Sensory motor rhythm (SMR) (12-15 Hz) originates in ventrobasal nuclei, and is related to the inhibition of afferent thalamic somatosensory information. According to recent findings of neurophysiological studies, SMR has a negative correlation to activity in the sensory motor area. Furthermore, SMR is associated with reduced external information input. Based on this evidence, it is possible that the reduction of SMR activity might be related to the concept of automaticity. However, studies have not examined the relationship between SMR neurofeedback training and precision sport performance. Therefore, this paper aimed to review neurophysiological and neurofeedback studies of SMR with hopes of formulating a possible relationship between SMR and optimal performance. Critical issues for neurofeedback studies were also included.
