Brain electrical signals allow the brain mechanisms underlying cognitive processes to be subjected to analysis. The present literature review aims to present the results of the most recent studies on brain signals involved in cognition. The literature search was performed using databases such as Google Scholar, Jama Neurology and PubMed. Twelve studies conducted between 2015 and 2020 were selected. The findings report that the processing of brain electrical signals is variable and that such variability is linked to the specific demands and difficulty levels of cognitive tasks.
