This study uses dual-coil paired-pulse TMS to show a spatially specific facilitatory connection between the supplementary motor complex and primary motor cortex in humans.

This study compares motor sequence learning performance between caffeine consumers and non-consumers, finding faster response times in the caffeine group.

This study examines the combined effects of pharmacological agents and intermittent theta-burst stimulation on motor sequence learning in humans, finding that lorazepam with iTBS impairs retention.

This study compares motor evoked potential amplitudes at C3, C3h, and C1 to determine the best target for the motor hand area, finding C3h and C1 provide larger responses than C3.

This study tests the effect of transcranial direct current stimulation (tDCS) at different times relative to motor training on skill learning, finding no significant difference in performance gains compared to a control group.
