Theta burst stimulation of dorsolateral prefrontal cortex modulates pathological language switching: A case report

▶ Neuroimaging studies had highlighted the importance of the DLPFC in language switching. ▶ The nature of language switching and its neural correlates have not been clearly established. ▶ We used TBS in a bilingual patient showing pathologic language switching. ▶ An interruption of language switching occurred after excitatory left DLPFC stimulation. ▶ Inhibitory left DLPFC TBS transiently increased the language switching. ▶ Our findings suggest that left DLPFC is actively involved in language switching. ▶ TMS techniques may help in understanding the neural bases of bilingualism.
