Several recent studies have reported results consistent with the notion that the frontoparietal network is involved in the top-down control of nonspatial attention as well as spatial attention (Shulman et al., 1999, 2002; Weiss-man et al., 2002).

WebTop-down control is described by Melloni et al. (2012) as the influence of our inner goals on stimulus selection. This was manipulated by presenting trials of different degrees of bottom-up salience either in blocks or randomly intermixed. Results indicated that primary visual cortex (V1) encodes only bottom-up salience, V2 encodes only top ...
