معرفی
Martin Lauritzen is a Professor in the Department of Clinical Medicine, specifically within the Neurology Center for Healthy Aging Damage and Repair, and also holds a Professor position in the Department of Neuroscience focusing on Neuronal Signalling at the University of Copenhagen's Faculty of Health and Medical Sciences. With an extensive publication record of 223 research outputs, his work spans multiple disciplines within neuroscience and neurology, with particular emphasis on brain aging, neurovascular coupling, and cerebral blood flow regulation. His research has garnered significant attention, including media coverage of his work on brain fluid dynamics during sleep.
Professor Lauritzen's primary research interests focus on the intricate relationship between brain function and vascular dynamics. His work explores how neurovascular coupling changes with age, the mechanisms underlying cortical spreading depression in migraine, and the role of the blood-brain barrier in neurological disorders. He has made significant contributions to understanding how sleep affects brain fluid dynamics and waste clearance, with his 2019 research on 'brain rinse cycle' during sleep receiving widespread media attention. His investigations into cerebrovascular responses in early Alzheimer's disease, particularly regarding amyloid-β accumulation and its effects on cerebral blood flow, represent a critical frontier in dementia research. Lauritzen's laboratory employs advanced techniques including two-photon microscopy, in vivo imaging, and electrophysiological recordings to study neuronal and vascular function in awake animal models.
Analyzing his recent publication trends (2023-2025), Lauritzen's research demonstrates a clear trajectory toward understanding age-related changes in brain vasculature and their cognitive implications. His work bridges basic neuroscience with clinical applications, particularly in the areas of migraine pathophysiology, Alzheimer's disease biomarkers, and brain aging. A significant portion of his recent work focuses on the role of precapillary sphincters and pericytes in regulating cerebral blood flow, especially in aging brains. His research also explores cognitive reserve factors in longitudinal population studies, connecting vascular health with cognitive outcomes in aging populations. The interdisciplinary nature of his work is evident in publications spanning from instrument development to clinical studies of cognitive aging in the Danish Metropolit 1953 male cohort.
Professor Lauritzen has been involved in significant collaborative research efforts, particularly evident in his work with S. Grubb on sleep-related brain fluid dynamics, which generated substantial media coverage across multiple outlets. His work with the Metropolit 1953 Danish male cohort indicates involvement in long-term population studies examining cognitive aging and vascular health.
Based at Blegdamsvej 3B in Copenhagen, Lauritzen leads research teams studying neurovascular function, particularly focusing on the aging brain. His work with two-photon microscopy and in vivo imaging suggests a well-equipped laboratory capable of advanced neuroimaging techniques. The breadth of his collaborations, evident from co-authorship patterns across numerous publications, indicates an active research group with connections across neuroscience, neurology, and gerontology disciplines.
