title: Motor mechanisms in speech ontogeny: phylogenetic, neurobiological and linguistic implications.
abstract: The rhythmic mandible-generated close-open alternations of the mouth, responsible for the series of consonant-vowel alternations characteristic of babbling and of languages, is receiving increased attention as a possible manifestation of an ontogenetic and phylogenetic 'frame' underlying the serial organization of speech. The supplementary motor area appears important for production of this consonant-vowel frame in adults.
