Our UHN programs and services are among the most advanced in the world. We have grouped our physicians, staff, services and resources into 10 medical programs to meet the needs of our patients and help us make the most of our resources.
University Health Network is a health care and medical research organization in Toronto, Ontario, Canada. The scope of research and complexity of cases at UHN has made us a national and international source for discovery, education and patient care.
Our 10 medical programs are spread across eight hospital sites – Princess Margaret, Toronto General, Toronto Rehab’s five sites, Toronto Western – as well as our education programs through the Michener Institute of Education at UHN. Learn more about the services, programs and amenities offered at each location.

What are the most promising treatments emerging to fight Covid-19? Can we create pacemaker stem cells and eliminate the need for surgically implanted electronic pacemakers? How do we leverage Artificial Intelligence to help us live longer at home? Is it possible to design a computer chip that monitors brain waves and stops epileptic seizures before they even happen?
Every day over 1,000 scientists at UHN pursue answers and solutions to the most profound health issues and diseases. For each and every researcher the pursuit of better treatments and discovering cures is personal. You can feel their passion in these intimate one-on-one conversations about their pioneering work and revealing personal stories of how they got to where they are today.

Episode 3 – Dr. Taufik Valiante invents computer chip designed to monitor and stop epileptic seizures
Air Date: November 3, 2020 | Length: 52:27
What if a tiny computer chip could be implanted into the brain to look out for epileptic seizures and then stop them before they ever occur? Sounds like science fiction – and yet – Dr. Taufik Valiante’s lab at the Krembil Research Institute has done just that. His chip is called ‘NURIP’ – the acronym for neural interface processor and it’s inspiration came from the engineering concept of control theory and applied to the brain.NURIP “is this idea that we can modulate, alter brain activity in a way to push the brain away from states that are bad for it, and epilepsy is just an example,” explains Dr. Valiante. NURIP is entering the animal model testing phase and if successful would be a game changer in the treatment of epilepsy.
