based purely off of my own interest in the course, I think technically yes you can get into the course without neuroscience (depending on the uni some require biology, some need either biology or chemistry I think) although again based off my own research into the courses a lot of the more basic stuff is covered within biology A-level (like the structure and function of the nervous system) so you'd be behind others who did take biology at a level.
but yes - like above you're best looking at entry requirements/foundation years and even asking students who study the course!
