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!

New paper by Mol­ly Hen­ry: Amu­sia diag­no­sis should bet­ter rely on sig­nal detec­tion theory

Sig­nal detec­tion the­o­ry – what helps pre­vent­ing mis­di­ag­noses and false pos­i­tives in gen­er­al can’t be bad for diag­nos­ing Amu­sia either, one would think. Our very own Mol­ly Hen­ry and her for­mer super­vi­sor Devin McAuley now demon­strate in a just-accept­ed paper

Fail­ure to apply sig­nal detec­tion the­o­ry to the Mon­tre­al Bat­tery of Eval­u­a­tion of Amu­sia may mis­di­ag­nose amusia

in Music Per­cep­tion that this is indeed the case:

They show that analy­ses based on con­fi­dence rat­ings and ROC-curves out­per­forms sim­ple per­cent­age cor­rect in diag­nos­ing Amusia.

Here is the abstract, and watch out for the full paper to appear soon:

This arti­cle con­sid­ers a sig­nal detec­tion the­o­ry (SDT) approach to eval­u­a­tion of per­for­mance on the Mon­tre­al Bat­tery of Eval­u­a­tion of Amu­sia (MBEA).

New paper in press — Scharinger et al., PLOS ONE [Update]

We are hap­py that our paper

A Sparse Neur­al Code for Some Speech Sounds but Not for Others

is sched­uled for pub­li­ca­tion in PLOS ONE on July 16th, 2012.

This is also our first paper in col­lab­o­ra­tion with Alexan­dra Ben­dix­en from the Uni­ver­si­ty of Leipzig.

The research report­ed in this arti­cle pro­vides an exten­sion of the pre­dic­tive cod­ing frame­work onto speech sounds and assumes that audi­to­ry pro­cess­ing uses pre­dic­tions that are not only derived from ongo­ing con­tex­tu­al updates, but also from long-term mem­o­ry rep­re­sen­ta­tions — neur­al codes — of speech sounds. Using the Ger­man min­i­mal pair [lats]/[laks] (bib/salmon) in a pas­sive-odd­ball design, we find the expect­ed Mis­match Neg­a­tiv­i­ty (MMN) asym­me­try that is com­pat­i­ble with a pre­dic­tive cod­ing frame­work, but also with lin­guis­tic under­spec­i­fi­ca­tion theory.
