Abstract

Motor learning involves reinforcement processes that regulate motor responses. To test whether outcomes of past movements influence outcomes of future movements, we conducted a human motor learning study and recorded oscillatory brain signals with electroencephalography (EEG). Our results show that motor variability is largely influenced by previous motor outcomes. Motor variability is increased when previous outcomes were unsuccessful while it is decreased when outcomes were successful. Time frequency analyses and cluster-based permutation tests of EEG signals showed greater frontal beta oscillations during feedback presentation when outcomes were successful. The results suggest a role of the frontal cortex for the regulation of motor variability in human subjects.
