Berlin Brain 2017
Dawid Borycki presented a poster entitled Interferometric near-infrared spectroscopy (iNIRS) quantifies brain absorption, scattering, and blood flow index in vivo. The presentation was devoted to explain a new noninvasive method for quantifying optical (absorption and scattering) and dynamical (blood flow index, BFI) properties of the brain. These are ongoing goals of near-infrared and diffuse correlation spectroscopies.
Dawid Borycki demonstrated that iNIRS can simultaneously quantify optical properties and BFI of the nude mouse brain during hypercapnia challenge by showing measured representative temporal point spread functions of light scattered from the brain and fits with diffusion theory. He showed that absorption increases during hypercapnia, while BFIs for three distinct path lengths suggest that vasodilation during hypercapnia leads to increased cerebral blood flow.
This poster presentation was also utilized to announce research results to broad audience of neuroscientists and interact with numerous researchers from top scientific institutions, e.g. University of Cambridge (UK), The Institute of Photonic Sciences (Spain), Harvard Medical School (USA).
