Numerous studies indicate that during the observation and imaginary performance of movements, a decrease in the sensorimotor mu-rhythm in the central regions of the scalp reflects the degree of the mirror neuron system (MNS) activity, which ensures the perception of non-verbal signals during social interactions. Proof of the existence of the MNS in humans and subsequent invasive studies of its properties were carried out with the participation of patients with epilepsy, while the possible disruptions of the MNS in these patients were not taken into account. In this work, we analyzed the responses of the sensorimotor rhythm to the observation, imaginary performance and actual performance of various movements in patients with temporal lobe epilepsy and control group participants. It was found that mu-desynchronization is more pronounced in patients with epilepsy than in control group participants in the upper frequency (10.5 – 13 Hz) sub-band. Characteristic differences between the groups also emerged during tasks associated with movements that require two hands
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
