For Neuro, I would try to stick to the bigger cities where you can actually find a neurologist to rotate with. Because a formal Neuro rotation is not required for most DO schools including ARCOM, you can use your electives to set your own neuro rotations before actually going out for auditions in early 4th year. I was in Little Rock and was able to get some good experience there. NWA and Shreveport would be reasonable too I would think, although I’m not too familiar with those sites.
Edit: Also good to note that the only Neuro residency in Arkansas is in Little Rock (UAMS). If you wanna rotate there for an audition, it may be easier if your core is in Little Rock. There’s also more volume and more opportunities in general being in a metropolitan area even though LR is not really that big (but that’s as big as it gets in AR).
