The Neuroscience of Learning Elvish: What Conlangs Reveal About the Brain
In 2025, MIT researchers published fMRI data showing that Klingon, High Valyrian, and Esperanto activate the same neural circuits as English or Mandarin — the same brain regions that process natural human languages developed over thousands of years. A constructed language invented a decade ago by a screenwriter activates the identical network as a language shaped by centuries of use. This finding tells us something fundamental about how the brain decides what counts as a 'real' language — and it has practical implications for how anyone, at any age, learns any language, fictional or otherwise.
