Abstract

We demonstrate the simultaneous imaging of cortical blood flow and haemoglobin oxygenation of the exposed cortex in rats using laser speckle contrast analysis (LASCA) and RGB reflectometry. Spatial and temporal resolved changes in blood flow and oxygenation are observed for single forepaw stimulation.
