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 paper in Sci­ence Advances by Schmitt et al.

Very excit­ed to announce that for­mer Obleser lab PhD stu­dent Lea-Maria Schmitt with her co-authors *) is now out in the Jour­nal Sci­ence Advances with her new work, fus­ing artif­i­cal neur­al net­works and func­tion­al MRI data, on timescales of pre­dic­tion in nat­ur­al lan­guage comprehension:

“Pre­dict­ing speech from a cor­ti­cal hier­ar­chy of event-based time scales”

*) Lea-Maria Schmitt, Julia Erb, Sarah Tune, and Jonas Obleser from the Obleser lab / Lübeck side, and our col­lab­o­ra­tors Anna Rysop and Gesa Hartwigsen from Gesa’s Lise Meit­ner group at the Max Planck Insti­tute in Leipzig. This research was made pos­si­ble by the ERC and the DFG.

New project with Gesa Hartwigsen (Max Planck Leipzig): What is Angu­lar Gyrus actu­al­ly up to?

San­ta struck ear­ly this year: The Deutsche Forschungs­ge­mein­schaft (DFG) has just grant­ed AC head Jonas (Uni­ver­si­ty of Lübeck) and brain-stim­u­la­tion wiz Gesa Hartwigsen (now a group leader at AC’s for­mer insti­tu­tion, the MPI in Leipzig) a joint 3‑year grant, worth 371,000 € in total, on “Mod­u­lat­ing neur­al net­work dynam­ics of speech com­pre­hen­sion: The role of the angu­lar gyrus”. This project will build on Gesa and Jonas’ recent paper in Cor­tex on the top­ic. Thanks again to the fund­ing body and the help­ful reviewers!

New paper out: Tune & Asari­dou, Jour­nal of Neuroscience

Our newest mem­ber of the lab, post-­doc Sarah Tune, just pub­lished a review arti­cle in the Jour­nal of Neu­ro­science. The arti­cle appeared in the “Jour­nal Club” sec­tion, where grad­u­ate stu­dents or post-docs are giv­en the chance to write short review pieces.

Now avail­able online:
Stim­u­lat­ing the Seman­tic Net­work: What Can TMS Tell Us about the Roles of the Pos­te­ri­or Mid­dle Tem­po­ral Gyrus and Angu­lar Gyrus?

Sarah and for­mer UCI Brain Cir­cuits col­league Salo­mi Asari­dou com­ment on a recent TMS study by Dav­ey et al. (2015) who inves­ti­gat­ed the role(s) of the mid­dle tem­po­ral gyrus and angu­lar gyrus in the encod­ing and retrieval of seman­tic infor­ma­tion. Sarah and Salo­mi review and dis­cuss some of the fac­tors that lim­it the inter­pre­ta­tion of rTMS-induced behav­ioral changes in seman­tic judge­ment tasks. Con­clud­ing, they argue that a focus on neur­al net­works and mech­a­nis­tic prin­ci­ples is key to under­stand­ing the neur­al imple­men­ta­tion of seman­tic cognition.
