Hypothesis
This study aimed to investigate the effects of a-tDCS and c-tDCS applied over the PFC for healthy populations on reactive and proactive control processes compared with sham or no tDCS conditions.
Conclusion
This review confirmed the engagement of PFC tDCS in reactive and proactive inhibitory processes.
Supporting Evidence
- A-tDCS and c-tDCS over the PFC had significant ergogenic effects on SST performance.
- A-tDCS had a positive effect on GNG task performance.
- The meta-analysis revealed that the application of a-tDCS over the right IFC can significantly improve proactive inhibition.
Takeaway
This study looked at how brain stimulation can help people control their actions better. It found that certain types of stimulation can make it easier to stop yourself from doing things you shouldn't.
Methodology
This systematic review was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, including studies that assessed inhibitory control in SST or/and GNG tasks.
Potential Biases
The study did not make a detailed comparative discussion and analysis of stimulation parameters and potential moderators.
Limitations
The participants included in the studies were all healthy populations, and the meta-analysis did not perform subgroup analysis in specific regions of PFC.
Participant Demographics
The study included 484 males and 620 females, with ages ranging from 18 to 35 years.
