New paper out: Erb, Hen­ry, Eis­ner & Obleser — Jour­nal of Neuroscience

We are proud to announce that PhD stu­dent Julia Erb just came out with a paper issued in Jour­nal  of Neu­ro­science:

The Brain Dynam­ics of Rapid Per­cep­tu­al Adap­ta­tion to Adverse Lis­ten­ing Conditions

Effects of adaptation

Abstract:

Lis­ten­ers show a remark­able abil­i­ty to quick­ly adjust to degrad­ed speech input. Here, we aimed to iden­ti­fy the neur­al mech­a­nisms of such short-term per­cep­tu­al adap­ta­tion. In a sparse-sam­pling, car­diac-gat­ed func­tion­al mag­net­ic res­o­nance imag­ing (fMRI) acqui­si­tion, human lis­ten­ers heard and repeat­ed back 4‑band-vocod­ed sentences

New paper out: Hen­ry & Her­rmann, Jour­nal of Neuroscience

Proud to announce that our post­docs Mol­ly Hen­ry and Björn Her­rmann just came out with a review/op piece in the Jour­nal of Neu­ro­science “jour­nal club” sec­tion, where only grad stu­dents or post­docs are allowed to author short review pieces.

A Pre­clud­ing Role of Low-Fre­quen­cy Oscil­la­tions for Audi­to­ry Per­cep­tion in a Con­tin­u­ous Pro­cess­ing Mode

The Jour­nal of Neu­ro­science, 5 Decem­ber 2012, 32(49): 17525–17527; doi: 10.1523/​JNEUROSCI.4456–12.2012

Mol­ly and Björn review (and com­ment on) an impor­tant paper by our friends and col­leagues Christoph Kayser and Benedikt Ng in the same jour­nal. Essen­tial­ly, they argue for the dis­tinc­tion of a con­tin­u­ous from an oscil­la­to­ry pro­cess­ing mode in lis­ten­ing, and pro­vide ten­ta­tive expla­na­tions of why some­times miss­es might be more mod­u­lat­ed by neur­al oscil­la­to­ry phase than hits. Con­grats, guys!

Adverse Lis­ten­ing Con­di­tions and Mem­o­ry Load Dri­ve a Com­mon Alpha Oscil­la­to­ry Network

Whether we are engaged in small talk or try­ing to mem­o­rise a tele­phone num­ber — it is our short-term mem­o­ry that ensures we don’t lose track. But what if the very same mem­o­ry gets addi­tion­al­ly taxed because the words to be remem­bered are hard to understand?

Talk at the Soci­ety for Neu­ro­science Meet­ing, Wash­ing­ton, DC on Wednesday

If you hap­pen to be at SfN this week, you might want to check out my short pre­sen­ta­tion on a recent study [1] we did: What do spec­tral (fre­quen­cy-domain) and tem­po­ral (time-domain) fea­tures real­ly con­tribute to speech com­pre­hen­sion process­es in the tem­po­ral lobes?

It is in the Audi­to­ry Cor­tex Ses­sion (710), tak­ing place in Room 145B. My talk is sched­uled for 0945 am.
