Whole-brain functional magnetic resonance imaging (MRI) was used to examine the neural substrates of internally (endogenous) and externally (exogenous) induced covert shifts of attention. Thirteen normal subjects performed three orienting conditions: endogenous (location of peripheral target predicted by a central arrow 80 of the time), exogenous (peripheral target preceded by a noninformative peripheral cue), and control (peripheral target preceded by noninformative central cue). Behavioral… Expand

Differential cortical activation during voluntary and reflexive saccades in man
TLDR
This is the first study to demonstrate preferential activation of an area in its posterior part, the right angular gyrus, during production of exogenously triggered rather than endogenously generated saccades, a finding which is proposed to be consistent with an important role for theangular gyrus in exogenous saccadic orienting.

The link between covert attention and saccade programming
In the present study, we investigated the distribution of attention before antisaccades. We used a dual task paradigm, in which participants made prosaccades or antisaccades and discriminated the… Expand

Anterior Intraparietal Sulcus is Sensitive to Bottom–Up Attention Driven by Stimulus Salience
  • J. Geng, G. Mangun
  • Medicine, Computer Science
  • Journal of Cognitive Neuroscience
  • 2009
TLDR
Separable roles for FEF and aIPS in attentional control are demonstrated with FEF more involved in goal-directed spatial attention and a IPS relatively more sensitive to bottom–up attentional influences driven by stimulus salience. Expand
Neuronal modulation of auditory attention by informative and uninformative spatial cues
TLDR
Healthy adults who underwent event‐related FMRI while performing a task that manipulated automatic and more controlled auditory orienting were studied, finding that the auditory modality may be more biased toward automatic shifts of attention following uninformative cues. Expand
The role of parietal cortex during sustained visual spatial attention
TLDR
A functional-anatomic organization of parietal cortex where shifts in attention are mediated by superior regions and sustained attention is mediated by more lateral regions is suggested. Expand
Abnormal inhibition of return: A review and new data on patients with parietal lobe damage
TLDR
The hypothesis that a spatial “disengagement deficit” (DD) contributed to the pattern of impaired IOR in the ipsilesional field of parietal patients is investigated and interpreted in terms of unilateral parietal damage leading to an imbalance of the relative salience of signals represented in a spatial map for directing attention. Expand
Endogenous and exogenous attention shifts are mediated by the same large-scale neural network
TLDR
It is concluded that endogenous and exogenous orienting are mediated by the same large-scale network of frontal and parietal brain areas. Expand
Monocular channels have a functional role in endogenous orienting
TLDR
The data provides converging evidence for the notion that endogenous facilitation is modulated by monocular portions of the visual stream and suggests that higher cortical mechanisms are not exclusively responsible for endogenous orienting, and that a dynamic interaction between higher and lower neural levels, might be involved. Expand
Interaction between spatial inhibition of return (IOR) and executive control in three-dimensional space
TLDR
Significantly reversed response-level conflicts were observed at the cued location in the farther depth plane, indicating that spatial IOR toward the fartherdepth plane was more than a simple effect of attentional orienting. Expand

TLDR
The two attention tasks evoked largely overlapping patterns of neural activation, supporting the existence of a general neural system for visuospatial attention with regional functional specialization. Expand

  • 1996
TLDR
The location and possible function of the human frontal eye-field (FEF) were evaluated by reviewing results of cerebral blood-flow (CBF) and lesion studies and it is proposed that future research on FEF function in human subjects may benefit from focusing on the visuomotor rather than the cognitive aspects of oculomotor control.

Improved Assessment of Significant Activation in Functional Magnetic Resonance Imaging (fMRI): Use of a Cluster‐Size Threshold
TLDR
Monte Carlo simulations and fMRI studies of human subjects have been used to verify that this approach can improve statistical power by as much as fivefold over techniques that rely solely on adjusting per pixel false positive probabilities. Expand
A PET study of visuospatial attention
TLDR
PET findings indicate that parietal and frontal regions control different aspects of spatial selection, and the functional asymmetry in superior parietal cortex may be relevant for the pathophysiology of unilateral neglect. Expand
Neural control of saccadic eye movements
TLDR
The puzzling literature on the role of vermal lobules VIc, VII and the fastigial nuclei in the control of saccadic eye movements is reviewed and a testable hypothesis about how theFastigial projection to inhibitory burst neurons could modify saccade metrics is suggested. Expand

Overlap of attention and movement-related activity in lateralized event-related brain potentials
TLDR
It is concluded that the anterior spread of the N2pc from its occipito-temporal maximum to central electrode sites is probably due to simultaneous attention-related activity in posterior and central brain areas. Expand

It is suggested that a strict dorsal/ventral dual-stream model does not fully account for the perception of novel objects in space. Expand
Attention Mechanisms in Visual SearchAn fMRI Study
TLDR
Using functional magnetic resonance imaging (fMRI), it is shown that the cerebral networks involved in efficient and inefficient search overlap almost completely, and it is likely that visual search does not require serial processing, otherwise the existence of a serial searchlight that operates in the extrastriate cortex but differs from the visuospatial shifts of attention involving the parietal and frontal regions is assumed.
