‘Error neurons’ play role in how brain processes mistakes

New research from Cedars-Sinai has identified neurons that play a role in how people recognize errors they make, a discovery that may have implications for the treatment of conditions including obsessive-compulsive disorder and schizophrenia. Catching even small errors, such as making a typo while writing a letter, is a critical executive function that allows us […]

Advanced imaging technology measures magnetite levels in the living brain

Investigators at the Martinos Center for Biomedical Imaging at Massachusetts General Hospital (MGH) have used magnetoencephalography (MEG) – a technology that measures brain activity by detecting the weak magnetic fields produced by the brain’s normal electrical currents—to measure levels of the iron-based mineral called magnetite in the human brain. While magnetite is known to be […]

Researchers hope to be able to replace dysfunctional brain cells

A new study by researchers at Karolinska Institutet supports the theory that replacement of dysfunctional immune cells in the brain has therapeutic potential for neurodegenerative diseases like ALS and Alzheimer’s disease. The study, which involved repopulating the brain with new immune cells in an experimental disease model, is published in Nature Communications. Macrophages are immune […]

Automated detection of sleep states from olfactory brain waves

Scientists have developed a completely automated technique for real-time detection of sleep/wake states in freely moving mice. Conducted by Karim Benchenane, Sophie Bagur and colleagues at the National Centre for Scientific Research in Paris, the study, publishing on November 8 in the open-access journal, PLOS Biology, describes how local brain activity in the olfactory bulb […]

Old drug, new hope for pediatric brain cancer

Some drugs for heart disease might also work against brain cancer, according to an analysis by researchers from the Jackson Laboratory (JAX), Connecticut Children’s Medical Center (CCMC), and UConn Health. The researchers used a new approach to identify five heart medicines that might also be effective at fighting the most common type of childhood brain […]

AHA: Heart Health’s Impact on Brain May Begin in Childhood

TUESDAY, Oct. 23, 2018 (American Heart Association) — A child’s blood pressure could indicate cognition problems into adulthood, according to a new study suggesting the cardiovascular connection to cognitive decline could begin much earlier in life than previously believed. The findings may provide a window into the roots of dementia, for which high blood pressure […]
