yes, you absolutely can. don't listen to the mean responses on this thread. if it was neuroscience, then it is biology. not all neuro classes are jokes, even if they are in the psych department. in a lot of schools you can pursue a neuro degree through either the psych or bio depts.
med schools recognize that neuroscience classes are not straight psych classes, but involve a lot of biology (at least mine did) and so you can count them in your science gpa.
by the way, this is all coming straight from my pre-med advisor who really knows her stuff.
