Engaging in creative activities like dancing, music, art, or playing strategy video games is linked to a younger-looking brain and slower brain aging, with long-term practice providing stronger benefits. Even short-term creative training can improve brain aging markers, suggesting that regular creative engagement supports neural health and cognitive resilience.
NextBrain is a high-resolution, probabilistic human brain atlas built from multimodal histology and MRI data, enabling detailed segmentation and analysis of brain structures for research and clinical applications.
A study found that consuming a milkshake did not cause a significant dopamine release in the brain's reward region, challenging the idea that ultra-processed foods are highly addictive due to dopamine surges. The research showed individual variability in dopamine response, unrelated to body weight, and suggested that the reward response to such foods may be weaker than that of addictive drugs.
A study found that controlled fear experiences, like horror films, can temporarily alter brain patterns associated with depression, particularly reducing hyperconnectivity in brain networks linked to rumination, and may engage emotion regulation systems, suggesting potential therapeutic avenues.
Research analyzing 139 neuroimaging studies found that brain activity related to cognitive control peaks between ages 27 and 36, following an inverted U-shaped pattern across the lifespan, emphasizing the importance of brain health maintenance in midlife.
A large-scale study found that individuals with a higher genetic risk for major depression, measured by polygenic risk scores, tend to have smaller brain volumes and surface areas in specific regions such as the hippocampus, thalamus, and orbitofrontal cortex, with potential implications for early intervention and personalized treatment.
A study shows that high ventilation breathwork combined with music can induce altered states of consciousness similar to psychedelics, linked to specific changes in brain blood flow and emotional processing, with potential therapeutic benefits.
Research suggests that the thalamus plays a crucial role in regulating the timing of brain development and plasticity, extending beyond its traditional role as a relay station, with implications for understanding cognitive and emotional development in youth.
Researchers have developed DunedinPACNI, a tool that uses a single brain scan taken midlife to accurately assess biological aging and predict risks of diseases like dementia, potentially enabling earlier interventions to improve health outcomes.
Recent neuroimaging research reveals that individuals with psychopathy exhibit significant reductions in brain volume in regions responsible for emotional regulation, decision-making, and social behavior, providing a biological basis for their antisocial tendencies. The study highlights the complexity of psychopathy, with some traits showing less consistent neural correlations, and paves the way for targeted interventions based on neural differences.
A neuroimaging study suggests that long-term musical training helps older adults maintain youthful brain connectivity patterns, which may protect against age-related decline in speech understanding in noisy environments, supporting the idea that engaging in music can build cognitive reserve and promote brain health with age.
A study using neuroimaging has identified specific brain regions with reduced volume associated with antisocial traits in individuals with psychopathy, highlighting a neurobiological link between brain structure and antisocial behavior.
A new neuroimaging method called FREQ-NESS reveals that the brain dynamically reorganizes its networks in real time in response to rhythmic sounds, offering high-precision mapping of brain activity across frequencies with potential applications in neuroscience, perception, and mental health diagnostics.
New research suggests that electroconvulsive therapy (ECT) not only induces seizures but also triggers a brain 'reset' wave called cortical spreading depolarization (CSD), which may explain its rapid and widespread therapeutic effects. Using advanced neuroimaging, scientists aim to personalize ECT treatments by monitoring CSD as a biomarker, potentially improving outcomes for treatment-resistant mental illnesses.
A decade-long study tracking nearly 500 individuals from age 21 to 89 has released its comprehensive dataset, including brain scans and cognitive assessments, enabling global researchers to explore diverse pathways of healthy aging and cognitive decline.
