There's been a variety of papers using MRI scans to show the brain restructuring itself during learning. This takes time. Mathematics and CS deal with abstraction upon abstraction, as well as counter-intuitive systems (negative numbers, unreal numbers, infinity just as a start), both of which I would suspect require more intense rewiring. I've taught CS to English grads, and entire classes can be spent trying to establish a single, simple (to me) concept.

But theresdefinitely more effective techniques than just exposure and time. Finding the smallest new knowledge beyond the students current (ie one thing at a time) can make a big difference. As does finding the right metaphor from within their current concepts, when adding a new one. But such things are harder to scale, being student centric, and most educations rely on some amount of scaling
