How Breathing and Cardiac functions interact with Cerebral arterio-venous blood flows: Origin of CSF oscillations

Résumé

Motivation The main drivers of CSF oscillations are currently controversial. Goal To investigate whether the breathing or cardiac regulated Cerebral blood flow are the major driver of CSF dynamics. Approach Investigate Cerebral blood and CSF flows through the intracranial compartment during free and deep breathing using real-time phase-contrast sequence. To quantify the neurofluids volume displacement along the cardiac cycle. Results Both cardiac and breathing cycles influenced neurofluids volume displacements. CSF dynamics is significantly correlated with intracranial blood volume change. CSF dynamic acts as a compensatory mechanism of intracranial blood volume dynamics.
