  AC post­doc Malte Wöst­mann scores DFG grant to study the tem­po­ral dynam­ics of the audi­to­ry atten­tion­al filter

  In this three-year project, we will use the audi­to­ry modal­i­ty as a test case to inves­ti­gate how the sup­pres­sion of dis­tract­ing infor­ma­tion (i.e., “fil­ter­ing”) is neu­ral­ly imple­ment­ed. While it is known that the atten­tion­al sam­pling of tar­gets (a) is rhyth­mic, (b) can be entrained, and © is mod­u­lat­ed by top-down pre­dic­tions, the exis­tence and neur­al imple­men­ta­tion 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 of us tend to close their eyes when lis­ten­ing con­di­tions become chal­leng­ing, for exam­ple on the […]

  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 recon­fig­u­ra­tions in chal­leng­ing lis­ten­ing sit­u­a­tions, and how these pre­dict indi­vid­u­als’ lis­ten­ing success. Avail­able online now in […]

  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 al. reveal homolo­gies and dif­fer­ences in nat­ur­al sound-encod­ing in human and non-human pri­mate cortex. From […]

  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 that, under such con­di­tions, a late cor­ti­cal rep­re­sen­ta­tion (i.e., neur­al track­ing) of the ignored acoustic sig­nal […]

  New paper in The Jour­nal of Neu­ro­science: Wilsch et al.., Tem­po­ral expec­ta­tion mod­u­lates the cor­ti­cal dynam­ics of short-term memory

  Con­grat­u­la­tions to Oble­ser­lab alum­na Anna Wilsch, who is – for now – leav­ing acad­e­mia on a true high with her lat­est offer­ing on how tem­po­ral expec­ta­tions (“fore­knowl­edge” about when some­thing is to hap­pen) shape the neur­al make-up of memory! Record­ed while the Oble­ser­lab was still in Leipzig at the Max Planck, and analysed with great […]

  New paper in Ear and Hear­ing: Erb, Lud­wig, Kunke, Fuchs & Obleser on speech com­pre­hen­sion with a cochlear implant

  We are excit­ed to share the results from our col­lab­o­ra­tion with the Cochlea Implant Cen­ter Leipzig: AC post­doc Julia Erb’s new paper on how 4‑Hz mod­u­la­tion sen­si­tiv­i­ty can inform us on 6‑month speech com­pre­hen­sion out­come in cochlear implants. Erb J, Lud­wig AA, Kunke D, Fuchs M, & Obleser J (2018). Tem­po­ral sen­si­tiv­i­ty mea­sured short­ly after […]

  New paper in press in Brain Stim­u­la­tion: Wöst­mann, Vosskuhl, Obleser, and Her­rmann demon­strate that exter­nal­ly ampli­fied oscil­la­tions affect audi­to­ry spa­tial attention

  In a fine col­lab­o­ra­tion we com­bine exper­tise on audi­to­ry cog­ni­tion (Malte Wöst­mann & Jonas Obleser, Uni­ver­si­ty of Lübeck) and brain stim­u­la­tion (Johannes Vosskuhl and Christoph S Her­rmann, Uni­ver­si­ty of Old­en­burg) to show that exter­nal­ly stim­u­lat­ed alpha and gam­ma oscil­la­tions dif­fer­en­tial­ly affect spa­tial atten­tion to speech. Our par­tic­i­pants per­formed a dichot­ic lis­ten­ing task while being stim­u­lat­ed […]
