Towards a brain-controlled hearing aid: PhD student Lorenz Fiedler shows how attended and ignored auditory streams are differently represented in the neural responses and how the focus of auditory attention can be extracted from EEG signals recorded at electrodes placed inside the ear-canal and around the ear.
Auditory Cognition’s own Malte Wöstmann is in press in Cerebral Cortex with his latest offering on how attentional control manifests in alpha power changes: Ignoring speech can be beneficial (if comprehending speech potentially detracts from another task), and we here show how this change in listening goals turns around the pattern of alpha-power changes with changing speech degradation. (We will update as the paper becomes available online.)

A review article for those interested in how to use magneto-/electroencephalography (M/EEG) to study speech comprehension. We provide a historically informed overview over dependent measures in the time and frequency domain, highlight recent advances resulting from these measures and review the notorious challenges and solutions speech and language researchers are faced with when studying electrophysiological brain responses.
Now available online:
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.

Based on Malte’s recent J Neurosci study, Jonas did a brief interview for German radio detektor.fm today and talked listening effort, digital phone lines, noise reduction, and next-generation hearing aids with host Teresa Nehm. (In German only.)
I had the honour of guest-editing a special issue for the classic journal “Brain and Language” and have thus contributed a brief editorial (now online) to this issue. The special issue re-visits old themes and new leads in the electrophysiology of speech, language, and its precursors.
UPDATE: The full special issue appeared in September 2015 and all articles are now accessible and citable. Thanks for your kind attention!
In a collaboration with the University Clinic of Leipzig and Prof Dr Gesa Hartwigsen (now University of Kiel), a new paper is to appear in “Cortex”, in the forthcoming special issue on Prediction in Speech and Language, edited by Alessandro Tavano and AC alumnus Mathias Scharinger.

Julia Erb just got accepted the third study of her PhD project,
It will appear in Frontiers in Systems Neuroscience soon.
The data are an extension (in older adults) of Julia’s Journal of Neuroscience paper earlier this year.
