New Pub­lic Sci­ence Weblog by our Max Planck Institute

I am per­son­al­ly not entire­ly con­vinced whether Weblogs will sur­vive as a tool for com­mu­ni­ca­tion. Notwith­stand­ing, I am sup­port­ing the idea of our Insti­tute togeth­er with Ger­man pub­lic sci­ence mag­a­zine “Spek­trum der Wis­senschaft” to start a new blog, enti­tled “Neu­rocog­ni­tion”. It’s host­ed at scilogs.eu and scilogs.de. I have the hon­our to serve as one of the staff writ­ers there, let’s see where this will take us.

For a start, I let go and wrote about my fas­ci­na­tion with brain oscil­la­tions. Please pre­tend at least to be sur­prised on this choice of topic!

Fur­ther posters at SFN / Neu­ro­science 2011

In addi­tion to the excit­ing con­so­nan­tal mis­match neg­a­tiv­i­ty work Math­ias and Alexan­dra will be show­ing (TUESDAY AM ses­sion, posters UU10 and UU11), we will have the fol­low­ing posters this year. Come by!

Chris Petkov and I are show­ing our brand new data in the TUESDAY PM ses­sion, poster LL14.

I myself will be pre­sent­ing in the WEDNESDAY AM ses­sion, XX15 – more alpha oscil­la­tions in work­ing mem­o­ry under speech degradation.

Final­ly, I also have the plea­sure to be a co-author on Sarah Jessen’s, who is show­ing très cool mul­ti­modal inte­gra­tion data on voic­es and bod­ies under noisy con­di­tions in the WEDNESDAY PM ses­sion, XX15.

New paper out: Alpha oscil­la­tions in audition

I am also delight­ed to report the fruits of a very recent col­lab­o­ra­tion with Nathan Weisz and his OBOB lab at the Uni­ver­si­ty of Kon­stanz, Germany.

Alpha Rhythms in Audi­tion: Cog­ni­tive and Clin­i­cal Perspectives

In this review paper, which appears in the new, excit­ing “Fron­tiers in Psy­chol­o­gy” jour­nal, we sum the recent evi­dence that alpha oscil­la­tions (here broad­ly defined from 6 to 13 Hz) are play­ing a very inter­est­ing role in the audi­to­ry sys­tem, just as they do in the visu­al and the somatosen­so­ry system.

In essence, we back Ole Jensen’s and oth­ers’ quite pari­mo­nious idea of alpha as a func­tion­al inhi­bi­tion / gat­ing sys­tem across cor­ti­cal areas.

From our own lab, pre­lim­i­nary data from two recent exper­i­ments is includ­ed: On the role of alpha osil­la­tions as a poten­tial mark­er for speech intel­li­gi­bil­i­ty and its acoustic deter­mi­nants, as well as on speech degra­da­tion and work­ing mem­o­ry load and their com­bined reflec­tion in alpha pow­er increases.

 

NB — the final pdf is still lack­ing, and Front Psy­chol is still not list­ed in PubMed. This should not stop you from sub­mit­ting to their excit­ing new jour­nals, as the review process is very fair and effi­cient and the out­reach via free avail­abil­i­ty promis­es to be considerable.
