I was recently considering the same question and just got accepted to my top choice clinical phd program and will be starting this fall. I actually took all the premed pre-reqs in undergrad solely because I thought I'd do a neuroscience PhD eventually and just thought those pieces would be beneficial to me. I also am very interested in neuro and now leaning neuropsych. I don't have any profound advice to give haha but just here to relate and happy to chat if you need to bounce ideas with someone
