Professor of Translational Neurobiology at University of Copenhagen. Research interests are brain aging, blood-brain barrier, drug delivery, brain blood vessels, brain energy and metabolic water and cortical spreading depolarization.
Your brain functions not only as a thinking organ but also as a miniature water factory. We here calculate how much water neuronal mitochondria produce by glucose oxidation: 300-400 ml. Of that amount, 100 ml go into brain's interstitial fluid. fluidsbarrierscns.biomedcentral.com/articles/10....

Maintaining brain fluid homeostasis is of critical importance for creating a stable environment conducive to optimal neuronal functioning, nutrient distribution, and waste product removal. In this stu...

The cerebral blood flow response to neuroactivation is reduced in cognitively normal men with β-amyloid accumulation - Alzheimer's Research & Therapy
Background Accumulation of β-amyloid (Aβ) in the brain is a hallmark of Alzheimer’s Disease (AD). Cerebral deposition of Aβ initiates deteriorating pathways which eventually can lead to AD. However, t...
