• The goal of this study was to examine whether functional connectivity in the target region was associated with tDCS in stroke patients. -
• Considering the previous findings in the field, they acknowledged that there is high individual variability in the results of tDCS treatments and they wanted to create a model to explain the variance in tDCS treatments.
• Their hypothesis was that "stroke survivors with greater network connectivity would have a greater excitability following the tDCS"
• Their findings showed that tDCS did not increase "corticospinal excitability." They also found that "clinical characteristics and demographics are not associated with tDCS response"

Moreover, this study exemplifies the high individual variability in tDCS treatments and how the outcomes of studies involving tDCS should be examined carefully.
