Link Between Childhood Adversity and Muscle Dysmorphia in Youth

A new study reveals a significant association between adverse childhood experiences (ACEs) and symptoms of muscle dysmorphia in adolescents and young adults. The research highlights how ACEs, such as domestic violence and emotional abuse, can lead to the pathological pursuit of muscularity as a coping mechanism.

How Imagination Fuels Empathy and Prosocial Behavior

A new study highlights the significant role of imagination in evoking empathy and driving prosocial behavior. While empathy is multifaceted, this research focuses on two aspects: personal distress and compassionate concern. The study reveals that vividly imagining someone else's problems increases personal distress, motivating individuals to offer help.

Dopamine’s Role in Learning from Rewards and Penalties

Dopamine, a neurotransmitter, plays a vital role in encoding both reward and punishment prediction errors in the human brain. This study suggests that dopamine is essential for learning from both positive and negative experiences, enabling the brain to adapt behavior based on outcomes.

Neurology News Articles

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

High ‘Good Cholesterol’ Linked to Dementia Risk

A new study found that abnormally high levels of HDL-C (high-density lipoprotein cholesterol), often referred to as 'good cholesterol', may increase the risk of dementia in older adults. This large-scale study, part of the ASPREE project, observed over 18,668 participants, noting that those with very high HDL-C levels had a 27% higher risk of dementia.

Persistent Brain Repair Signals in Ex-NFL Players

A new study on former NFL athletes reveals prolonged high levels of the repair protein TSPO, indicating long-term brain inflammation post-injury. This protein, usually elevated after a traumatic brain injury (TBI) as part of the immune response, was found at high levels years after athletes ended their sports careers.

Innovative Fiber to Tackle Alzheimer’s Developed

A collaborative team is developing a neural fiber to combat Alzheimer’s disease. This high-priority NIH-funded project aims to create a minimally invasive fiber, capable of electrical stimulation and drug delivery, to study and potentially reverse memory loss.

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.

Taste-Driven AI Algorithms Enhance Wine Selections

Wine apps like Vivino and Hello Vino are utilizing AI algorithms to help wine enthusiasts select the perfect bottle. Researchers have taken it a step further by incorporating people's flavor impressions into the algorithms.

AI-Enhanced Imaging: Probing Brain’s Visual Processing

Researchers used AI to select and generate images for studying brain's visual processing. Functional MRI (fMRI) recorded heightened brain activity in response to these images, surpassing control images.

AI Reveals Brain Differences in ADHD

Researchers utilizing artificial intelligence (AI) to analyze brain MRI scans have identified significant differences in white matter tracts of adolescents with ADHD. The study, involving over 1,700 participants from the multi-institutional Adolescent Brain Cognitive Development Study, used diffusion-weighted imaging (DWI) and a deep-learning AI model to detect these variations.

Psychology News Articles

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

Peptide PACAP’s Key Role in Alcohol Addiction

Alcohol, the world's most common addictive substance, leads to $249 billion in annual costs and 88,000 deaths in the U.S. Alcohol use disorder affects millions but is under-treated. Researchers discovered a key player in alcohol addiction: pituitary adenylate cyclase activating polypeptide (PACAP).

RNA’s Pivotal Role in Fear Memory and PTSD Treatment

Researchers have revealed a groundbreaking role of RNA in fear-related learning and memory. Their study shows how noncoding RNA Gas5 influences neuronal excitability, impacting learning and memory processes.

Brain Brew: How Daily Coffee Habits May Affect Brain Plasticity and Learning

Researchers explore how chronic caffeine consumption potentially impacts brain plasticity and the effectiveness of repetitive transcranial magnetic stimulation (rTMS). The research indicates that regular caffeine users might experience diminished long-term potentiation (LTP), a crucial process for learning and memory.

How Anesthesia Blocks Consciousness

A new study reveals insights into how general anesthesia affects consciousness and sensory perception. Using animal models, researchers found that while propofol anesthesia allows sensory information to reach the brain, it disrupts the spread of signals across the cortex.

Color Concepts: How Bilingualism Influences Color Perception

Researchers discovered that the way we perceive and describe colors is influenced by the languages we speak. In a study with the Tsimane’ society from the Bolivian Amazon, bilingual individuals who learned Spanish as a second language began distinguishing colors differently than monolingual Tsimane’ speakers.

Brain Mapping Unveils Jhana Meditation Effects

A new study utilizing ultra-high field 7T MRI technology has mapped the brain's activity during jhana meditation, revealing distinct regional activations that correlate with advanced meditative states.

Genetic Links in Cannabis Use Disorder

Researchers analyzed over 1 million genomes, revealing insights into cannabis use disorder and its ties to psychiatric issues, other substance abuses, and lung cancer risks. The study, part of the Million Veteran Program, identified genetic variants linked to cannabis use disorder and its associated health and behavioral problems.
