Can brain lesions contribute to criminal behavior?

New research published in the Proceedings of the National Academy of Sciences indicates that lesions to brain areas in individuals exhibiting criminal behavior all fall within a particular brain network involved in moral ...

New biomarkers of multiple sclerosis pathogenesis

Multiple sclerosis (MS) is a chronic debilitating inflammatory disease targeting the brain. The pathogenesis of MS remains largely unknown, though brain tissue damage in MS is likely due to immune cells attacking myelin basic ...

Hypoxia reverses mitochondrial disease in mouse model

The next stage of a Massachusetts General Hospital (MGH) team's investigation into the therapeutic potential of the hypoxia response - the body's reaction to reduced levels of oxygen in the blood - to treat mitochondrial ...

Brain damage is not always damaging

Stroke is a type of lesion caused by reduced blood flow to the brain, which results in the death of some of the brain's neurons. Such lesions typically cause severe difficulties for the person who endures them. We base this ...

Device reduces risk of brain injury after heart valve replacement

Among patients with severe aortic stenosis (narrowing of the aortic valve) undergoing transcatheter aortic valve implantation, the use of a cerebral protection device (a filter that captures debris [tissue and plaque] dislodged ...
