“…Additionally, we also observed the reduction of BROrelated precuneal activation in MA compared to PF (Figure 4 Δ PF − Δ MA ), which is consistent with the activation of this region during mental arithmetic processing-particularly in subtraction tasks (Fehr et al, 2007;Kong et al, 2005). gyri during PF is consistent with previous reports (Berman, Horovitz, Morel, & Hallett, 2012;Bonfiglio et al, 2014;Liu et al, 2017), and may be related to sensory processing of blink-related information as these regions have been previously linked with visual processes including complex image encoding, face perception, and object recognition (Bar et al, 2001;Machielsen, Rombouts, Barkhof, Scheltens, & Witter, 2000;Weiner & Zilles, 2016). These findings help to validate the involvement of the precuneus regions in BRO effects.…”
