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.

Researchers uncover how specific brain cells and circuits become vulnerable in Alzheimer's disease and identify factors that may promote resilience to cognitive decline. Analyzing gene expression in over 1.3 million cells across multiple brain regions, the study highlights the role of Reelin in neuron protection and choline metabolism in astrocytes for cognitive resilience. These findings pave the way for potential therapeutic targets to sustain cognition and memory amid Alzheimer’s pathology.
Visualizing breathing patterns can improve interoceptive awareness and mental well-being. Researchers used a spherical object on screens and spatial audio to mirror users’ breaths, significantly enhancing their bodily awareness and flow state. This immersive sensory experience highlights the connection between external stimuli and internal bodily signals, potentially aiding mental health.
A new study reveals that chronic and new anxiety are linked to a higher risk of dementia, while resolved anxiety shows no such association. Following 2,132 Australian individuals for 10 years, researchers found that chronic and new anxiety increased dementia risk by 2.8 and 3.2 times, respectively. Those whose anxiety began before age 70 faced even greater risks. The findings suggest that addressing anxiety could help prevent dementia.

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

Exercising our brains with daily habits like naps and memory workouts, instead of relying on smartphones, can reduce the risk of age-related dementia. A new study highlights the superiority of human intelligence over AI. The study emphasizes nurturing our brain's potential for healthy aging. It also offers practical tips for boosting brain power and maintaining real intelligence.
Researchers developed a new method, burst sine wave electroporation (B-SWE), to treat glioblastoma, a fast-growing brain tumor. B-SWE disrupts the blood-brain barrier more effectively than traditional methods, allowing cancer drugs better access to the brain.
Researchers established new criteria for Limbic-predominant Amnestic Neurodegenerative Syndrome (LANS), a memory-loss condition often mistaken for Alzheimer's disease. Unlike Alzheimer’s, LANS progresses more slowly and has a better prognosis. The criteria help doctors diagnose LANS in living patients using brain scans and biomarkers. This advancement aids in better management and tailored treatments for memory loss.

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

A new study examines the possibility of consciousness in artificial systems, focusing on ruling out scenarios where AI appears conscious without actually being so. Using the free energy principle, the study highlights that while some information processes of living organisms can be simulated by computers, the causal structure differences between brains and computers may be crucial for consciousness. This approach aims to prevent the inadvertent creation of artificial consciousness and mitigate deception by seemingly conscious AI.
Researchers used machine learning to identify three subtypes of Parkinson’s disease based on progression speed. These subtypes, marked by distinct genetic drivers, could enhance diagnosis and treatment strategies.
A new study reveals that over 60% of participants prefer AI over humans for redistributive decisions, despite finding AI decisions less satisfying and fair. Researchers conducted an online experiment with over 200 participants from the UK and Germany.

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

Individuals with the 22q11.2DS genetic deletion show unique patterns of brain activity and structure, which could predict their risk of psychosis. By studying brain "coupling" from childhood to adulthood, scientists discovered discrepancies in brain regions linked to schizophrenia.

A new study reveals the role of the molecule KIBRA in forming long-term memories. Researchers found that KIBRA acts as a “glue,” binding with the enzyme PKMzeta to strengthen and stabilize synapses, crucial for memory retention. This discovery could lead to new treatments for memory-related conditions. The findings confirm a long-standing hypothesis about memory storage mechanisms.
Mindfulness training can lead to altered states of consciousness, such as disembodiment and unity. Researchers found that participants were twice as likely to experience these states compared to a control group. While these experiences can be positive, they may also be startling or unpleasant. Mindfulness teachers and students should discuss these potential side effects.
A new study uncovers the different patterns and reasons behind procrastination using a mathematical framework. It shows that procrastination is influenced by factors like immediate rewards and uncertainty about future outcomes. These insights can help develop personalized strategies to combat procrastination and improve productivity. The research also highlights the importance of understanding individual procrastination behaviors.
Astrocytes, star-shaped glial cells in the brain, play a crucial role in learning and memory by regulating synaptic plasticity. Researchers developed a biophysical model showing how astrocytes interact with nerve cells to facilitate rapid adaptation to new information.
