Abstract
Commentary: Cumulative effects of anodal and priming cathodal tDCS on pegboard test performance and motor cortical excitability.
Highlights
Consistent with a neuroergonomics approach, task performance can be facilitated by non-invasive neuromodulation techniques, such as anodal transcranial direct current stimulation-atDCS (Clark and Parasuraman, 2014; McKendrick et al, 2015)
Protocols using Online atDCS, where the motor task is performed during the stimulation, has greater facilitative effects on motor performance/learning than if the motor task is performed after the stimulation (i.e., Offline atDCS; Stagg and Nitsche, 2011)
The results indicated that both Online atDCS conditions improved grooved pegboard test (GPT) performance over Sham after the four training blocks, only the priming cathodal tDCS (ctDCS)/Online atDCS condition further enhanced GPT performance 2 weeks later
Summary
Consistent with a neuroergonomics approach, task performance can be facilitated by non-invasive neuromodulation techniques, such as anodal transcranial direct current stimulation-atDCS (Clark and Parasuraman, 2014; McKendrick et al, 2015). Edited by: Stephen Fairclough, Liverpool John Moores University, UK These greater facilitative effects of Online atDCS on motor performance/learning are likely due to enhanced synaptic efficacy in the simultaneously engaged neural network through a “gating” mechanism (Ziemann and Siebner, 2008).
