Unusual days signal rising migraine risk
Harvard Medical School researchers report that higher day-to-day "trigger surprisal" scores were associated with migraine attacks over the next 12 and 24 hours. In this cohort, higher surprisal scores aligned with greater ...
Neural 'barcodes': Intra-regional brain dynamics linked to person-specific characteristics
People can think, behave and function very differently. These observed differences are known to be the result of complex interactions between genetics, neurobiological processes and life experiences.
Hypertension affects the brain much earlier than expected, study suggests
Hypertension impairs blood vessels, neurons and white matter in the brain well before the condition causes a measurable rise in blood pressure, according to a new preclinical study from Weill Cornell Medicine investigators. ...
