red blood cell traffic vs. oxygenation fluctuations

red blood cell traffic vs. oxygenation fluctuations

A composite illustration shows a blue-and-green graph of peaks in neural activity with a white fluctuating graph line trending down superimposed above it. A red blood cell graphic (top) and mouse brain graphic (top right) are also included.

The researchers found that red blood cell "traffic" (top grey bar) appears to contribute to oxygenation fluctuations (white line), which are not correlated to changes in neural activity (bottom blue peaks) in mice brains (top right).
