reveals How Brain Cells Evolved Over 320 Million Years

A new study reveals how AI-driven deep learning models can decode the genetic regulatory switches that define brain cell types across species. By analyzing human, mouse, and chicken brains, researchers found that some brain cell types remain highly conserved over 320 million years, while others have evolved uniquely.

AI vs. Human Therapists: Study Finds ChatGPT Responses Rated Higher

A new study suggests that ChatGPT’s responses in psychotherapy scenarios are often rated higher than those written by human therapists. Researchers found that participants struggled to distinguish between AI-generated and therapist-written responses in couple’s therapy vignettes.

Psychology News Articles

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

Depression Speeds Up Physical Illness

Adults with a history of depression develop long-term physical conditions about 30% faster than those without, according to a large study. Researchers analyzed data from over 172,000 participants and found that those with depression accrued an average of 0.2 additional conditions per year, compared to 0.16 in those without.

Prenatal Stress Hormones Alter Brain Development

Environmental factors like stress and medication exposure during pregnancy can shape brain development, but the mechanisms remain unclear. Researchers used brain organoids to study the effects of synthetic glucocorticoids, commonly given to prevent complications in premature births.

How Ketamine Binds to Brain Receptors to Alter Mood

New research sheds light on how ketamine affects the brain by targeting a specific NMDA receptor subtype, GluN1-2B-2D. Scientists used electron cryo-microscopy to capture how ketamine binds to this receptor, revealing multiple attachment sites that influence brain activity.

Gut Microbiome Regulates Brain Signals Through the Vagus Nerve

New research provides direct evidence that the gut microbiome communicates with the brain through the vagus nerve. Using germ-free mice, scientists observed significantly reduced vagal nerve activity, which returned to normal after introducing gut bacteria.

Oral Microbiome May Influence Cognitive Decline and Brain Health

The microbial ecosystems in our mouths may impact cognitive function as we age, with pathogenic bacteria linked to cognitive decline. Researchers found that beneficial bacteria, such as Neisseria, are associated with improved memory and attention, while harmful bacteria like Porphyromonas correlate with mild cognitive impairment.

Maternal X Chromosome Accelerates Brain Aging

New research shows that female mice expressing only a maternal X chromosome experience faster brain aging and cognitive decline compared to those expressing both maternal and paternal X chromosomes. The maternal X accelerates aging in the hippocampus, a key region for memory and learning, and silences certain genes essential for brain health.

REM Sleep Delays May Indicate Early Alzheimer’s

Delayed rapid eye movement (REM) sleep may be an early indicator of Alzheimer’s disease. Researchers found that participants with delayed REM sleep had higher levels of toxic proteins associated with Alzheimer’s and reduced levels of brain-derived neurotrophic factor (BDNF), which supports memory.
