"Medical psychology" really isn't conceptualized well and is not common. It means lost of different things to different people. Psychopharmacology, behavioral genetics, and neuropsychology (which includes neuroanatomy and other neuro heavy topics) are just some of the courses in my program that emphasize biology in clinical psychology. We have external practica in neuro departments, psychiatry departments, transplant and bariatric clinics, and other medical specialties of academic health centers and VAs. Yet, mine is not a "medical psychology" program. Conversely, since medical psychology is not a protected term, a program could feasibly call themselves a "medical psychology" program and have far less actual focus on the biological bases of behavior than my non-medical program.
