Finding Upends Theory about the Cerebellum’s Role in Reading and Dyslexia
New findings dispute the popular cerebellar deficit hypothesis of dyslexia. Researchers report the cerebellum is not engaged during reading in typical readers and does not differ in children with dyslexia.... Read More...
Brain scans may provide clues to suicide risk
Neuroimaging can be used to assess a person's risk of suicidal behavior. Those with mood disorders, a history of suicidal thoughts, and those with a history of suicide attempts have less connectivity in the cognitive control network. They also have reduced connectivity between the cognitive control network and the default mode network.... Read More...
Drops in income may not only hurt the wallet, they may harm the brain
Experiencing an income drop of 25% or more impacts brain health and cognitive ability during middle age.... Read More...
What the brains of people with excellent general knowledge look like
An individual's level of general knowledge is associated with structural brain network connectivity. Fluid intelligence is best predicted by cortex volume in males, and by functional network connectivity in females. ... Read More...
What stress does to the brain
A new study sheds light on how the brain changes as a result of chronic stress. Selective noradrenaline release rewires connectivity patterns between different brain regions. Activity in the amygdala and networks that process sensory stimuli increased. ... Read More...
Structure of brain networks is not fixed
Brain networks are spatially and functionally fluid, and not static, as previously believed.... Read More...
Pigs help scientists understand human brain
Using resting state fMRI, researchers discover pig brains may be better models for studying human neurological conditions than previously thought.... Read More...
Brain Connections That Disadvantage Night Owls Revealed
A new MRI study reveals those who get to sleep and wake up late have lower resting brain connectivity in regions associated with the maintenance of consciousness. Researchers report the reduced brain connectivity is linked to poorer attention, slower reactions and increased daytime sleepiness.... Read More...
Different Brain Areas Linked to Smoking and Drinking Behaviors
A new study reveals researchers have identified areas of the brain which are different in those who regularly smoke and drink alcohol. Researchers discovered the medial orbitofrontal cortex, an area of the brain implicated in reward, has higher functional connectivity in drinkers. In those who smoke, the lateral orbiotfrontal cortex, an area of the brain linked to impulsive behavior, has lower functional connectivity. The study suggests nicotine may increase overall brain connectivity, which may lead to increased smoking behaviors. ... Read More...
Autism Behaviors Show Unique Brain Network Fingerprints in Infants
A new study reveals unique functional brain networks associated with characteristic behaviors of ASD in infants at risk of developing autism.... Read More...
Unique Patterns of Neural Communications Discovered in Brains of Autistic Children
A new study reveals unique connections within brain networks in children on the autism spectrum. Researchers say, in ASD, the amygdala shows marked differences in connection with the occipital cortex than in typically developing children.... Read More...
