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!

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

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 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.

New paper in eLife, Waschke et al.

For­mer Oble­ser­lab PhD stu­dent Leo Waschke is now out in eLife with an inge­nious demon­stra­tion how both endoge­nous and exoge­nous­ly-dri­ven changes in the steep­ness of the brain-elec­tric 1/f pow­er spec­trum (in part linked direct­ly to local excitation:inhibiton, E:I, ratio) in neur­al pop­u­la­tions can affect behav­iour in com­plex, mul­ti-sen­so­ry envi­ron­ments: “Modal­i­ty-spe­cif­ic track­ing of atten­tion and sen­so­ry sta­tis­tics in the human elec­tro­phys­i­o­log­i­cal spec­tral expo­nent”

The results draw heav­i­ly on the recent spec­tral-slope expo­nent work by our col­lab­o­ra­tors at Uni­ver­si­ty of Cal­i­for­nia San Diego in the lab of Bradley Voytek, and have come togeth­er in a three-lab col­labo of Lübeck, San Diego, and Leo’s cur­rent sci­en­tif­ic home, the Dou­glas Gar­rett lab at the MPIB.

 
Con­grat­u­la­tions, Leo!

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:
