    Doppler optical coherence tomography for imaging of brain hemodynamics

    Advanced microscopic techniques enable depth-resolved imaging of changes in blood flow during brain activation. ptical imaging has become an important tool in neuroscience research.1 Using methods such as optical intrinsic signal imaging (OISI), laser-Doppler imaging, and laser-speckle imaging, investigators can record changes in blood flow and blood volume in the brain, as well as alterations in blood oxygen concentration, in response to different types of stimulation. By measuring these changes, they can gain deeper insight into the functioning of the brain, which in turn can contribute to better understanding of a range of behaviors and conditions. However, these techniques ...
