If, by ‘Babel’, we mean the set languages that have appeared in the world, we may want to research the ‘boundaries of Babel’ by asking whether the expansion of Babel is prevented (i.e., whether unobserved languages are impossible languages), and, if so, by which factors. The boundaries of Babel are being explored by partnerships of linguists and neuroscientists. Neo-chomskian approaches find evidence of neural networks dedicated to language processing, and study how these networks constrain the space of possible grammars, whereas lexico-grammar looks at neuroscientific evidence that syntax is not a separate function in the brain. Research questions also expand beyond a tight focus on the brain-language relationship. By ‘foundations of Babel’ we refer to broader, ancient brain functions in which articulated language is embedded. Imitation can be one of those functions. ‘Physics of Babel’ refers to many extra-brain factors that are lacking in non-human species, and that together make language possible. Research on the boundaries of Babel is a fascinating and open scenario, not only interdisciplinary, but also multi-directional, beyond the language function and beyond the exclusive role of the brain.
