I guess it isn't that surprising. Both constructed languages and natural languages are man-made and do the same thing, it's just that they were developed by different processes.<p>Conlangs also tend to be based, consciously or subconsciously, on existing natural languages. As I understand, Esperanto is largely Romance language vocabulary with Slavic language grammar.

I’m excited for the Lojban work:<p>> To further refine the features of language that activate the brain’s language network, Fedorenko’s lab is now planning to study how the brain responds to a conlang called Lojban, which was created by the Logical Language Group in the 1990s and was designed to prevent ambiguity of meanings and promote more efficient communication.
