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!

Oble­ser­lab retreat Jan­u­ary 2024

A few weeks ago, we had two sci­en­tif­i­cal­ly very intense days where we retreat­ed to Cor­nelius Borck’s love­ly Uni­ver­si­ty out­post in the pit­toresque city cen­ter of Lübeck (thanks for hav­ing us!) and re-vis­it­ed and re-thought out cur­rent and future research agen­da. Thanks to all cur­rent (and future!) lab mem­bers who con­tributed so thought­ful­ly to this. I enjoyed it immense­ly. After a few years with­out prop­er lab retreats and now the pan­dem­ic behind us, we will cer­tain­ly do more of this lat­er in the year.

New papers in autumn 2023:

Twen­ty-twen­tythree has prob­a­bly not been our most pro­lif­ic year in terms of putting out new research find­ings, which in part is an inter­est­ing delayed con­se­quence of the lab close-down/s­low-down in the pan­dem­ic years. But …

… here we are in autumn 2023 with no less than three fresh find­ings and perspectives:

First, grad­u­ate trainee Frauke Kraus has pub­lished in the Soci­ety for Neu­ro­science out­let eNeu­ro her new find­ings on how moti­va­tion­al state is able to affect lis­ten­ing behav­iour and lis­ten­ing effort (as prox­ied by pupil dilation).

Sec­ond, with our col­leagues from the trans­la­tion­al psy­chi­a­try unit, main­ly Christi­na Andreou and Ste­fan Borg­wardt, Jonas con­tributed to an umbrel­la review on the most like­ly can­di­date pre­dic­tors of an indi­vid­ual at risk tran­si­tion­ing into psy­chosis, in the Jour­nal Trans­la­tion­al Psy­chi­a­try (a spin-off by the mar­ket­ing genius­es at Nature Springer) – the umbrel­la review pos­es a corol­lary of our joint work on hal­lu­ci­na­tions and meta-cog­ni­tion in nor­mal and aber­rant per­cep­tion (stay tuned for more on that one!).

Not least, a new review and a true col­lab­o­ra­tive effort from many neu­ro­science col­leagues here at the Uni­ver­si­ty of Lübeck led by Nico Bun­zeck, we are argu­ing in Neu­ro­science and Biobe­hav­iour­al  Reviews that patho­log­i­cal aging might begin in earnest when and if the typical/healthy func­tion­al com­pen­sa­tion for brain struc­tur­al decline breaks down. Check it out.

We are hir­ing: two new PhD train­ing oppor­tu­ni­ties start­ing ear­ly next year!

© az1172/ Flickr [CC BY-SA 2.0]

Our two senior researchers, Sarah Tune and Malte Wöst­mann, are hap­py to each announce the open­ing of a three-year PhD posi­tion in the Obleser lab. The posi­tions are part of two recent­ly fund­ed DFG grants, and will fea­ture real­ly excit­ing com­bi­na­tions of behav­iour mod­el­ling and neur­al dynamics!

Sarah’s project will look into how per­cep­tu­al infer­ence changes with age, using speech per­cep­tion as a mod­el sys­tem. It will bring togeth­er behav­iour­al speech per­cep­tion exper­i­ments and func­tion­al neu­roimag­ing, and apply com­pu­ta­tion­al mod­el­ling to link between the two.

For full details, see the offi­cial job ad.

Malte’s project will focus on audi­to­ry atten­tion and its neur­al bases. It will com­bine behav­iour­al and elec­troen­cephalog­ra­phy (EEG) data in younger and old­er adults to inves­ti­gate the neu­ro-cog­ni­tive mech­a­nisms under­ly­ing cap­ture of atten­tion and sup­pres­sion of distraction.

For full details, see the offi­cial job ad.

The appli­ca­tion dead­line (as sin­gle PDF to the email address named in the ad!) is Nov 19, 2023!

Please don’t hes­i­tate to con­tact Sarah or Malte if you have any infor­mal ques­tions about PhD posi­tions and projects. Sarah will also be at APAN and SfN soon, if you feel like chat­ting with her about the position.

We are look­ing for­ward to many inter­est­ing applications!

