The medical center was very modern, facilities are great!
What impressed you negatively?
The letter grading system (I'm back in college again?). One student went on a tirade about how much she hated her neuro class, and how badly it was taught. In general the maturity level of the students was extremely low; there were numerous gay jokes. The Dallas area is very much a "strip mall".
What did you wish you had known ahead of time?
That the information on their webpage regarding programs in neuroscience was outdated/incorrect (I was contradicted often by a director when mentioning some of these programs). That one of their nobel laureate directors (Rodney Ulane) is leaving for NYU.
