Abstract
The brain is a metabolically demanding organ and its health directly depends on brain oxygen dynamics to prevent hypoxia and ischemia. Localized brain tissue oxygen is characterized by a baseline level combined with spontaneous oscillations. These oscillations are attributed to spontaneous changes of vascular tone at the level of arterioles and their frequencies depend on age. Specifically, lower frequencies are more typical for neonates than for adults. We have built a mathematical model which analyses the diffusion abilities of oxygen based on the frequency of source brain oxygen oscillations and neuronal demand. We have found that a lower frequency of spontaneous oscillations of localized brain tissue oxygen can support higher amplitudes of oxygen concentration at areas distant from a source relative to oscillations at higher frequencies. Since hypoxia and ischemia are very common events during early development and the neurovascular unit is underdeveloped in neonates, our results indicate that lower frequency oxygen oscillations can represent an effective passive method of neonatal brain protection against hypoxia. These results can have a potential impact on future studies aiming to find new treatment strategies for brain ischemia.
