AB Early neuroimaging and electrophysiological studies suggested that motor imageryrecruited a different network than motor execution. However, several studies haveprovided evidence for the involvement of the same circuits in motor imagery tasks, inthe absence of overt responses. The present study aimed to test whether imaginedperformance of a stop-signal task produces a similar pattern of motor-related EEGactivity than that observed during real performance. To this end, mu and beta eventrelateddesynchronization (ERD) and the Lateralized Readiness Potential (LRP) wereanalyzed. The study also aimed to clarify the functional significance of the Stop-N2and Stop-P3 event-related potential (ERPs) components, which were also obtainedduring both real and imagined performance. The results showed a common patternof brain electrical activity, and with a similar time course, during covert performance andovert execution of the stop-signal task: presence of LRP and Stop-P3 in the imaginedcondition and identical LRP onset, and similar mu and beta ERD temporal windowsfor both conditions. These findings suggest that a similar inhibitory network may beactivated during both overt and covert execution of the task. Therefore, motor imagerymay be useful to improve inhibitory skills and to develop new communicating systemsfor Brain-Computer Interface (BCI) devices based on inhibitory signals
