Neuroscience News Home

Neuroscience News is an independent open access science magazine. Since 2001, we have featured neuroscience research news from labs, universities, hospitals and news departments around the world. Topics include brain research, AI, psychology, neuroscience, mental health and neurotech.

Science news articles cover neuroscience, neurology, psychology, AI, mental health, robotics, neurotechnology and cognitive sciences.

A new study reveals that microRNAs—tiny regulators of gene expression—play a crucial role in shaping Purkinje cells, rare brain neurons linked to movement and neurodevelopmental disorders. Using advanced genetic tools, researchers showed that disabling microRNAs during specific developmental windows impaired the cells’ growth and ability to form key connections.
A new study using intracranial recordings in humans reveals that the thalamus, particularly its higher-order regions, plays a central role in triggering conscious perception. By monitoring brain activity during a visual task, researchers found that the intralaminar and medial thalamic nuclei activated before the prefrontal cortex, suggesting the thalamus initiates conscious awareness.
A new study challenges the widely held belief that high-quality, nonjudgmental listening is essential for persuasion. While good listening improves how people feel about a conversation and reduces defensiveness, it doesn’t enhance the impact of persuasive messages.

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

A large study of over 72,000 pregnant women found that those infected with SARS-CoV-2 during pregnancy were less likely to develop Long COVID than non-pregnant peers. Using data from two national databases, researchers found consistent results: about 16% of pregnant women developed Long COVID symptoms versus 19% of matched non-pregnant women.
A new study shows that weight training not only boosts physical strength but also protects the brains of older adults with mild cognitive impairment. After six months of twice-weekly resistance training, participants showed memory improvements and protection against brain atrophy in regions linked to Alzheimer’s disease.
New research shows that reduced time in slow wave and REM sleep is associated with smaller brain volumes in regions vulnerable to Alzheimer’s disease. Using sleep studies and brain imaging data from 270 participants, researchers found that poor sleep architecture was linked to brain atrophy over time—particularly in the inferior parietal region, an area affected early in Alzheimer’s.

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

Researchers have developed a brain-computer interface that can synthesize natural-sounding speech from brain activity in near real time, restoring a voice to people with severe paralysis. The system decodes signals from the motor cortex and uses AI to transform them into audible speech with minimal delay—less than one second.
A new study finds that ChatGPT, while excellent at logic and math, exhibits many of the same cognitive biases as humans when making subjective decisions. In tests for common judgment errors, the AI showed overconfidence, risk aversion, and even the classic gambler’s fallacy, though it avoided other typical human mistakes like base-rate neglect.
Researchers have developed a new kind of artificial neuron—called infomorphic neurons—that can independently learn and self-organize with nearby neurons, mimicking the decentralized learning of biological brains. Inspired by pyramidal cells in the cerebral cortex, these neurons process local signals to adapt and specialize in tasks without external control.

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

In the first study of its kind, researchers found that psychedelic use can positively affect sexuality, romantic relationships, and gender expression. Surveying nearly 600 users of substances like psilocybin, LSD, and ketamine, the study revealed that many participants reported increased partner attraction, improved intimacy, and enhanced sexual experiences.

A new study highlights that olfactory testing could offer a simple, cost-effective way to detect early cognitive impairment from home. Researchers found that older adults with mild cognitive issues performed worse on odor identification and memory tasks than cognitively normal individuals.
A new study reveals that herpes simplex virus-1 (HSV-1), commonly known for causing cold sores, can travel through the nasal cavity directly to the brain, causing severe and lasting neurological symptoms. In animal experiments, nasal HSV-1 infection led to persistent neurological dysfunction, including anxiety and cognitive impairment.
A new study reveals that autism-like symptoms in mice emerge when two nerve proteins—MDGA2 and BDNF—fall out of balance. MDGA2 typically keeps BDNF/TrkB signaling in check, but when MDGA2 levels drop, heightened neuronal activity and social impairments occur.
Rejuvenating the brain's lymphatic vessels can enhance memory in aging mice by improving the removal of waste products from the brain. This research suggests that targeting the meningeal lymphatics—vessels outside the brain—could be a novel approach to treating age-related cognitive decline without directly crossing the blood-brain barrier.
