Top‐down versus bottom‐up attention differentially modulate frontal–parietal connectivity

JT Bowling, KJ Friston, JB Hopfinger - Human brain mapping, 2020 - Wiley Online Library
The moment‐to‐moment focus of our mind's eye results from a complex interplay of
voluntary and involuntary influences on attention. Previous neuroimaging studies suggest …

Anterior intraparietal sulcus is sensitive to bottom–up attention driven by stimulus salience

JJ Geng, GR Mangun - Journal of cognitive neuroscience, 2009 - direct.mit.edu
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 …

Spatial re-orienting of visual attention along the horizontal or the vertical axis

E Macaluso, F Patria - Experimental brain research, 2007 - Springer
Neuroimaging data indicate functional segregation between voluntary and stimulus-driven
control of spatial attention in dorsal and ventral fronto-parietal regions, respectively. While …

Neuroanatomical dissociation between bottom–up and top–down processes of visuospatial selective attention

B Hahn, TJ Ross, EA Stein - Neuroimage, 2006 - Elsevier
Allocation of attentional resources to portions of the available sensory input can be

S Vossel, R Weidner, J Driver, KJ Friston… - Journal of …, 2012 - Soc Neuroscience
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 …

Causal interactions in attention networks predict behavioral performance

X Wen, L Yao, Y Liu, M Ding - Journal of Neuroscience, 2012 - Soc Neuroscience
