Wirth, Miranka; Abdel Rahman, Rasha; Kuenecke, Janina; Koenig, Thomas; Horn, Helge; Sommer, Werner; Dierks, Thomas – Neuropsychologia, 2011
Excitatory anodal transcranial direct current stimulation (A-tDCS) over the left dorsal prefrontal cortex (DPFC) has been shown to improve language production. The present study examined neurophysiological underpinnings of this effect. In a single-blinded within-subject design, we traced effects of A-tDCS compared to sham stimulation over the left…

Gebauer, Daniela; Enzinger, Christian; Kronbichler, Martin; Schurz, Matthias; Reishofer, Gernot; Koschutnig, Karl; Kargl, Reinhard; Purgstaller, Christian; Fazekas, Franz; Fink, Andreas – Neuropsychologia, 2012
Studies investigating reading and spelling difficulties heavily focused on the neural correlates of reading impairments, whereas spelling impairments have been largely neglected so far. Hence, the aim of the present study was to investigate brain structure and function of children with isolated spelling difficulties. Therefore, 31 children, aged…

Meinzer, Marcus; Flaisch, Tobias; Wilser, Lotte; Eulitz, Carsten; Rockstroh, Brigitte; Conway, Tim; Gonzalez-Rothi, Leslie; Crosson, Bruce – Journal of Cognitive Neuroscience, 2009
As we age, our ability to select and to produce words changes, yet we know little about the underlying neural substrate of word-finding difficulties in old adults. This study was designed to elucidate changes in specific frontally mediated retrieval processes involved in word-finding difficulties associated with advanced age. We implemented two…
