The researchers found that gray matter
volume increased in the areas of the brain that control leg movement, which may reflect changes related to the brain learning how to move in microgravity, while in other areas of the brain, gray matter
volume decreased due to redistribution of the CSF.
Based on the research to date, "we know that fibromyalgia patients have altered pain processing, loss of brain gray matter
, changes in white matter tracts, changes in neurochemical function, and cognitive deficits," Dr.
Increased iron in deep gray matter
was correlated inversely and significantly with performance on several neuropsychological tests, including the Rey Complex Figure Test, the California Verbal Learning Test, and the Digit Span Backward test, Dr.
People in both groups showed a loss of gray matter
as they aged.
The findings further suggest that clues to the treatment of other diseases long believed to be focused in the brain's gray matter
- such as Alzheimer's disease, Huntington's disease and Parkinson's disease - may be informed by studies of diseases of the white matter, such as multiple sclerosis (MS).
In families with patients who have bipolar disorder, gray matter
deficits seen on MRI also correlated with increased genetic liability, but the extent of the gray matter
deficits was much less than in the schizophrenia families.
They find that about a month of treatment with the drug increases the volume of gray matter
in a person's brain.
Exercise your gray matter
this summer by checking out these scientific happenings.
They found that the most important areas of white and gray matter
don't always overlap.
In the important brain areas that varied in volume with stress, the white and gray matter
volumes were lower in tandem.
Previous research has concluded that heavy drinking is associated with depleted cortical gray matter
volume and diminished levels of N-acetylaspartate (a marker of neuronal viability) in the lower frontal white matter and gray matter
Preliminary data suggest that deceitful, violent men diagnosed with antisocial personality disorder have a reduced amount of gray matter
in the brain's prefrontal cortex.
It found that adolescents diagnosed with schizophrenia and other psychoses appear to show greater decreases in gray matter
volume and increases in cerebrospinal fluid in the frontal lobe compared to healthy adolescents without a diagnosis of psychosis.
