Aerobic exercise may reduce the risk of dementia
Any exercise that gets the heart pumping may reduce the risk of dementia and slow the condition's progression once it starts, reported a Mayo Clinic study published this month in Mayo Clinic...
View ArticleAutism may involve disordered white matter in the brain
It's still unclear what's different in the brains of people with autism spectrum disorders (ASDs), but evidence from genetic and cell studies points to abnormalities in how brain cells (neurons)...
View ArticleBrain wiring a no-brainer? Scans reveal astonishingly simple 3D grid structure
The brain appears to be wired more like the checkerboard streets of New York City than the curvy lanes of Columbia, Md., suggests a new brain imaging study. The most detailed images, to date, reveal a...
View ArticleResearchers have identified a gene with a key role in neuronal survival
Spanish researchers at the Institute of Neurosciences at Universitat Autonoma de Barcelona (INc-UAB) identified the fundamental role played by the Nurr1 gene in neuron survival associated with synaptic...
View ArticleGifts of the MAGI in schizophrenia and bipolar disorder
These findings are not about the classic story of gift-giving, although the MAGI genes (officially named membrane associated guanylate kinase, WW and PDZ domain containing proteins) do influence brain...

(Medical Xpress)—A sudden and mysterious burst of activity originating in the retina of a developing fetus spurs brain connections that are essential to development of finely-tuned sight, Yale...
View ArticleDecreased gene activity is likely involved in childhood risk for anxiety and...
Decreased activity of a group of genes may explain why in young children the "fear center" of the anxious brain can't learn to distinguish real threats from the imaginary, according to a new University...
View ArticleHeavy prenatal alcohol consumption linked to childhood brain development...
(Medical Xpress)—Heavy drinking during pregnancy disrupts proper brain development in children and adolescents years after they were exposed to alcohol in the womb, according to a study supported by...
View ArticleEarly stress may sensitize girls' brains for later anxiety
High levels of family stress in infancy are linked to differences in everyday brain function and anxiety in teenage girls, according to new results of a long-running population study by University of...
View ArticleMind-controlled hand offers hope for the paralysed
Pentagon-backed scientists on Monday announced they had created a robot hand that was the most advanced brain-controlled prosthetic limb ever made.
View ArticleBrains of fetuses 'build a bridge' between regions, images show
(HealthDay)—Using real-time images of brain connections developing in late-stage fetuses, scientists say they've been able for the first time to compare the order and strength of these connections.
View ArticleAntidepressants alone are not enough
We should reconsider how we use antidepressants more effectively. The latest studies have shown that antidepressants restore the capacity of certain areas of the brain to repair abnormal neural...
View Article'Network' analysis of the brain may explain features of autism
A look at how the brain processes information finds a distinct pattern in children with autism spectrum disorders. Using EEGs to track the brain's electrical cross-talk, researchers from Boston...
View ArticleAlzheimer's risk gene discovered using imaging method that screens brain's...
(Medical Xpress)—Scientists at UCLA have discovered a new genetic risk factor for Alzheimer's disease by screening people's DNA and then using an advanced type of scan to visualize their brains'...
View ArticleDo you obsess over your appearance? Your brain might be wired abnormally
Body dysmorphic disorder is a disabling but often misunderstood psychiatric condition in which people perceive themselves to be disfigured and ugly, even though they look normal to others. New research...
View ArticleConnections in the brains of young children strengthen during sleep, study finds
While young children sleep, connections between the left and the right hemispheres of their brain strengthen, which may help brain functions mature, according to a new study by the University of...
View ArticleNew insights could result in changes to the therapeutic strategy to combat...
A typical characteristic of the brain of an Alzheimer sufferer is the presence of insoluble Tau protein aggregates. Scientists at VIB, KU Leuven and Janssen Pharmaceutica have demonstrated that the...
View ArticleNew imaging technique pinpoints changes in brain connectivity following mTBI
A new imaging technique can identify the specific changes in neural communication that can disrupt functional connectivity across the brain as a result of mild traumatic brain injury (mTBI). This...
View ArticleMRI studies point to brain connectivity changes in autism spectrum disorders
Studies using magnetic resonance imaging (MRI) techniques are beginning to reveal differences in brain connectivity—the ways that different parts of the brain are connected to each other and work...
View ArticleWilliam James revisited: Ongoing brain activity and connectivity influence...
The brain is an exceedingly complex and active organ in which most neural activity is not directly evoked by, and thereby linked to, specific external events. Moreover, intrinsic activity occurring in...
