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. \[Directed by Zedem Media, narrated by Addison Anderson\].