A grant dou­ble to celebrate

We are hon­oured and delight­ed that the Deutsche Forschungs­ge­mein­schaft has deemed two of our recent appli­ca­tions wor­thy of fund­ing: The two senior researchers in the  lab, Sarah Tune and Malte Wöst­mann, have both been award­ed three-year grant fund­ing for their new projects. Congratulations!

In her 3‑year, 360‑K€ project “How per­cep­tu­al infer­ence changes with age: Behav­iour­al and brain dynam­ics of speech per­cep­tion”, Sarah Tune will explore the role of per­cep­tu­al pri­ors in speech per­cep­tion in the age­ing lis­ten­er. She will main­ly use neur­al and per­cep­tu­al mod­el­ling and func­tion­al neuroimaging.

In his 3‑year, 270‑K€ project “Inves­ti­ga­tion of cap­ture and sup­pres­sion in audi­to­ry atten­tion”, Malte Wöst­mann will con­tin­ue and refine his suc­cess­ful research endeav­our into dis­so­ci­at­ing the role of sup­pres­sive mech­a­nisms in the lis­ten­ing mind and brain, main­ly using EEG and behav­iour­al modelling.

Both of them will soon adver­tise posts for PhD can­di­dates to join us, accord­ing­ly, and to work on these excit­ing projects with Sarah and Malte and the rest of the Oble­ser­lab team

The “Hörhanse” [hanseat­ic hear­ing] has begun!

We are delight­ed to be a found­ing mem­ber of the Hörhanse, a Lübeck con­sor­tium of all play­ers research­ing, teach­ing, sell­ing, or treat­ing hear­ing.
Hear­ing acoustics is a focal point at the Hanse Inno­va­tion Cam­pus Lübeck. Unique in Ger­many is the large num­ber of insti­tu­tions that work togeth­er with renowned play­ers to advance the top­ic of hear­ing around the cam­pus: Hear­ing, acoustics and com­mu­ni­ca­tion are advanced in their most diverse facets in research projects, study pro­grammes, the nation­wide train­ing of hear­ing care pro­fes­sion­als, in the clin­i­cal area and through inter­dis­ci­pli­nary coop­er­a­tion.

The found­ing project part­ners of HörHanse are the three uni­ver­si­ties in Lübeck: our host insti­tu­tion Uni­ver­si­ty of Lübeck, plus the Lübeck Uni­ver­si­ty of Tech­nol­o­gy, Musikhochschule Lübeck (MHL), as well as the Uni­ver­si­ty Hos­pi­tal Schleswig-Hol­stein, the Ger­man Hear­ing Aid Insti­tute (DHI), the Fed­er­al Guild of Hear­ing Aid Acousti­cians (biha), the Acad­e­my of Hear­ing Aid Acoustics, the State Voca­tion­al School for Hear­ing Aid Acousti­cians, and the com­pa­ny hear con­cept.

New research fund­ing: joint project with WSA

I am hap­py and hon­oured that one of the lead­ing hear­ing aid devel­op­ers and man­u­fac­tur­ers, Widex Sivan­tos Audi­ol­o­gy (WSA), has agreed with Uni­ver­si­ty of Lübeck to fund 3 more excit­ing years of research at the Obleser lab! We will be joint­ly look­ing at the intri­ca­cies of how age­ing lis­ten­ers nav­i­gate a noisy world and its com­mu­ni­ca­tion challenges.

New Review paper on Cir­ca­di­an Rhythms in Audi­to­ry Hal­lu­ci­na­tions and Psy­chosis to come out in “Acta Physiologica”

As part of our increased efforts to under­stand the impact of chrono­bi­ol­o­gy in sen­sa­tion and per­cep­tion, a new review arti­cle by senior researcher Hong-Viet Ngo in the lab and Jonas Obleser, togeth­er with psy­chi­a­trist Christi­na Andreou and chrononeu­ro­phys­i­ol­o­gist Hen­rik Oster is forthcoming!

The paper sum­maris­es our (sketchy) knowl­edge on how cir­ca­di­an rhythms impact audi­to­ry hal­lu­ci­na­tion propen­si­ty, and how key neur­al sig­na­tures E:I (dys-)balance and dopamin­er­gic sig­nalling joint­ly might con­tribute to hal­lu­ci­na­tions as a key symp­tom in  psy­chosis. The paper has been accept­ed in the clas­sic jour­nal Acta Phys­i­o­log­i­ca. A preprint ver­sion is avail­able here.
