    Related ArticlesModulating Motor Learning through Transcranial Direct-Current Stimulation: An Integrative View. Front Psychol. 2016;7:1981 Authors: Ammann C, Spampinato D, Márquez-Ruiz J Abstract Motor learning consists of the ability to improve motor actions through practice playing a major role in the acquisition of skills required for high-performance sports or motor function recovery after brain lesions. During the last decades, it has been reported that transcranial direct-current stimulation (tDCS), consisting in applying weak direct current through the scalp, is able of inducing polarity-specific changes in the excitability of cortical neurons. This low-cost, painless and well-tolerated portable technique has found a ... read more

Front Integr Neurosci. 2017;11:35 Authors: Deroche MLD, Nguyen DL, Gracco VL Abstract The inferior parietal lobe (IPL) is a region of the cortex believed to participate in speech motor learning. In this study, we investigated whether transcranial direct current stimulation (tDCS) of the IPL could influence the extent to which healthy adults (1) adapted to a sensory alteration of their own auditory feedback, and (2) changed their perceptual representation.

Front Hum Neurosci. 2017;11:16 Authors: Kaminski E, Hoff M, Rjosk V, Steele CJ, Gundlach C, Sehm B, Villringer A, Ragert P Abstract Older adults frequently experience a decrease in balance control that leads to increased numbers of falls, injuries and hospitalization. Therefore, evaluating older adults' ability to maintain balance and examining new approaches to counteract age-related decline in balance control is of great importance for fall prevention and healthy aging.

Psychol Res. 2018 May;82(3):496-506 Authors: Carter MJ, Smith V, Carlsen AN, Ste-Marie DM Abstract A distinct learning advantage has been shown when participants control their knowledge of results (KR) scheduling during practice compared to when the same KR schedule is imposed on the learner without choice (i.e., yoked schedules). Although the learning advantages of self-controlled KR schedules are well-documented, the brain regions contributing to these advantages remain unknown.

J Neurosci. 2017 08 02;37(31):7500-7512 Authors: Waters S, Wiestler T, Diedrichsen J Abstract What is the role of ipsilateral motor and premotor areas in motor learning? One view is that ipsilateral activity suppresses contralateral motor cortex and, accordingly, that inhibiting ipsilateral regions can improve motor learning. Alternatively, the ipsilateral motor cortex may play an active role in the control and/or learning of unilateral hand movements. We approached this question by applying double-blind bihemispheric transcranial direct current stimulation (tDCS) over both contralateral and ... read more
