Quoting from the article:

"Take, for instance, a loop ..."

Personally, I write most programs in a logic programming language that has no loops. I wonder whether the engaged brain areas also depend on the programming language. The previous study used for example Python, an imperative language, and mentiond "Language system responses during code comprehension are weak and inconsistent":

Could it be that language system responses are stronger for more declarative programming languages, where a clear description of the problem is of greater importance?
