Grey Matter News and Research

RSS

Grey matter is a major component of the central nervous system, consisting of neuronal cell bodies, neuropil (dendrites and both unmyelinated axons and myelinated axons), glial cells (astroglia and oligodendrocytes) and capillaries.

Meditation associated with increased cortical thickness

Meditation is known to alter resting brain patterns, suggesting long lasting brain changes, but a new study by researchers from Yale, Harvard, Massachusetts General Hospital, and the Massachusetts Institute of Technology shows meditation also is associated with increased cortical thickness.

Scientists say there is less white matter in the frontal lobes of those who struggle with focusing

When it comes to focusing on a task amid distractions, some folks more than 60 years old are as mentally sharp as 22-year-olds. Others struggle. Researchers at the Beckman Institute for Advanced Science and Technology at the University of Illinois at Urbana-Champaign have shed some light on why that is.

Teens with missing part of a chromosome confirm genetic role in schizophrenia

A study in youth who are missing part of a chromosome is further implicating a suspect gene in schizophrenia.

Pathological liars found to have less gray matter

In a new study Dr. Adrian Raine and Yaling Yang of the University of Southern California, and colleagues found that individuals who habitually lied and cheated had less gray matter and more white matter in their prefrontal cortex than normal people.

New way to measure the impact of AIDS on the living brain

A new University of California - Los Angeles/University of Pittsburgh imaging study for the first time shows the selective pattern of destruction inflicted by AIDS on brain regions that control motor, language and sensory functions. High-resolution 3-D color scans created from magnetic resonance images (MRI) vividly illustrate the damage.

Brain abnormalities in people who habitually lie

While previous research has shown that there is heightened activity in the prefrontal cortex - the area of the brain that enables most people to feel remorse or learn moral behavior - when normal people lie, this is the first study to provide evidence of structural differences in that area among pathological liars.

Alcoholics who smoke appear to lose more brain mass than alcoholics who don't smoke

It is already well-known that the brains of long-term alcoholics atrophy and shrink, the study authors say, but the new findings are the first evidence that cigarette smoking might contribute to that atrophy, particularly in grey matter of the parietal and temporal lobes.

Causes, consequences and clinical implications of alcohol-related brain shrinkage

Previous studies have demonstrated that the brains of alcoholics are smaller, lighter and "shrunken" when compared to nonalcoholic brains.

"Anxiety Gene" linked to depression, makes the body out of tune

U.S. scientists in viewing the human body as a well-tuned orchestra, say that think they may have found a discordant note in the form of a gene which appears to increase the likelihood of some people developing anxiety and depression.

Suspect gene may increase susceptibility to anxiety and depression

People with the depression-linked gene variant showed less gray matter and weaker connections in the mood-regulating circuit. How well the circuit was connected accounted for nearly 30 percent of their anxious temperament

MRI study shows hormone leptin alters brains, may ease cravings of people with obesity gene

A magnetic resonance imaging (MRI) study finds that the protein hormone leptin promotes development of gray matter in the part of the brain that regulates cravings and the ability to monitor personal behavior.

Important new finding about the brain and its stem cells

A family's bravery and generosity in the face of their son's death three years ago has enabled researchers to make an important new finding about the brain and its stem cells.

New antipsychotic drug prevents brain loss in schizophrenia

A new brain imaging study of recently diagnosed schizophrenia patients has found, for the first time, that the loss of gray matter typically experienced by patients can be prevented by one of the new atypical antipsychotic drugs, olanzapine, but not by haloperidol, an older, conventional drug.

Different antipsychotic medications may have different effects on brain volume in patients with first episode of psychosis

After a first psychotic episode, patients who were treated with an atypical antipsychotic medication had less change in brain volume compared with patients treated with a conventional antipsychotic medication, according to an article in the April issue of Archives of General Psychiatry.

Docosahexaenoic acid may protect against the accumulation of a protein believed to be linked to Alzheimer's disease

Docosahexaenoic acid (DHA), an omega-3 fatty acid, may protect against the accumulation of a protein believed to be linked to Alzheimer's disease, according to the results of a new study published in the March 30, 2005 issue of The Journal of Neuroscience. The study used Martek DHA, which is produced from microalgae.
