View full lesson:

When under anesthesia, you can’t move, form memories, or — hopefully — feel pain. And while it might just seem like you are asleep for that time, you actually aren’t. What’s going on? Steven Zheng explains what we know about the science behind anesthesia.

    Yeah, I just had surgery last week, and have had numerous surgeries, and NO one ever told ME to count backwards, they just told me they were going to give me something to relax me, and the next thing I knew was they were calling my name, waking me up and telling me, "it's all over".

    So, in a nutshell, this is what I gathered from this video: "How does anesthesia work? We are not really sure, but here's what we believe to be happening...". I have had several general-anesthesia surgeries, but after hearing that we're not even sure how this stuff works, it gives me a whole new respect for those who performed my procedures.
