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.

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.
