Overview
The middle cerebral artery (MCA) ligation technique is utilized to study focal cerebral ischemia in animal models. This method involves exposing and ligating the middle cerebral artery, resulting in reproducible infarct volumes and improved post-operative survival rates.
Key Study Components
