A Low-Budget Photothrombotic Rodent Stroke Model.

A number of animal stroke models have been developed and used over the years to study the pathological mechanisms of this disorder and develop new therapies. Among them, the photothrombotic model of ischemic stroke has been central in various studies focusing on understanding of the basic biology of neural repair, identification and validation of key molecular targets involved in post-stroke recovery, and preclinical testing of various therapeutic approaches. To facilitate uniformity among various experimental groups using this expert-recommended mouse model of choice for stroke recovery studies, in this chapter we describe in detail a low-budget technique to induce photothrombosis in the mouse primary motor cortex. Additionally, we provide tips for conducting this procedure in other cerebral cortical regions of the mouse brain and in rats.
