I would suggest..choose the mentor who you think you would work best with. A lot of PIs that I talked to say that it doesn't matter exactly where you go but what you do. Best of luck!
I applied to neuroscience PhD programs, and now I need to make a decision. I have narrowed it down to three schools: Texas A&M BCN, University of Florida IDP, and UAB Neuroscience. Out of the three, where would you go? Good luck making the decision!
