New paper in eLife: Brain and behav­iour go sep­a­rate ways in the age­ing listener

Out now in eLife: Oble­ser­lab stats mod­el­ling wiz Sarah Tune togeth­er with Jonas has just pub­lished a seri­ous sta­tis­ti­cal piece of evi­dence on how, in our >N=100 cohort of age­ing lis­ten­ers as fund­ed by the Euro­pean Research Coun­cil, neur­al sig­na­tures of atten­tive lis­ten­ing and the actu­al behav­iour­al out­come a lis­ten­er achieves are not triv­ial­ly con­nect­ed, and in fact are not even pre­dic­tive of one anoth­er  – when we look at the lon­gi­tu­di­nal, two-year tra­jec­to­ry that lis­ten­ers exhib­it in both mea­sures over time.

This study (here is a brief eLife digest on it) pos­es a key­stone result to the ERC project “AUDADAPT”, which we now con­tin­ue with oth­er projects and spin-offs. Many thanks to the large group of Lübeck cit­i­zens who con­tin­ue to sup­port us with their pre­cious time and their brain and behav­iour­al data!

Diese Studie (hier ist eine kurze eLife-Zusam­men­fas­sung) ist ein Schlüs­sel­ergeb­nis des ERC-Pro­jek­ts “AUDADAPT”, das wir nun mit anderen Pro­jek­ten und Spin-offs fort­set­zen. Vie­len Dank an die große Gruppe von Lübeck­er Bürg­erin­nen und Bürg­ern, die uns weit­er­hin mit ihrer kost­baren Zeit und ihren Gehirn- und Ver­hal­tens­dat­en unterstützen!

New paper in Devel­op­men­tal Cog­ni­tive Neu­ro­science, Jessen et al.

Our lab (senior author Sarah Tune) teamed up once again with the Baby­lab Lübeck, led by Sarah Jessen: Sarah and Sarah co-wrote a great tuto­r­i­al on how the ver­sa­tile analy­sis frame­work of tem­po­ral response func­tions can be used to analyse brain data obtained in infants. The arti­cle has now been accept­ed for pub­li­ca­tion in the well-reput­ed jour­nal Devel­op­men­tal Cog­ni­tive Neu­ro­science:

New paper in Nature Com­mu­ni­ca­tions by Tune et al.

We are very excit­ed to share that Oble­ser­lab post­doc Sarah Tune has a new paper in Nature Com­mu­ni­ca­tions. „Neur­al atten­tion­al-fil­ter mech­a­nisms of lis­ten­ing suc­cess in mid­dle-aged and old­er par­tic­i­pants“ is our lat­est and to-date most exten­sive out­put of the lon­gi­tu­di­nal ERC Con­sol­ida­tor project on adap­tive lis­ten­ing in age­ing indi­vid­ual (AUDADAPT).

This co-pro­duc­tion with cur­rent (Mohsen Alavash and Jonas Obleser) and for­mer (Lorenz Fiedler) Oble­ser­lab mem­bers, takes an in-depth and inte­gra­tive look at how two of the most exten­sive­ly stud­ied neu­ro­bi­o­log­i­cal atten­tion­al-fil­ter imple­men­ta­tions, alpha pow­er lat­er­al­iza­tion and selec­tive neur­al speech track­ing, relate to one anoth­er and to lis­ten­ing sucess.

Lever­ag­ing our large, rep­re­sen­ta­tive sam­ple of aging lis­ten­ers (N=155, 39–80 years), we show that both neur­al fil­ter imple­men­tatins are robust­ly mod­u­lat­ed by atten­tion but oper­ate sur­prins­ing­ly inde­pen­dent of one another.

In a series of sophis­ti­cat­ed sin­gle-tri­al lin­ear mod­els that include vari­a­tion in neur­al fil­ter strength with­in and between indi­vid­u­als, we demon­strate how the pref­er­en­tial neur­al track­ing of attend­ed ver­sus ignored speech but not alpha lat­er­al­iza­tion boosts lis­ten­ing success.
