Abstract:
Objective To explore the effect of transcranial direct current stimulation(tDCS)on re-sponse inhibition using behavioral and electroencephalographic(EEG)measures.Methods Twenty-eight healthy university students majoring in physical education were recruited and randomly assigned to ei-ther a verum tDCS group or a sham tDCS group.The study employed a Go/No-go task paradigm,with tDCS serving as the intervention.Event-related potentials(ERPs)were utilized to compare and analyze the changes in response inhibition performance between the two groups before and after the in-tervention.Results 1)After tDCS intervention,Go reaction time of the verum tDCS group was signifi-cantly shorter compared to baseline(P<0.05),while no significant differences were found in Go accu-racy or No-go accuracy.However,no significant changes were found in the above measurements of the sham group.2)As to EEG,during the Go task,the verum tDCS group exhibited significantly larger P3 amplitudes and significantly shorter P3 latencies over the central-parietal region after interven-tion(P<0.05),while the sham group showed no significant differences.In the No-go task,the former group showed significantly shorter P3 latencies after intervention(P<0.05),with no significant changes observed in the sham group.Inter-group comparisons revealed no significant differences in any base-line measures.However,after the intervention,the verum tDCS group demonstrated significantly short-er P3 latencies in the Go task than the sham group(P<0.05),with no significant differences in P3 amplitude during the Go task,or in P3 amplitude and latencies during the No-go task.Conclusion The tDCS intervention leads to faster response speed,enhances inhibitory control,improves processing efficiency,and recruits more attentional resources,indicating a moderate improvement in response inhi-bition performance.
