Control of goal-directed and stimulus-driven attention in the brain
-
In this review, the authors propose that two functionally distinct cortical circuits in humans mediate the control of voluntary and involuntary attentional control. A dorsal system that includes posterior parietal cortex and dorsal frontal cortex controls the voluntary deployment of attention. A ventral system that includes the temporoparietal junction and inferior frontal cortex is specialized for detecting unexpected salient stimuli and then interrupting ongoing voluntary attention, allowing 'automatic' redeployment of attention to salient events

Modulation of oscillatory neuronal synchronization by selective visual attention
-
The authors record from macaque cortical area V4 while the monkeys attend to a relevant stimulus and ignore an irrelevant one. Populations of neurons driven by the attended stimulus exhibit increased spiking synchrony compared to neurons driven by the unattended stimulus. The authors suggest that attention-related synchrony may cause increased efficacy in driving later stages of visual cortex

Attention modulates responses in the human lateral geniculate nucleus
-
In this study, human observers direct their attention to the left or right of a visual display while continuously fixating a central point. fMRI reveals attentional modulation of responses in the lateral geniculate nucleus of the thalamus, including enhancement of responses to attended stimuli, suppression of responses to ignored stimuli and increased baseline activity in the absence of stimulation. This is one of the first studies to find attentional modulation at this very early subcortical level, one synapse from the retina

A central arrow cue directs attention to a box in the left or right visual field where (in most trials) a target that requires a detection response appears. Sustained increases in event-related fMRI activity are observed in IPS and SFS-PrCes after the cue, suggesting that these areas provide a continuous biasing signal for maintaining spatial attention

Functional specificity of superior parietal mediation of spatial shifting
-
A bright square appears in 1 of 10 horizontally arrayed positions, and every 2.3 s it abruptly changes its location. Observers covertly attend to the square to detect a brief dimming. Thus, both stimulus-driven attentional capture (by the abrupt onset of the square) and goal-directed attentional deployment are probably recruited by this task. SPL shows a transient increase in event-related fMRI activity after spatial shifts of attention. The magnitude of the increases in SPL activity are proportional to the size of the attention shift. In a second experiment, sustained peripheral attention is contrasted with passive fixation; this identifies a network of frontal and inferior parietal areas that are active during the maintenance of attention. This study reveals the distinct patterns of cortical activity in shifting and maintaining attention

Transient neural activity in human parietal cortex during spatial attention shifts
-
Observers alternately maintain or shift attention between continuous streams of letters in the left and right visual field. Occasional digit targets in the letter streams instruct them either to maintain attention on the currently attended stream or to shift attention to the other stream. The locus of attention modulates the strength of fMRI activity in extrastriate cortical regions corresponding to the left and right attended regions. In addition, SPL shows transient increases in activity that are time-locked to the spatial attention shifts

Neuronal activity in the lateral intraparietal area and spatial attention
-
Monkeys make visual discriminations at an attended location and attempt to ignore distractors that appear at other locations. Behavioral threshold measurements show that the onset distractors transiently capture attention away from the voluntarily attended location. Single-unit recording shows that the relative magnitude of neural activity in the LIP area determines, on a moment-by-moment basis, which location in the visual field will show an attentional advantage. The authors suggest that LIP has a role in continuously representing attentional priority
