Twenty years ago, I began my course work as a pre-medical student at Seattle University in Washington.  During my time in college, I worked as a research technician at the University of Washington-Dept of Neurology studying neurosyphilis. To elucidate more about the bacteria, Treponema pallidum, I would perform a variety of procedures on laboratory animals to reduce their pain.  By happenstance, the medication that I used regularly was ketamine!  I didn’t think much of it at the time, but a seed had been planted.
