The process of learning a new motor skill can be divided into different phases. The initial learning phase (online) is followed by an offline phase (consolidation) during which the training-acquired motor engram is transformed into a more robust representation in the absence of further task practice. This presentation will highlight results from a series of experiments in which we employ different non-invasive brain stimulation techniques (tDCS, tACS and TMS) in an effort to better understand and possibly enhance offline motor memory consolidation. Results will be discussed in the context of the growing debate of whether non-invasive brain stimulation is a viable and effective avenue to enhance motor learning and consolidation processes in both healthy and pathological populations.
