| 2 | Characterization of cerebral blood flow dynamics with multiscale entropy显示文摘Based on the laser speckle contrast imaging(LSCI)and the multiscale entropy(MSE),we study in this work the blood flow dynamics at the levels of cerebral veins and the surrounding network of microcerebral vessels.We discuss how the phenylephrine-related acute peripheral bypertension is refected in the cerebral circulation and show that the observed changes are scale dependent,and they are signifcantly more pronounced in microcerebral vessels,while the macrocerebral dynamics does not demonstrate authentic inter-group distinctions.We also consider the permeability of blood-brain barrier(BBB)and study its opening caused by sound exposure.We show that alterations associated with the BBB opening can be revealed by the analysis of blood flow at the level of macrocerebral vessels. | Alexey N.Pavlov Arkady S.Abdurashitov Olga N.Pavlova Maria V.Ulanova Anastasia A.Bodrova Natalia A.Shushunova Alexander P.Khorovodov Oxana V.Semyachkina-Glushkovskaya | 2017 | Journal of Innovative Optical Health Sciences2017，，5： | 0 |
