Two brain areas fail to connect when children with attention deficit hyperactivity disorder attempt a task that measures attention, according to researchers.
The Brain Maintains Language Skills In Spite Of Alcohol Damage By Drawing From Other Regions Researchers know that alcoholism can damage the brain's frontal lobes and cerebellum, regions involved in language processing. Nonetheless, alcoholics' language skills appear to be relatively spared from alcohol's damaging effects. New findings suggest the brain maintains language skills by drawing upon other systems that would normally be used to perform other tasks simultaneously.
Excessive Drinking Can Damage Brain Regions Used For Processing Facial Emotions Heavy, constant drinking damages the brain in many different ways, including difficulties in perception of emotional expressions. Brain-imaging findings show that abstinent alcoholics have decreased activation in the amygdala and hippocampus regions of the brain when viewing faces with emotional expressions. Misreading facial cues can escalate conflict and difficulties, impaired social interactio
Precuneus Region Of Human And Monkey Brain Is Divided Into Four Distinct Regions New research provides a comprehensive comparative functional anatomy study in human and monkey brains which reveals highly similar brain networks preserved across evolution. Scientists examined patterns of connectivity to show that the precuneus, long thought to be a single structure, is actually divided into four distinct functional regions.
Words, Gestures Are Translated By Same Brain Regions Researchers have shown that the brain regions that have long been recognized as a center in which spoken or written words are decoded are also important in interpreting wordless gestures. The findings suggest that these brain regions may play a much broader role in the interpretation of symbols than researchers have thought and, for this reason, could be the evolutionary starting point from which
Neurons developed from stem cells successfully wired with other brain regions in animals Transplanted neurons grown from embryonic stem cells can fully integrate into the brains of young animals, according to new research. Healthy brains have stable and precise connections between cells that are necessary for normal behavior. This new finding is the first to show that stem cells can be directed not only to become specific brain cells, but to link correctly.
