Plastic Change along the Intact Crossed Pathway in Acute Phase of Cerebral Ischemia Revealed by Optical Intrinsic Signal Imaging

Figure 2

Laser speckle imaging (LSI) and triphenyltetrazolium chloride (TTC) staining results of photothrombosis. LSI images before (a) and after (b) photothrombotic stroke. The flow in the vessel (see the arrow area) apparently disappeared immediately after the thrombi formed, indicating the success of stroke model. The color map stands for the relative speed of blood flow, and the circle shows the main affected area due to ischemia. Representative TTC stained coronal sections of brain slices in Control group (c) and Stroke group (d). Unstained area depicts infarcted S1HL after photothrombotic stroke.
