You stand up after an hour-long lecture, and your vision goes black. You panic. Are you dying??? Do you need to go to the hospital?? Did you eat lunch?? Are you still conscious?? (Probably not, probably not, probably not, and yes. Thankfully, your vision clears quickly.) It's important to be able to recognize emergencies when they occur, but we don't want to make mountains out of molehills. Luckily, the human brain typically displays a few key symptoms for serious damage. In this class, you'll learn what to look out for in yourself and others - and what to do should an emergency occur. We'll also explain the science behind these issues within the brain and nervous system as time allows.
