Okay, you've completed a whirlwind tour of the fundamentals of brain ischemia. You've come pretty far, and you owe yourself a pat on the back. Maybe a break to stretch your legs. Perhaps a hot chocolate or cappucino. Maybe with one of those little crunchy biscotti thingies with the little dark chocolate nuggets inside. If you're lucky enough, maybe you can even convince somebody to give you a foot massage. Go ahead. I'll wait.

Figure. Take a short break. You deserve it. You have 3 minutes.
