NEUROGENIC HYPERTENSION: REPORT OF FIVE CASES TO HIGHLIGHT THE CONTROVERSY
The entity of "neurogenic hypertension" is defined as arterial hypertension caused explicitly by derangement of the intricate network of the central nervous system.

متن کاملThe coupling controversy
Functional magnetic resonance imaging (fMRI) relies on the well-known phenomenon of coupling between neuronal activity and brain blood flow. For nearly a century, the presumption was that hemodynamics were coupled to neuronal activity via energy demand and oxidative metabolism. Early (15)O positron-emission tomographic (PET) studies challenged this theory, demonstrating a physiological "uncoupl...
