New paper in press: Hen­ry, Her­rmann, & Obleser in PNAS

Con­grat­u­la­tions to Audi­to­ry Cognition’s very own Mol­ly Hen­ry who, with Björn Her­rmann and Jonas Obleser, is about to pub­lish yet anoth­er PNAS paper:

Entrained neur­al oscil­la­tions in mul­ti­ple fre­quen­cy bands co-mod­u­late behavior

Hen­ry MJ, Her­rmann B, & Obleser J. PNAS, in press.

We are very excit­ed about this one, as it harks back to Molly’s 2012 PNAS paper yet ups the ante some­what: How do neur­al oscil­la­tions behave towards a more real­is­ti­cal­ly com­plex mix­ture of acoustic reg­u­lar­i­ties, and how does lis­ten­ing behav­iour change as a func­tion of var­i­ous neur­al entrained phases?

Our sen­so­ry envi­ron­ment is teem­ing with com­plex rhyth­mic struc­ture, but how do envi­ron­men­tal rhythms (like those present in speech or music) affect our per­cep­tion? In a human elec­troen­cephalog­ra­phy study, we inves­ti­gat­ed how audi­to­ry per­cep­tion is affect­ed when brain rhythms (neur­al oscil­la­tions) syn­chro­nize with the com­plex rhyth­mic struc­ture in syn­thet­ic sounds that pos­sessed rhyth­mic char­ac­ter­is­tics sim­i­lar to speech. We found that neur­al phase in mul­ti­ple fre­quen­cy bands syn­chro­nized to the com­plex stim­u­lus rhythm and inter­act­ed to deter­mine tar­get-detec­tion per­for­mance. Crit­i­cal­ly, the influ­ence of neur­al oscil­la­tions on tar­get-detec­tion per­for­mance was present only for fre­quen­cy bands syn­chro­nized with the rhyth­mic struc­ture of the stim­uli. Our results elu­ci­date how mul­ti­ple fre­quen­cy bands shape the effec­tive neur­al pro­cess­ing of envi­ron­men­tal stimuli.

Stay tuned until after PNAS embar­go has been lifted!
