Revealing Brain Function by Measuring Blood Flow and Oxygenation with Light
with private browsing in FireFox
Over the last 25 years, various spectroscopic, Doppler, interferometric, and lifetime based optical measurement technologies have been developed for investigating brain function in humans and in animal models. My research has focused on developing and applying methods to measure cerebral blood flow and oxygenation. I will start by describing the development of functional near infrared spectroscopy of hemoglobin oxygenation and diffuse correlation spectroscopy of blood flow for measuring human brain function. I will then review the development of laser speckle contrast and multi-spectral optical intrinsic signal imaging for exploring the relationship between blood flow and oxygenation with neuronal activity in animal models, enabling us to better interpret human brain function measurements, including those made with functional magnetic resonance imaging. I will then discuss the development of two photon microscopy and optical coherence tomography methods for advancing the spatial resolution with which blood flow and oxygenation can be measured. I will couple descriptions of each of these technological developments with examples of their impactful applications.
