Mayim Bialik, who plays Dr. Amy Farrah Fowler, is actually a neuroscientist.
The cast has admitted to having a little trouble memorizing their lines and pretending that they actually know what they were talking about, especially when they have to say physics terms and other brainy words. But not Mayim Bialik! The actress, who plays Sheldon’s love interest Dr. Amy Farrah Fowler on the show, is actually a neuroscientist and is the only cast member with a PhD! Bialik once admitted to correcting her script based on her own knowledge. Cool!
