New paper with the Weisz lab in eLife: Aber­rant per­cep­tu­al pre­dic­tions in Tinnitus

Now out in eLife, Lisa Reisinger and Nathan Weisz (Salzburg) with a diverse team includ­ing myself (J.O.) show, using state of the art decod­ing mod­els and a rig­or­ous  approach of inter­nal, pre-reg­is­tered repli­ca­tion, that peo­ple liv­ing with tin­ni­tus (a chron­ic and often very dis­tress­ing audi­to­ry “phan­tom per­cept”) show altered pat­terns of pre­dic­tive audi­to­ry pro­cess­ing. Check it out!

The eLife edi­to­r­i­al assess­ment reads like this: “This impor­tant work presents two stud­ies on pre­dic­tive process­es in sub­jects with and with­out tin­ni­tus. The evi­dence sup­port­ing the authors’ claims is com­pelling, as their sec­ond study serves as an inde­pen­dent repli­ca­tion of the first. Rig­or­ous match­ing between study groups was per­formed, espe­cial­ly in the sec­ond study, increas­ing the prob­a­bil­i­ty that the iden­ti­fied dif­fer­ences in pre­dic­tive pro­cess­ing can tru­ly be attrib­uted to the pres­ence of tin­ni­tus. This work will be of inter­est to researchers, espe­cial­ly neu­ro­sci­en­tists, in the tin­ni­tus field.”

Jonas elect­ed and appoint­ed as DFG review panelist

Jonas Obleser has been elect­ed by the Ger­man sci­en­tif­ic com­mu­ni­ty as one of the new mem­bers of the so-called “Fachkol­legium” (a select, stand­ing group of review pan­elists) of the Ger­man Research Foun­da­tion (DFG) in the field of sys­temic and cog­ni­tive neu­ro­science.

This is an hon­ourable, non-prof­it addi­tion­al task that pri­mar­i­ly involves sug­gest­ing fund­ings deci­sions for grant pro­pos­als in the field of neu­ro­science. Here’s to four excit­ing if work-intense years.

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.

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

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.

Hot off the press: New chap­ter on neur­al oscil­la­tions in speech per­cep­tion by Tune & Obleser

Neur­al oscil­la­tions are a promi­nent fea­ture of the brain’s elec­tro­phys­i­ol­o­gy and tar­get vari­ables in many speech per­cep­tion stud­ies. For the lat­est edi­tion of the Springer Hand­book Audi­to­ry Research – this time focused on speech per­cep­tion – lab mem­bers Sarah Tune and Jonas Obleser teamed up to take stock of what has been learned about the func­tion­al rela­tion­ship of neur­al oscil­la­tions and speech perception.

By focus­ing on core func­tions and com­pu­ta­tion­al prin­ci­ples, the chap­ter offers a par­si­mo­nious account of the sta­ble pat­terns that have emerged across stud­ies and lev­els of investigations.

You can find a preprint of the chap­ter here and the entire col­lec­tion of chap­ters here.
