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.
