RESUMO:

Graph theory has been very successful in efficiently represent the relationship between objects or elements of different natures. Proposals involving its use in the characterization of brain functioning have gained prominence in neuroscience, making it possible to assist in the diagnosis of pathologies such as depression, schizophrenia, Parkinson's, attention disorders, etc. Recently, the use of strategies based on functional connectivity has shown to be an interesting option in the context of the development of brain-computer interfaces (BCIs), allowing, from electroencephalography signals acquired in the context of BCIs, the characterization of the brain electrical activity during different mental tasks, such as motor imagery (MI). Thus, the quantification and assessment of functional connectivity have been widely applied in the study of brain organization during motor tasks, with the aim of seeking a better understanding of the imagery process that allows the development of more robust BCIs. However, until now, the dynamics of the imagery process and the interaction between different brain areas over time have rarely been taken into account. Recent studies suggest that dynamic functional connectivity can provide relevant information for the discrimination between movement and rest, as well as for the distinction between different MI tasks. With this in mind, the aim of this study is to evaluate the applicability of dynamic functional connectivity in these two scenarios, rest vs MI and right hand vs left-hand imagery, by the analysis of different strategies for the estimation of functional connectivity, as well as the use of different graph metrics that allow the extraction of information relevant to the distinction of different mental states
