ADHD medication may affect brain development in children

A drug used to treat attention-deficit/hyperactivity disorder (ADHD) appears to affect the development of the brain's signal-carrying white matter in children with the disorder, according to a study published in the journal ...

Obesity linked with differences in form and structure of the brain

Researchers using sophisticated MRI technology have found that higher levels of body fat are associated with differences in the brain's form and structure, including smaller volumes of gray matter, according to a study published ...

Study: Protein key to charcot-marie-tooth, other nerve diseases

A new study provides critical insight into a little-known, yet relatively common, inherited neurological condition called Charcot-Marie-Tooth disease. The findings point to a pathway to possible treatments for this disease ...

Alcohol-induced brain damage continues after alcohol is stopped

Although the harmful effects of alcohol on the brain are widely known, the structural changes observed are very heterogeneous. In addition, diagnostic markers are lacking to characterize brain damage induced by alcohol, especially ...

Researchers identify brain protein crucial to recovery from stroke

Every 40 seconds, someone in the United States suffers a stroke and available therapies, such as clot busting drugs or clot removal devices, are focused on limiting the extent of brain damage. Now, research from the University ...

White matter

White matter is one of the two components of the central nervous system and consists mostly of myelinated axons. White matter tissue of the freshly cut brain appears pinkish white to the naked eye because of myelin is composed largely of lipid and a few percent of capillaries. Its white color is due to its usual preservation in formaldehyde. A 20 year-old male has around 176,000 km of myelinated axons in his brain.

The other main component of the brain is grey matter (actually pinkish tan due to blood capillaries). A third colored component found in the brain that appears darker due to higher levels of melanin in dopaminergic neurons than its nearby areas is the substantia nigra.
