In everyday listening\, the pitch and rhythm of speech and music blend to gether to create a seamless perception of pitch fluctuations organized in time. The organization of pitch in rhythm aids cognitive processing in b oth domains. An extensive body of research has shown that music training leads to brain plasticity such as enhanced perception and processing of p itch and rhythm\, as well as spoken and written language. However\, the n euronal mechanisms of pitch and rhythm are often the investigated separat ely and the interrelationship between tone and rhythm processing is only beginning to be explored. In this study\, we used EEG and ERP time-frequ ency analysis methods\, developed in animal and human adult experiments\, to evaluate the contribution of cortical oscillations to typical infant auditory development. By comparing the frequency composition of neural r esponses to auditory tone sequences\, we are able to disentangle the temp oral dynamics of pitch and rhythm representation. The results of this investigation suggest that there may be specific mechanisms for simultane ous processing of complex auditory representation. We also advance the hy pothesis that the peripheral pathways carrying largely segregated represe ntations of tonal “content” (e.g. pitch) and “context” (e.g. rhythm) feed into separate thalamocortical systems that could integrate tone content within rhythm context in auditory cortex. This hypothesis provides a fram ework for generating testable predictions about the early stages of music processing in the human brain\, and may also be useful for understanding how the neuronal “context” of rhythm can facilitate music-related plasti city. Because the thalamocortical circuit is shared in both speech and mu sic processing\, our data and hypothesis also provide a substantive expla nation of why music lends itself to plasticity in speech encoding mechani sms.
