Title of the lecture: Optical imaging of cerebral blood flow: advantages of lasers
Keywords: vascular tree, laser-based techniques
Summary: Imaging of cerebral blood flow and microcirculation is essential for understanding the physiology and pathophysiology of the central nervous system. Brain is situated in the bony skull and the structure and arrangement of the blood vessels is very complex therefore it has been difficult task to investigate the structure of the vascular tree and dynamics of the blood flow. Before the laser based techniques had been invented the optical methods had serious limitation. During the last 30 years, laser-based techniques (laser Doppler measurement, laser speckle analysis, two and multiphoton microscopy etc.) have completely changes our view on this very complex system. Our group has been studying cerebral circulation with multi- modal imaging techniques for decades. In this talk I will show the most important, non-invasive optical methods used in our laboratory. We have been studying the basic mechanisms behind various types of brain injuries including stroke or hypoxia.
