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.
