Research Abstract

We investigated whether FBC has a favorable effect on focal cerebral ischemia (FCI). Under general anesthesia, a small burr-hole was made and FCI was induced in the rat primary sensorimotor area (SI-MI) using photothrombosis. After that, FBC was performed. We report the novel finding that epileptiform discharges were suppressed in the ischemic border, the infarct area was reduced and neurobehaviour was preserved by FBC.
