Unlocking the Future: Severance’s Neurosurgery Expert Reveals How Near We Are to Revolutionary Tech

What if you could completely disconnect your work life from your personal life? This intriguing question lies at the heart of the Apple TV+ series Severance, which has recently concluded its second season.

In the show, employees at a company called Lumon undergo a procedure that implants a microchip in their brains to separate their work and personal memories. This means they won’t bring work home, but it comes at the cost of their personal identity. The concept raises fascinating ethical and scientific questions about memory, identity, and how technology could reshape our reality.

To make the show’s science feel authentic, the creators consulted with Vijay Agarwal, a neurosurgeon and chief of the Skull-Base Tumor Center at Montefiore Einstein. He worked alongside the show’s creators to ensure the portrayal of the severance procedure was as believable as possible.

Agarwal shared some thought-provoking insights into the current state of neuroscience. He pointed out that we are closer than ever to implanting devices in the brain to alter its functions. In fact, procedures that stimulate brain activity to help patients regain motor function are already happening. For instance, scientists now use deep brain stimulation to treat conditions like Parkinson’s disease, effectively showing how they can intervene in brain signals.

“The idea of modifying brain functions through technology used to seem like science fiction,” Agarwal noted. “But now it’s a part of our reality.” This brings a sense of urgency to the themes explored in Severance.

The series also touches on the emotional aspects of memory. Agarwal highlighted that memories tied to emotions, particularly those involving the amygdala and hippocampus in the brain, could be manipulated with advanced technology. The fact that viewers are intrigued by these concepts reflects a broader societal curiosity about how technology could impact our emotional landscapes.

Fans of Severance are buzzing with theories and discussions about the show, much like readers dissecting a captivating novel. The show inspires deep conversations around identity, mental health, and what it means to be human in a tech-driven world.

As an illustrative example of how medical interventions can affect brain function, Agarwal referenced real procedures that enable paralyzed patients to regain movement. These scenarios beg questions about control and ethics—who gets to decide when and how these interventions take place?

In season two, the complexities of "reintegration," or merging severed identities, are more pronounced, prompting further discussion on what modern neuroscience might reveal. While some viewers might find these concepts far-fetched, Agarwal reassures that many themes in Severance are not as far from scientific reality as one might think.

The show is not just a fictional exploration; it mirrors the dilemmas we face in today’s tech-centric society. As we evolve technologically, the ethical and personal challenges will inevitably grow. Conversations using platforms like Severance create valuable spaces for reflection and dialogue—ultimately about who we are and who we want to be in the face of rapid change.
