“…As future direction, we can list the main recommended aspects that surround and must follow attention detection/investigation through EEG-signal: identify attention allocation through N100, N200, P100 and P300 in fronto-central-occipital brain areas (Vogt et al, 2015;Jaquess et al, 2017); P300 in fronto-parietal brain areas (Rohani and Puthusserypady, 2015;Vogt et al, 2015;Yu et al, 2015;Causse et al, 2016;Chen et al, 2016;Lamti et al, 2016;Jaquess et al, 2017;Chung et al, 2018;Li et al, 2020d) and SSVEP component in occipital area (Leite et al, 2018;Chu and D'Zmura, 2019) as we cited in Figure 3; x. Investigate attention by means of brain waves increase, decrease and beta (12-31.25 Hz)/theta (3-8 Hz) ratio in fronto-parietal brain areas, θ (Clemente et al, 2014;Fuentes-García et al, 2019;Lim et al, 2019), in occipital area, θ (Savage et al, 2013), in frontal area, αβθδ (Clemente et al, 2014;Cowley and Ravaja, 2014;Jagannath and Balasubramanian, 2014;Yin and Zhang, 2014;Lee et al, 2015;Hazarika et al, 2018;Lim et al, 2019;Li et al, 2020d) as we cited in Figure 3.…”
