Dual-Targeting Drug Halts Tau Accumulation in Alzheimer’s

Scientists have developed a drug that targets both major aggregation-promoting sites of the Tau protein, a key player in Alzheimer's disease. This peptide inhibitor, RI-AG03, effectively prevents Tau buildup in lab studies and fruit flies, offering hope for new Alzheimer's treatments.

Psychedelics Reduce Anxiety Without Hallucinations

New research has pinpointed the specific brain region and neuron type responsible for reducing anxiety using the psychedelic drug DOI, without triggering hallucinations. The study revealed that DOI targets serotonin2A receptors on parvalbumin-positive neurons in the ventral hippocampus, decreasing anxiety behaviors in animal models.

Your Brain Divides the Day Into “Chapters” Based on Priorities

New research shows that the brain divides the day into "chapters" based on what a person focuses on. These mental boundaries aren't solely prompted by changes in surroundings but also by internal goals and priorities. In experiments using audio narratives, participants' brains organized events differently depending on whether they focused on specific details. This study suggests that how we experience and remember events is influenced by both context and what matters most to us at the time.

Neurology News Articles

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

Chronic Pain Patients Favor Cannabis Legalization

A study found that 71% of adults with chronic pain support federal legalization of medical cannabis, compared to 59% of physicians. The research highlights a gap in attitudes toward cannabis policies between patients and doctors, especially regarding insurance coverage for cannabis treatments.

Cannabis Pill Reduces Agitation in Alzheimer’s Patients by 30%

A new study reveals that dronabinol, a synthetic form of THC, can reduce agitation in Alzheimer’s patients by 30%. Unlike current medications, dronabinol showed fewer side effects, such as delirium or seizures, making it a safer alternative.

Personalized Immune Therapy Offers Hope for MS Patients

A new study explores the use of tolerogenic dendritic cells (tolDCs) to restore immune balance in multiple sclerosis (MS) patients without compromising their immune system. The research reveals that MS patients’ immune cells have a pro-inflammatory signature, even after being modified for therapy.

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 Model Predicts Complex Animal Movements

Scientists have developed a highly accurate model simulating animal movements, using the nematode worm C. elegans as a base. This model captures both predictable and random behaviors, with applications in medicine and robotics.

ChatGPT Matches Radiologists in Brain Tumor Diagnosis Accuracy

Researchers compared the diagnostic accuracy of GPT-4 based ChatGPT and radiologists using 150 brain tumor MRI reports. ChatGPT achieved 73% accuracy, slightly outperforming neuroradiologists (72%) and general radiologists (68%).

AI Reveals How Infants Learn to Interact with Environment

Researchers used artificial intelligence (AI) to study how infants transition from random movements to purposeful actions. By tracking infant movements in a baby-mobile experiment, AI models like 2D-CapsNet accurately classified these movements and identified significant changes in foot movements as infants learned to interact with their environment.

Psychology News Articles

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

Faulty Brain Processes Behind Hearing Voices in Schizophrenia

A new study reveals that auditory hallucinations in schizophrenia may be caused by two faulty brain processes: a failed suppression of self-generated sounds and an overactive response to internal noises. The research showed that patients with hallucinations had a "broken" corollary discharge and an enhanced response to unintended sounds, compared to those without hallucinations. These findings suggest that future treatments for auditory hallucinations could target these disrupted processes.

How Previous Food Choices Influence Future Decisions

Research shows that when rating food for appeal or calorie content, judgments are influenced by the food choices we’ve made just before. This effect, known as serial dependence, causes people to rate the next food similarly to the previous one, whether it’s more appealing or less.

Why People Are Better at Guessing the Past Than Predicting the Future

A new study shows that people are better at inferring past events than predicting future ones when watching scenes from TV dramas. The researchers found that participants were more accurate in guessing what had happened earlier in the story because characters tend to talk about their pasts more often than their futures.

Gut Microbiome and Aspirin May Reverse Hormonal Issues

Researchers found that mutations in the Sox3 gene cause hypopituitarism, a condition where the pituitary gland produces insufficient hormones, leading to growth issues and infertility. In a study on mice, they discovered that Sox3 mutations affect brain cells called NG2 glia, which are essential for hormone production.

Cadmium Exposure Linked to Memory Issues

A recent study explored the link between cadmium exposure and cognitive decline, finding that higher cadmium levels may be associated with thinking and memory problems in white people. The study followed 2,172 people over 10 years, with results showing no association overall but revealing a possible link when analyzing Black and white participants separately.

Study Supports Quantum Basis of Consciousness in the Brain

A new study suggests that consciousness may be rooted in quantum processes, as researchers found that a drug binding to microtubules delayed unconsciousness in rats under anesthesia. This discovery supports the idea that anesthesia acts on microtubules, potentially lending weight to the quantum theory of consciousness. The research challenges classical models of brain activity, suggesting that consciousness could be a collective quantum vibration within neurons. These findings could reshape our understanding of consciousness, with implications for anesthesia, brain disorders, and consciousness in non-human animals.

Manipulating Brain Waves During Sleep With Sound

Sound stimulation can manipulate brain waves during REM sleep, a stage crucial for memory and cognition. Using advanced technology, researchers were able to increase the frequency of brain oscillations that slow down in dementia patients, potentially improving memory functions. The non-invasive technique could pave the way for innovative treatments for dementia by targeting brain activity during sleep. This approach offers hope for enhancing memory and cognition with minimal disruption to patients' lives.

Anti-inflammatory Drug Boosts Motivation in Depression

A new study reveals that infliximab, an anti-inflammatory drug, can improve motivation in patients with depression and high inflammation. Researchers found that patients receiving infliximab showed greater effort in reward-based tasks, correlating with changes in brain activity in key motivation regions.
