Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
However, at present, it is not known what effect tDCS has on higher-level language skills like discourse production (i.e. story telling, giving instructions) in healthy, older speakers. Therefore, the aim of this study is to investigate in healthy older adults, the effect of tDCS on discourse production as well as the ideal tDCS electrode placement for improving language at the discourse level. It is hypothesised that tDCS will result in greater language changes and improvements during discourse production compared to no stimulation.

anodal tDCS on the left inferior frontal gyrus (IFG)
Transcranial direct-current stimulation (tDCS)
Transcranial direct-current stimulation is a non-invasive brain stimulation method that can modify spontaneous cortical activity in targeted brain regions. Anodal tDCS delivered through a positively charged electrode has been found to increase cortical excitability in a targeted brain region. Application of tDCS has been found to improve language production in healthy and brain-injured speakers.
anodal tDCS on the right IFG
Transcranial direct-current stimulation (tDCS)
Transcranial direct-current stimulation is a non-invasive brain stimulation method that can modify spontaneous cortical activity in targeted brain regions. Anodal tDCS delivered through a positively charged electrode has been found to increase cortical excitability in a targeted brain region. Application of tDCS has been found to improve language production in healthy and brain-injured speakers.
