News Finding: Brain rhythms, they add, therefore appear to play a role in parsing and grouping sound streams into "chunks" that are then analyzed as speech or music.
Paper Finding: In addition, higher-frequency activity merits scrutiny.
News Context: This difference, the researchers say, may suggest that non-musicians are unable to process the music as a continuous melody rather than as individual notes. Moreover, musicians much more accurately detected pitch distortions--as evidenced by corresponding cortical oscillations. Brain rhythms, they add, therefore appear to play a role in parsing and grouping sound streams into "chunks" that are then analyzed as speech or music.
Paper Context: Overall, the data suggest that, although cortical entrainment is necessary to support intelligibility of continuous speech-perhaps by parsing the input stream into chunks for subsequent decodingthe reverse does not hold: "intelligibility" is not required to drive entrainment. In addition, higher-frequency activity merits scrutiny. Furthermore, prestimulus beta plays a role in generating accurate temporal predictions even in pure listening tasks .
