Interesting point. They usually have to do some science or clinical research while in residency, as well.
They do, and usually they have to learn some science or participate in clinical research for residency.
I once thought about becoming a neurosurgen, but you probably have to go to school for a long time. Oh, really? I do know that neurosurgeons are also called brain surgeons. Being a neurosurgeon also seems like a very stressful job that not everyone could do! Well, a neurosurgeon has to be able to deal with disorders involving all parts of the nervous system. Oh wow! I can't imagine what people had to go through before brain surgery was invented! When was it invented, by the way? I'm not sure, but you need at least seven years after graduating from med school of training. Oh wow! I figured as much! That was the one major thing preventing me from going to school for it! Ah, I see. In the US, neurosurgeons usually do 4 years of undergrad, 4 years of med school, and finally 7 years in residency. I sure hope we never have a shortage of brain surgeons! They do a very important job.
Most, but not all, residency programs have some component of basic science or clinical research.
