In previous work, Fedorenko and her students have found that computer programming languages, such as Python — another type of invented language — do not activate the brain network that is used to process natural language. Instead, people who read computer code rely on the so-called multiple demand network, a brain system that is often recruited for difficult cognitive tasks.

I’m curious if there’s some overlap between conlangs and programming languages, on the region level if not the network level. IIRC, the multiple demand network is a bit ill-defined and every region doesn’t necessarily activate for every task; and Fedorenko et al have their own idiosyncratic definition of the language network that omits anything that might also have other functions (including canonical regions like Broca’s and Wernike’s areas).
