Sensorimotor Robotic Measures of tDCS- and HD-tDCS-Enhanced Motor Learning in Children

open access: yesNeural Plasticity, 2018
Transcranial direct-current stimulation (tDCS) enhances motor learning in adults. We have demonstrated that anodal tDCS and high-definition (HD) tDCS of the motor cortex can enhance motor skill acquisition in children, but behavioral mechanisms remain unknown.
