Obesity and higher body mass are linked to decreased cerebral blood flow. Lower cerebral blood flow is associated with an increased risk of Alzheimer's disease and a range of psychiatric disorders. Read More

Males with autism have atypically enhanced excitation in the medial prefrontal cortex (mPFC). This area of the brain is associated with social cognition and self-reflection. Autistic women showed a more intact mPFC response, which was associated with a better ability to camouflage social difficulties in real-world settings. Read More
Compared to typically developing children, those with disruptive behavioral disorders, characterized by antisocial behaviors and aggression, had less gray matter in the amygdala and hippocampus. Read More
High resolution imaging reveals the human cerebellum is 80% of the area of the cortex. The findings indicate this area of the brain likely grew larger as human behavior and cognition evolved. Read More
A new human brain atlas features 250 structurally distinct areas, each based on the analysis of ten brains. Over 2400 brain sections were digitalized and assembled in 3D to create the new map. Read More
Those with MS allocate neural resources less effectively when faced with increased cognitive task demands, and this likely results in the increased mental fatigue those with the neurodegenerative disorder experience. Read More
First responders at the World Trade Center have reduced cortical gray matter thickness, which was consistent with neurodegenerative conditions and evidence their brain age is, on average, ten years older than those of similar ages in the general population. Read More
Cortical thickness and regional brain connectivity pay an equally important role in linking brain and behavior. Read More
APOEe4, a gene associated with Alzheimer's disease risk, doesn't appear to directly affect memory performance or brain activity in older adults without cognitive impairment. However, the gene does seem to influence brain regions and systems that older at-risk adults activate to support successful memory recall. Read More
PET neuroimaging reveals super-agers and those whose cognitive skills are above the norm for an advanced age have an increased resistance to tau and amyloid proteins. Read More
Researchers have discovered a brain-based marker for new thoughts, reporting people experience more than 6,000 thoughts per day. The study reports a new method that can detect indirectly when one thought ends and another begins. Read More
Using artificial intelligence and neuroimaging, researchers have identified a link between mental imagery and vision. The brain uses similar visual areas for mental imagery and vision but uses low-level visual areas less precisely for mental imagery than vision. Read More
