Description

The article's central design recommendation is that neuromodulation of targets beyond M1 during practice can improve outcomes of a low-retention practice schedule. The authors state that "neuromodulation of targets beyond M1, via application of anodal tDCS during practice, can facilitate not just the acquisition and retention of a single novel motor skill but also multiple skill memories developed simultaneously." Applying anodal tDCS at left PMd throughout repetitive practice produced an overnight offline gain matching interleaved practice.

Design Implications

Context

Requirements

• 2 mA anodal stimulation via a 25 cm2 anode placed 2.5 cm anterior to M1 (FC3/FC4) with supraorbital reference, applied for the entire 20-min practice period

Constraints

• The overnight gain emerged only for left-PMd stimulation and only following overnight sleep; no early 6-h consolidation was induced, and blinding was not formally evaluated

Target Learners

• adult learners practicing novel motor sequences (right-handed undergraduates in the study)

Learning Goals

• retention and sleep-related consolidation of novel motor sequence skills

Claims

• Left Pmd Tdcs Sleep Related Offline Gain [+M]
• Anodal Tdcs Pmd Improves Online Motor Acquisition [+M]
