The relation between oscillatory activity and predictions in multisensory sequence processing

This week a colleague from my research group send us an interesting paper for us to read that is a little bit related to our research, which is the following:

Dynamic Predictions: Oscillatory Mechanisms Underlying Multisensory Sequence Processing

Peng WangAlexander MayeJonathan DaumeGui XueAndreas K. Engel

In this study, Wang et al. used an audio-visual experimental design to investigate how intrinsically generated oscillatory signals are involved in predictions of stimulus sequences, and to what extent the coupling between different brain areas may relate to predictive processing.

These are some of the highlights that I found meaningful for our own research:

  • Behavioural performance correlated with phase-delays between remote regions in a network involving premotor and prefrontal (together with other) regions.
  • They found asymmetrical effects of attention to the visual and auditory modalities in the network, distinguished by changes in alpha power, where alpha phases modulated behaviour (in this case, response time).
  • They conclude that oscillations in multiple frequency ranges, as well as coupling within and across frequencies, may be critical for sequence processing.
