Severance’s Consulting Neurosurgeon Explains the Science behind the Show’s Brain Procedure

Science Quickly

What if you could completely separate your work and personal life—with the help of a brain implant? That’s the unsettling premise of Severance, the hit Apple TV+ show that just wrapped its second season. To make the science fiction feel as real as possible, the creators brought in an actual neurosurgeon, Vijay Agarwal, chief of the Skull-Base Tumor Center at Montefiore Einstein, as a consultant for the show. Host Rachel Feltman met with Agarwal to break down the real neuroscience behind Severance—and whether a procedure like the one it depicts could ever exist.

Mild spoilers ahead! We recommend you at least watch through episode seven of season two before you listen.
