AC postdocs Sarah Tune and Malte Wöstmann have a new paper out online in the special issue on Neural Oscillations in the European Journal of Neuroscience! We are excited to share the results from our first study of the ERC-funded project on listening behavior and adaptive control in middle-aged adults. In this study, we asked whether the fidelity of alpha power lateralization would serve as a neural marker of selective auditory attention in the ageing listener. The results of our multivariate approach demonstrate that understanding inter-individual differences is paramount to understanding of the role of alpha oscillations in auditory attention across age.

Obleserlab postdoc Mohsen Alavash and Obleserlab Alumna Sung-Joo Lim are in press at Neuroimage!
They argue with data from a placebo-controlled dopaminergic intervention study that BOLD signal variability and the functional connectome are surprisingly clearly affected by L-Dopa, and (ii) that the degree of change in these metrics can explain the degree to which individuals will profit from L-DOPA in performing the challenging listening task (while others dont; Preprint here ).

— Thanks also and in particular to our colleagues Christiane Thiel of Oldenburg, and Bernhard Sehm and Lorenz Deserno of Leipzig, who helped us made this large-scale L-DOPA project happen!
AC alumna Anna Wilsch has a new paper in press in Neuroimage, with Toralf Neuling, Jonas Obleser, and Christoph Herrmann: “Transcranial alternating current stimulation with speech envelopes modulates speech comprehension”. In this proof-of-concept–like paper, we demonstrate that using the speech envelope as a “pilot signal” for electrically stimulating the human brain, while a listener tries to comprehend that speech signal buried in noise, does modulate the listener’s speech–in–noise comprehension abilities.
SNAP 2017 took place on December 8 and 9 in Lübeck, Germany.
Nine internationally esteemed speakers and in total more than sixty researchers from all over Europe, Canada and the US made the second Signal and Noise Along the Auditory Pathway workshop a memorable occasion in auditory neuroscience.
Thanks to everybody for coming out!, and see you all again for SNAP 2019, at a location to be announced.
