Many facets of human behaviour are rhythmic. Examples include singing, playing an instrument, or dancing, but also – perhaps less obviously – spoken language. First, we investigate the neuronal underpinnings of rhythmicity in humans. Using the example of speech, we aim to better understand the role of rhythmic neuronal activity in speech comprehension. Second, we use an animal model (songbird) to test whether rhythmicity, as observed in speech and music, is specific to human cognition – or plays a more general role in communication.
