Anodal tDCS of SMA enhances Visuomotor Learning

Background: The acquisition of a new motor skill follows two distinct stages with continuous practice. In an early phase, motor performance improves rapidly within a single training session. In a later phase, there is a slower but continuous learning rate in which slight improvements in performance are seen over several sessions of practice. These changes in learning most possibly rely on long-term potentiation (LTP) of synaptic connections. Recent evidence showed that the extent of motor skill learning can be significantly altered by non-invasive brain stimulation protocols. One way of improving motor learning…
