New paper in eLife: Erb et al., Tem­po­ral selec­tiv­i­ty declines in the aging human audi­to­ry cor­tex

Con­grat­u­la­tions to Oble­ser­lab post­doc Julia Erb for her new paper to appear in eLife, “Tem­po­ral selec­tiv­i­ty declines in the aging human audi­to­ry cor­tex”. It’s a trope that old­er lis­ten­ers strug­gle more in com­pre­hend­ing speech (think of Pro­fes­sor Tour­nesol in the…

New paper in press in elife: Waschke et al.

Oble­ser­lab senior PhD stu­dent Leo Waschke, along­side co-authors Sarah Tune and Jonas Obleser, has a new paper in eLife. The pro­cess­ing of sen­so­ry infor­ma­tion from our envi­ron­ment is not con­stant but rather varies with changes in ongo­ing brain activ­i­ty, or…

New paper in press in the Jour­nal of Neu­ro­science

Wöst­mann, Alavash and Obleser demon­strate that alpha oscil­la­tions in the human brain imple­ment dis­trac­tor sup­pres­sion inde­pen­dent of tar­get selec­tion. In the­o­ry, the abil­i­ty to selec­tive­ly focus on rel­e­vant objects in our envi­ron­ment bases on selec­tion of tar­gets and sup­pres­sion of…

New paper in press in the Jour­nal of Cog­ni­tive Neu­ro­science

Wöst­mann, Schmitt and Obleser demon­strate that clos­ing the eyes enhances the atten­tion­al mod­u­la­tion of neur­al alpha pow­er but does not affect behav­iour­al per­for­mance in two lis­ten­ing tasks Does clos­ing the eyes enhance our abil­i­ty to lis­ten atten­tive­ly? In fact, many…

New paper in PNAS by Alavash, Tune, Obleser

How brain areas com­mu­ni­cate shapes human com­mu­ni­ca­tion: The hear­ing regions in your brain form new alliances as you try to lis­ten at the cock­tail par­ty Oble­ser­lab Post­docs Mohsen Alavash and Sarah Tune rock out an intri­cate graph-the­o­ret­i­­cal account of mod­u­lar…

New paper by Erb et al. in Cere­bral Cor­tex: Human but not mon­key audi­to­ry cor­tex is tuned to slow tem­po­ral rates

In a new com­par­a­tive fMRI study just pub­lished in Cere­bral Cor­tex, AC post­doc Julia Erb and her col­lab­o­ra­tors in the Formisano (Maas­tricht Uni­ver­si­ty) and Van­duf­fel labs (KU Leu­ven) pro­vide us with nov­el insights into speech evo­lu­tion. These data by Erb et…

New paper in Neu­roim­age by Fiedler et al.: Track­ing ignored speech mat­ters

Lis­ten­ing requires selec­tive neur­al pro­cess­ing of the incom­ing sound mix­ture, which in humans is borne out by a sur­pris­ing­ly clean rep­re­sen­ta­tion of attend­ed-only speech in audi­to­ry cor­tex. How this neur­al selec­tiv­i­ty is achieved even at neg­a­tive sig­­nal-to-noise ratios (SNR) remains unclear. We show…

New paper in press in the Euro­pean Jour­nal of Neu­ro­science: Wöst­mann et al demon­strate that the pow­er of pres­tim­u­lus alpha oscil­la­tions direct­ly relates to con­fi­dence in pitch-dis­crim­i­na­tion

What is the mech­a­nis­tic rel­e­vance of neur­al alpha oscil­la­tions (~10 Hz) for per­cep­tion? To answer this ques­tion, we analysed EEG data from a task that required par­tic­i­pants to com­pare the pitch of two tones that were, unbe­knownst to par­tic­i­pants, iden­ti­cal. Impor­tant­ly,…
