Some CNS pathways like corticospinal pathway and spinothalamic pathway cross over (left to right and vice versa). Is there any evolutionary logic to this? Wouldn't it be easier if all the tracts just took care of their respective sides in the body? eg right tracts responsible for temperate/pain/movements on the right, while left sided tracts take care of these functions in the left...
Why does the central nervous system pathways cross over?
