Hendrik Purwins is co-author of a work that will be presented at the conference “The Neurosciences and Music” in Dijon 29th of May- 1st of June
2014. Title: The polyphonic brain: Extracting the neural representation of rhythmic structure for separate voices of polyphonic music using ERPs.
Rapid changes in the stimulus envelope (indicating tone onsets) elicit an N1-P2 ERP response, as has been shown for clicks and sine waves, musical tones and for speech. Canonical Correlation Analysis with temporal embedding (tkCCA), a multivariate correlation-based method, allows to extract brain responses to these changes in continuous auditory stimuli.
