Assessment of the dynamics of human glymphatic system by near-infrared spectroscopy.

abstract：:Initially, it has been shown that the phase thickness and refractivity (the latter interpreted as the difference of the refractivity indices of an object and surrounding medium) depend on the functional state of mitochondria. The refractivity of various objects decreased in response to energy depletion. This dependenc...
