However, little research has demonstrated the influence of the eyes-closed condition on the motor cortex, particularly during a self-paced movement. This prompted the question: How does the motor cortex activity change between the eyes-closed and eyes-open conditions? To answer this question, we recorded EEG signals from 15 voluntary healthy subjects who performed a simple motor task (i.e., a voluntary isometric flexion of the right-hand index) under two conditions: eyes-closed and eyes-open. Our results confirmed strong modulation in the mu rhythm (7\u201313 Hz) with a large event-related desynchronisation. However, no significant differences have been observed in the beta band (15\u201330 Hz). Furthermore, evidence suggests that the eyes-closed condition influences the behaviour of subjects. This study gives us greater insight into the motor cortex and could also be useful in the brain-computer interface (BCI) domain.<\/jats:p>","DOI":"10.7717\/peerj.4492","type":"journal-article","created":{"date-parts":[[2018,3,15]],"date-time":"2018-03-15T04:47:33Z","timestamp":1521089253000},"page":"e4492","source":"Crossref","is-referenced-by-count":28,"title":["Electroencephalographic
