It was interesting to read. There aren't many google results for 'multiple demand network' that I could easily parse, but I did happen to find this paper on it in primates[0] (also happens to be from MIT) when I was trying to find an image that showed what parts of it are activated. I found this slide from a lecture very interesting[1].

You are right, that slide is very interesting indeed. I wonder what it is about the different languages that triggers the brain to use different regions?

It's probably noise.

Or it could be a sign that logogram-based writing is handled in a different way than one based on a phonetic alphabet.
