Are cortical oscillations a useful ingredient of speech processing?

Neuronal oscillations are ubiquitous in the brain and may contribute to cognition in a number of ways, for example by segregating information and organizing spike timing. Recent data show that delta, theta, and gamma oscillations are specifically engaged by the multi-timescale, quasi-rhythmic properties of speech and can track its dynamics. We will discuss the role they could play in speech and language processing, for instance by 'packaging' incoming information into units of the appropriate temporal granularity, and by temporally organizing the neural code. Finally we show how disruptions of auditory cortical oscillations can affect language development.
