"Neural Signatures of the Processing of Temporal Patterns in Sound" by Bjorn Herrmann and Ingrid Johnsrude has been published in the Journal of Neuroscience. Check it out here: http://www.jneurosci.org/content/38/24/5466.long
About the paper: Optimal perception requires that the auditory system detects regularities in sounds. Synchronized neural activity and increases in sustained neural activity both appear to index the detection of a regularity, but the functional interrelation of these two neural signatures is unknown. In three electroencephalography experiments, we measured both signatures concomitantly while listeners were presented with sounds containing frequency modulations that differed in their regularity. We observed that both neural signatures are sensitive to temporal regularity in sounds, although they functionally decouple when a listener is distracted by a demanding visual task. Our data suggest that neural synchronization reflects a more automatic response to regularity compared with sustained activity, which may be influenced by attentional, contextual, or other experiential factors.
Congratulations, Bjorn and Ingrid!
