We are glad to announce that our paper (Math­ias Scharinger, Saman­tha Poe, & William Idsar­di) on cor­ti­cal rep­re­sen­ta­tions of Turk­ish vow­els is in press in Jour­nal of Cog­ni­tive Neu­ro­science. In this paper, we extend pre­vi­ous meth­ods of obtain­ing cen­ters of cor­ti­cal activ­i­ty evoked by vow­el exem­plars (e.g. Obleser et al., 2003, on Ger­man) and pro­vide an N1m ECD (Equiv­a­lent Cur­rent Dipole) map of the entire vow­el space of Turk­ish. Intrigu­ing­ly, ECD loca­tions mapped near­ly per­fect to loca­tions in F2/F1 space, although our mod­el com­par­i­son sug­gest­ed that inclu­sion of dis­crete fea­ture based pre­dic­tors for both loca­tions as well as col­lo­ca­tions of vow­els in audi­to­ry cor­tex improves the mod­el fits sub­stan­tial­ly. We dis­cuss the find­ings on the back­ground of neur­al cod­ing schemes for speech-relat­ed audi­to­ry categories.

UPDATE: Paper is avail­able here.
