Outline of Final Research Achievements

We published four papers throughout the study period: the first showed that transcranial alternating current stimulation (tACS) of the cerebellum and supplementary motor cortex improved bimanual fine motor skills; the second showed that transcranial direct current stimulation of the interparietal sulcus region improved response inhibition; the third showed that tACS during brief rest during motor practice improved motor learning; and the fourth showed that transcranial direct current stimulation of the parietal cortex improved motor learning. The third part of the study revealed that tACS during a short rest period during motor practice had an effect on motor learning. The fourth study revealed that the effect of tACS on supplementary motor cortex during the rest period during motor learning depended on the original motor skill and learning efficiency, and was published in Frontiers in Behavioral Neuroscience.
