Influence of noninvasive brain stimulation on connectivity and local activation: a combined tDCS and fMRI study.
Eur Arch Psychiatry Clin Neurosci

Article Synopsis
- The study investigates the impact of transcranial direct current stimulation (tDCS) on executive function and resting-state connectivity in the brain, focusing on the left dorsolateral prefrontal cortex (DLPFC).
- Researchers used a double-blind design with 36 healthy participants, comparing anodal, cathodal, and sham stimulation while measuring brain activity via fMRI during and after stimulation.
- Results showed significant changes in resting-state connectivity but no effects on task-related brain activation or working memory performance, and the findings did not align with previous studies, raising questions about methodology for future research.
