Inherited brain activity predicts childhood risk for anxiety, research finds
A new study focused on anxiety and brain activity pinpoints the brain regions that are relevant to developing childhood anxiety. The findings may lead to new strategies for early detection and treatment of at-risk children.

When memory-related region of brain is damaged, other areas compensate, study finds
Many neuroscientists believe the loss of the brain region known as the amygdala would result in the brain's inability to form new memories with emotional content. New research indicates this is not so, and suggests that when one brain region is damaged, other brain regions can compensate.

Brain Aging: Men and Women Do It Differently
Improved structural and functional brain imaging technologies provide assistance in understanding brain gender differences. A Japanese study of the effects of age and gender has been recently published in Human Brain Mapping. The study focussed on brain gray and white matter volumes in a variety of brain regions. Gray matter volumes declined with age in both genders. In the younger subjects,

Losing Sleep, Losing Brain?
Chronic and severely stressful situations, like those connected to depression and posttraumatic stress disorder, have been associated with smaller volumes in "stress sensitive" brain regions, such as the cingulate region of the cerebral cortex and the hippocampus, a brain region involved in memory formation...

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.

For older adults, participating in social service activities can improve brain functions
Volunteer service, such as tutoring children, can help older adults delay or reverse declining brain function, according to a new study. Using functional magnetic resonance imaging (fMRI), the researchers found that seniors participating in a youth mentoring program made gains in key brain regions that support cognitive abilities important to planning and organizing one's daily life.

Logic and language are not the same thing
It's difficult for us to imagine what our mental lives would be like without language. Some theorists have even gone so far as to argue that language and logical thought are one and the same thing. A new brain imaging study challenges this notion by showing that logical inferences based on simple "not", "or", "if", "then" terms activate a separate, though overlapping, network of brain regions com

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
