The more neuroscience related ECs you can add, and the more advanced those activities, the better.
At least one of your LORs should come from a STEM teacher. It would be a major hole without it. They want to know you can excel in college-level science classes. They don’t care what a wonderful active student you were in French.
I don’t know neuro that well, but I’d suggest looking at Boston University, Wesleyan, University of Chicago, Johns Hopkins, Northeastern and Northwestern, Emory, Boston College, Tulane, University of Rochester, to name a few.
Those schools would generally be the “high matches / low reaches” for you.
