New paper in press: Her­rmann, Schlicht­ing, & Obleser, Jour­nal of Neuroscience

Björn Her­rmann has yet anoth­er paper in press in the Jour­nal of Neuroscience!

Dynam­ic Range Adap­ta­tion to Spec­tral Stim­u­lus Sta­tis­tics in Human Audi­to­ry Cortex

The paper is now avail­able online free of charge, and—funnily enough—appeared right on Jan­u­ary 1, 2014.

SNAP sum­ma­ry and impressions

The SNAP work­shop (Sig­nal and Noise along the Audi­to­ry Path­way) is behind us.

It is safe to say that it has been a great suc­cess. We will care­ful­ly look into the eval­u­a­tion forms you pro­vid­ed, and we will inform here in due course whether and when a 2nd SNAP (poten­tial­ly 2015) is in the making.

Let us thank all of you who made SNAP hap­pen. It turned a fun and suc­cess­ful sci­en­tif­ic year 2013 into an even greater one. Thank you! We hope to see you soon again, somewhere.

Now, here are some impres­sions of SNAP 2013:

P.S. Here you find Jonas’ clos­ing sum­ma­ry notes:

New paper in press: Erb & Obleser, Fron­tiers in Sys­tems Neuroscience

Julia Erb just got accept­ed the third study of her PhD project,

Upreg­u­la­tion of cog­ni­tive con­trol net­works in old­er adults’ speech comprehension

It will appear in Fron­tiers in Sys­tems Neu­ro­science soon.

The data are an exten­sion (in old­er adults) of Julia’s Jour­nal of Neu­ro­science paper ear­li­er this year.

New paper in press: Hen­ry & Obleser, PLOS ONE [Update]

Watch this space and the PLOS ONE web­site for a forth­com­ing arti­cle by Mol­ly Hen­ry and me;

Dis­so­cia­ble neur­al response sig­na­tures for slow ampli­tude and fre­quen­cy mod­u­la­tion in human audi­to­ry cortex

Hark­ing back at what we had argued ini­tial­ly in our 2012 Fron­tiers op’ed piece (togeth­er with Björn Her­rmann), Mol­ly presents neat evi­dence for dis­so­cia­ble cor­ti­cal sig­na­tures of slow ampli­tude ver­sus fre­quen­cy mod­u­la­tion. These cor­ti­cal sig­na­tures poten­tial­ly pro­vide an effi­cient means to dis­sect simul­ta­ne­ous­ly com­mu­ni­cat­ed slow tem­po­ral and spec­tral infor­ma­tion in acoustic com­mu­ni­ca­tion signals.

Lis­ten­ing: The strat­e­gy mat­ters [Update]

In press on Neuropsychologia

Thal­a­m­ic and pari­etal brain mor­phol­o­gy pre­dicts audi­to­ry cat­e­go­ry learning

figure_mat

Cat­e­go­riz­ing sounds is vital for adap­tive human behav­ior. Accord­ing­ly, chang­ing lis­ten­ing sit­u­a­tions (exter­nal noise, but also periph­er­al hear­ing loss in aging) require lis­ten­ers to flex­i­bly adjust their cat­e­go­riza­tion strate­gies, e.g., switch amongst avail­able acoustic cues. How­ev­er, lis­ten­ers dif­fer con­sid­er­ably in these adap­tive capa­bil­i­ties. For this rea­son, we employed vox­el-based mor­phom­e­try (VBM) in our study (Neu­ropsy­cholo­gia, In press), in order to assess the degree to which indi­vid­ual brain mor­phol­o­gy is pre­dic­tive of such adap­tive lis­ten­ing behavior.

New paper in press: Her­rmann, Hen­ry, Grigutsch & Obleser, The Jour­nal of Neu­ro­science [Update]

Oscil­la­to­ry Phase Dynam­ics in Neur­al Entrain­ment Under­pin Illu­so­ry Per­cepts of Time

Nat­ur­al sounds like speech and music inher­ent­ly vary in tem­po over time. Yet, con­tex­tu­al fac­tors such as vari­a­tions in the sound’s loud­ness or pitch influ­ence per­cep­tion of tem­po­ral rate change towards slow­ing down or speed­ing up.

A new MEG study by Björn Her­rmann, Mol­ly Hen­ry, Maren Grigutsch and Jonas Obleser asked for the neur­al oscil­la­to­ry dynam­ics that under­pin con­text-induced illu­sions in tem­po­ral rate change and found illu­so­ry per­cepts to be linked to changes in the neur­al phase pat­terns of entrained oscil­la­tions while the exact fre­quen­cy of the oscil­la­to­ry response was relat­ed to veridi­cal percepts.

The paper is in press and forth­com­ing in The Jour­nal of Neuroscience.

Paper is avail­able online.
