Anterior intraparietal sulcus is sensitive to bottom–up attention driven by stimulus salience
Frontal eye fields (FEF) and anterior intraparietal sulcus (aIPS) are involved in the control of
voluntary attention in humans, but their functional differences remain poorly understood. We …

Neuroanatomical dissociation between bottom–up and top–down processes of visuospatial selective attention
Allocation of attentional resources to portions of the available sensory input can be
regulated by bottom–up processes, ie, spontaneous orientation towards an oncoming …

Deconstructing the architecture of dorsal and ventral attention systems with dynamic causal modeling
Attentional orientation to a spatial cue and reorientation—after invalid cueing—are mediated
by two distinct networks in the human brain. A bilateral dorsal frontoparietal network …
