“…Seven studies used bimodal stimulation (Table 1) (Callai et al, 2019;De Oliveira et al, 2019;Scarabelot et al, 2019;Cioato et al, 2016;Lopes et al, 2020;Regner et al, 2020;Santos et al, 2020) and two article used anodal current (Spezia Adachi et al al., 2012;Guo et al, 2020). In addition, the electrode position varied: seven articles used the area between the parietal cortex hemispheres (Scarabelot et al, 2019;Callai et al, 2019;Regner et al, 2020;Lopes et al, 2020;Santos et al, 2020;Cioato et al, 2016;Spezia Adachi et al, 2012), one study on the prefrontal cortex (De Oliveira et al, 2019), and one reported the application on the skullcap (Guo et al, 2020).…”
