The brain is a precision instrument. Its function depends on finely calibrated electrical activity triggering the release of chemical messages between neurons. In an epileptic brain, the neurons fire wildly. Credit: Sergey Nivens/Shutterstock.com But sometimes the brain’s careful balance is knocked out of control, as in epilepsy. Electroencephalography, or EEG, visualizes a brain’s electrical activity and...

Detailed atlas of the nervous system
Researchers at Karolinska Institutet have created a systematic and detailed map of the cell types of the mouse nervous system. The map, which can provide new clues about the origin of neurological diseases, is presented in the journal Cell. The researchers will now use the same methods to map out the human brain on a detailed level. The nervous...

Mindful brains
In the world with so much buzz around us, it can be difficult to unplug from work and not think about the never-ending list of things to do. Stress accumulates…. If you can relate to these statements (let’s be honest, most of us will), you might search for ways to de-stress, and people are becoming...

1 in 8 children in India has neurodevelopmental disability, report estimates
(CNN)Nearly one in eight Indian children ages 2 through 9 might have a neurodevelopmental disorder, a new report by the INCLEN Trust International estimates. The Delhi-based medical research organization highlighted the number as a significant health burden. Experts say the study is the first to provide insight into the prevalence of neurodevelopmental disorders, including hearing impairment, epilepsy and learning...

New stem cell model can be used to test treatments for a rare nervous system disorder
A City of Hope researcher has developed a stem cell model to assess possible treatments for a rare nervous system disorder that is in the same disease group as Alzheimer’s disease, Parkinson’s disease and amyotrophic lateral sclerosis (ALS). An Alexander disease patient’s stem cell-derived astrocytes (green) inhibits the growth of precursor cells that become myelin...

Soccer heading may be riskier for female players
RADIOLOGICAL SOCIETY OF NORTH AMERICA OAK BROOK, Ill. – Researchers have found that women who play soccer may be more at risk than their male counterparts. According to a new study published in the journal Radiology, female soccer players exhibit more extensive changes to brain tissue after repetitive ‘heading’ of the soccer ball.

Study provides insight into how dying neurons control eating behaviors of the brain microglia
July 23, 2018, The Mount Sinai Hospital A new Mount Sinai study, published July 23 in the journal Nature Neuroscience, provides important insight into how microglia, cells that form a branch of the immune system inside the brain, go about their job of clearing out dying and non-functional neurons—and how they sometimes mistakenly attack healthy neurons, an...
