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.

Concussed athlete's brain may not fully recover even one year after return to play

How long does it take an athlete to recover from a concussion? New research has found an athlete's brain may still not be fully recovered one year after being allowed to return to play.

Cellular aging associated with structural changes in the brain

Telomeres are protective caps at the ends of chromosomes that become shorter with each cell division. If they become so short that the genes they protect could be damaged, the cell stops dividing and renewing.

Excess grey matter in the brain can predict escalating drinking behavior in teens

Teenagers with large amounts of grey matter in the brain at age 14 are more likely to increase their alcohol use over the next five years, according to a whole brain imaging study reported today in eLife.

Novel imaging molecule reveals brain changes linked to progressive MS

Secondary progressive multiple sclerosis is a relentless disease. Over time, patients experience worsening physical, mental and mood-related symptoms.

Researcher develops new computational statistical methodologies to deal with diffusion-MRI data

In her doctoral thesis at University of Jyväskylä, M.Sc. Jia Liu has developed and implemented a series of new computational statistical methodologies to deal with diffusion-MRI data.

Obesity linked to a reduction in gray matter

A new study suggests that obesity may be associated with changes in brain structure, including reduced brain volumes in certain areas.

Research shows how prenatal anesthesia in rats affects neuronal migration

While there has long been discussion whether exposure to anesthesia affects brain development, new Rush University Medical Center research published in the journal Cerebral Cortex describes how prenatal anesthesia in rats seems to disrupt the "precisely choreographed" and timed migration of neurons to the area of the developing brain where thinking, memory and language occur.

Scientists grow most sophisticated brain organoid to date

Researchers at Cambridge Biomedical Campus have grown the most sophisticated brain organoid to date, providing new opportunities for scientists to understand human brain development and neurological disorders.

Smoking, high blood pressure, obesity and diabetes associated with less healthy brains

Factors that influence the health of our blood vessels, such as smoking, high blood and pulse pressures, obesity and diabetes, are linked to less healthy brains, according to research published in the European Heart Journal today (Monday).

Abnormal timing found in the brains of people with autistic symptoms

The neural 'time windows' in certain small brain areas contribute to the complex cognitive symptoms of autism, new research suggests.

Researcher studies how sickle cell disease affects blood flow and oxygen delivery

Sickle Cell Disease is rare but devastating. Due to a genetic mutation affecting hemoglobin, the component of the red blood cell that carries oxygen, a reduced amount of oxygen is supplied to vital tissues and organs.

Study explains why women are more prone to Alzheimer’s disease

A study of 300 elderly individuals who underwent PET scans has revealed that women are more likely to develop the tau and beta-amyloid aggregates in the brain.

Sleep apnea patients struggle to remember details of life memories, study shows

People with sleep apnea struggle to remember details of memories from their own lives, potentially making them vulnerable to depression, new research has shown.

Study links concussions to development of epilepsy

Researchers at the Fralin Biomedical Research Institute at VTC have identified a cellular response in mice to mild traumatic brain injuries that may lead to seizures.

Low-level cannabis use can change the adolescent brain

Teenagers who report using recreational marijuana just once or twice display increased volume of numerous brain regions, according to a study of 14-year-olds from Ireland, England, France, and Germany.

Excess belly fat may lead to a reduction in gray matter

A new study has found that excess abdominal fat is associated with a lower volume of gray matter in the brain, resulting in a smaller brain size.

Intellectually active lifestyle confers protection against neurodegeneration in Huntington's patients

Researchers from the Cognition and Brain Plasticity research group of the Bellvitge Biomedical Research Institute and the University of Barcelona, in collaboration with several hospitals, have discovered that an intellectually active lifestyle confers protection against neurodegeneration in people with Huntington's disease, delaying the onset of symptoms and loss of grey matter in the brain.

Researchers identify potential diagnostic tool for Alzheimer’s disease

Researchers at Johns Hopkins Medicine have identified in live human brains new radioactive “tracer” molecules that bind to and “light up” tau tangles, a protein associated with a number of neurodegenerative diseases including Alzheimer’s disease and other related dementias.

FinnBrain imaging study explores brain structure in newborns

Infant brain development is still poorly understood. Thus, research on the topic is vital as developing brains are sensitive to early environmental factors. Recognizing this, the FinnBrain imaging study conducted in Turku explores brain structure in newborns.

Long spaceflight causes structural changes in the brain

Spending long periods in space not only leads to muscle atrophy and reductions in bone density, it also has lasting effects on the brain. However, little is known about how different tissues of the brain react to exposure to microgravity, and it remains unclear whether and to what extent the neuroanatomical changes so far observed persist following return to normal gravity.
