People with behavioral addictions show abnormal brain connectivity, with disrupted communication in networks responsible for attention, emotional regulation, and reward processing, potentially explaining difficulties in controlling addictive behaviors.
Elon Musk's Neuralink promises a vision-restoring cortical implant, but new research suggests vision from such devices will remain grainy due to the complexity of brain neurons. Accurate sight restoration requires understanding neural patterns, not just adding electrodes.
A new study reveals that racism accelerates biological aging in Black women by altering brain networks linked to stress and rumination, highlighting the profound impact of racial discrimination on mental and physical health at the cellular level.
Romantic couples exhibit higher brain synchronization during interactions compared to strangers, with stronger neural connections linked to greater honesty, according to new research.
A new neuroimaging study has found that people with alcohol use disorder show reduced brain activity when alcohol-related distractions are present.
Researchers found that blocking a protein called Activin A can prevent dyskinesia, a debilitating side effect of Parkinson's treatment, potentially allowing patients to stay on levodopa longer without developing uncontrollable movements.
Brain imaging research has found that highly creative individuals' brains are more connected during rest but become less locally focused during creative tasks.
Psychological stress disrupts communication between the brain and gut, reducing protective mucus production in the intestines. This weakens the immune system and makes the body more vulnerable to infections, but probiotics may help restore balance.
The COVID-19 virus mutates faster in the brain than in the lungs, potentially explaining neurological symptoms like brain fog. These mutations may help the virus adapt, raising concerns about the evolution of new variants.
Shorter sleep and late bedtimes in children, especially those from low-income families, are linked to smaller amygdala size and weaker brain connections, potentially affecting emotional regulation and increasing the risk of stress-related mental health problems.
Olympic-level athletes in closed-skill sports (like rowing) show different brain activity than non-athletes during memory and inhibition tasks, highlighting different neural strategies for cognitive tasks.
A study found that prolonged sunlight exposure, especially over two hours daily, may be linked to reduced brain volume and increased markers of brain aging, with more pronounced effects in men and individuals under 60 years old.
Scientists restored age-related decline in brain waste clearance in mice using an existing drug, prostaglandin F2 alpha. This approach may help prevent toxic protein buildup linked to Alzheimer’s and Parkinson’s, offering potential for future neurological disease treatments.
Researchers found that curiosity is triggered by uncertainty in the brain. Using brain imaging, they identified that when visual ambiguity increased, activity in specific brain regions, including the occipitotemporal cortex and ventromedial prefrontal cortex, was linked to heightened curiosity.
A study found that rats raised on a high-fat diet gained weight, developed metabolic issues, and showed enhanced emotional memory, linked to increased neurotransmitter activity in specific brain regions involved in memory and emotions.
