Resumo
The mirror neuron system (MNS) has been a captivating area of research since its discovery in macaque monkeys [1]. Researchers have established the role and presence of the human auditory mirror system in both empathy [2] and musical creativity [3]. As well, the mirror system allows to learn new behaviors by observation, facilitating knowledge acquisition and action understanding. In addition, research has indicated the influence of stimulus valence on the human MNS [4]. The human brain is sensitive to the positive valence of words, and this reactivity may vary with the strength of the valence compared to negative words. Additionally, it can perceive differences in valence for negative stimuli and words. However, what about emotional words that are auditory? Do these words’ valence, whether positive, negative, or neutral, impact auditory mirror neurons and cortical excitability? The study examines how auditory words of different valences affect the MNS and cortical activity. This novel approach uses auditory stimuli to examine the role of mirror neurons in neuromodulation through a transcranial magnetic stimulation (TMS) protocol, which has not been done in previous investigations. The results of this study suggest that both positive and negative words will induce greater excitability [4], as evidenced by motor evoked potentials. The results of this study will have broad applications. Firstly, it will offer a new contribution to the investigation of mirror neurons through TMS protocol. Secondly, inferences can be drawn and applied in the field of therapeutics, where language is used as a tool to mediate the process. In general, it will increase personal awareness of language in daily communication, leading to an enhanced communication process. Furthermore, the study’s findings imply the existence of auditory mirror neurons and their pivotal role in comprehending the emotional valence of different words, thereby influencing our feelings. This will advance our understanding of the human brain and empower us to make informed decisions.
The study is being conducted with the HSE Automated system for non-invasive brain stimulation, which allows for simultaneous recording of brain activity and eye movement.
