For those interested in auditory cortex and how a regime of predictions, prediction updates and surprise (a version of “prediction error”) might be implemented there, I contributed a brief featurette (“insight”, they call it) to eLife on a recent paper by Will Sedley, Tim Griffiths, and others. Check it out.

Wöstmann, Herrmann, Maess and Obleser demonstrate that the hemispheric lateralization of neural alpha oscillations measured in the magnetoencephalogram (MEG) synchronizes with the speech signal and predicts listeners’ speech comprehension.

Press release:
And again, AC-Alumni Björn Herrmann got a new paper in press / online at NeuroImage on
Cheers.

Congratulation to PhD student Malte Wöstmann, who – with Erich Schröger and Jonas Obleser – has a new article in press at the Journal of Cognitive Neuroscience
Acoustic detail guides attention allocation in a selective listening task
forthcoming. We will update you accordingly as the paper comes online. We will share however one of Malte’s figures here as a teaser: The paper utilises a very classic component of the evoked potential, the contingent negative variation (the CNV; or a close relative thereof, see the actual paper for discussion) to study how older and younger listeners allocate their attentional resources depending on implicit cues on to-be-expected listening difficulties.

Congratulations to Auditory Cognition’s very own Molly Henry who, with Björn Herrmann and Jonas Obleser, is about to publish yet another PNAS paper:
Entrained neural oscillations in multiple frequency bands co-modulate behavior
Henry MJ, Herrmann B, & Obleser J. PNAS, in press.
We are very excited about this one, as it harks back to Molly’s 2012 PNAS paper yet ups the ante somewhat: How do neural oscillations behave towards a more realistically complex mixture of acoustic regularities, and how does listening behaviour change as a function of various neural entrained phases?
Stay tuned until after PNAS embargo has been lifted!
[UPDATE]PNAS paper is online. Check it out here.

It’s only a week ago that we updated you about Antje’s latest publication at NeuroImage. Today, there is a another one coming in; Antje’s, Malte’s & Jonas’ perspective article on cortical alpha oscillations is in press at frontiers in HUMAN NEUROSCIENCE.
