Brain activation in motor sequence learning – the role of variability in input and output space

Cortical excitability may be subject to changes through training and learning. Somatosensory learning can increase cortical excitability in somatosensory cortex, an effect which correlates with learning success. Facilitation of motor cortical exitability has been shown to be positively correlated with improvements in performance in simple motor tasks. Thus cortical excitability may be another marker of learning and use-dependent plasticity. Previous studies focussed on the change in cortical excitability brought about by learning processes, therefore the relation between the native level of cortical excitability…
