Blood Type Tied to Early-Onset Stroke Risk
Two variants in ABO, a known stroke locus, were linked with early-onset ischemic stroke risk, a meta-analysis of genome-wide association studies (GWAS) showed. The variants tagged blood type subgroups O1 and A1, and effect sizes were significantly larger in early-onset (under age 60) than late-onset stroke, reported Braxton Mitchell, PhD, MPH, of University of Maryland […]
Neuroscientists posit that brain region is a key locus of learning
Small and seemingly specialized, the brain’s locus coeruleus (LC) region has been stereotyped for its outsized export of the arousal-stimulating neuromodulator norepinephrine. In a new paper and with a new grant from the National Institutes of Health, an MIT neuroscience lab is making the case that the LC is not just an alarm button but […]
