A weak heart also damages the brain

Heart insufficiency has a negative impact on gray matter in the brain. Weak heart function was linked to decreased gray matter in areas of the brain associated with memory and learning, including the hippocampus and parietal medial cortex. This may increase the risk of Alzheimer's disease.

Exercise is good for your brain’s gray matter

Cardiorespiratory exercise improves gray matter volume in areas of the brain associated with age-related cognitive decline. The findings add weight to the previous studies which link physical activity to neuroprotection against age-related cognitive decline.

Developmental changes in the brain may influence how often adolescents get drunk

Teens with a particular pattern of brain development have an increased frequency of drunkenness, a new study reports. Decreased gray matter density in the frontal and temporal brain regions was associated with an increased risk of teenage over-drinking.

Cellular aging is linked to structural changes in the brain

Telomere lengthening resulted in structural changes in the brain, including cortical thickening. By contrast, telomere shortening is associated with gray matter reduction, specifically in the precuneus.

How people with psychopathic traits control their ‘dark impulses’

Neuroimaging reveals 'successful' psychopaths (those who can control their antisocial tendencies) have greater levels of gray matter density between the left and right ventromedial prefrontal cortex. This area of the brain is implicated in self-regulatory processes, including reactive emotions.

Brain imaging may help identify teens at risk of increasing alcohol use

Neuroimaging study reveals teens with more gray matter in the caudate nucleus and left cerebellum were at increased risk of problem alcohol use over time. The findings reinforce the idea that brain structure differences may contribute to both psychiatric and substance use disorders.

Biological toll on brain function of Holocaust survivors revealed

Neuroimaging reveals Holocaust survivors have decreased gray matter in brain structures associated with emotional processing, memory, and social cognition. Early results show similar neuroanatomical changes in the children of survivors, suggesting an epigenetic link.

Research Into Brain’s Reaction to Motion Earns Significant Attention

Neuroimaging helps researchers observe what happens in the brain as a person is rotated. The study, which gives insight into how the brain moves after the head stops moving, also provides critical information for advancing studies of TBI.

Autism gene linked to brain and behavior deficits in mice

A deficiency of the SHANK3 gene, a gene associated with ASD, results in structural and functional deficits in the prefrontal cortex. The functional and structural alterations in the PFC were linked to an impairment in social interaction in male mice.
