These links will take you to the Research Channel and specifically to lectures by Sean Mackey. He's a researcher/doctor at the Stanford Pain Clinic. He not only explains pain so very well but shares upcoming hopes for new treatments. One area of research is using functional MRI's and it's very interesting. I hope you enjoy listening to his lectures...I did, and I sure learned a lot also.
