Cognitive functions of the posterior parietal cortex: top-down and bottom-up attentional control
- Biology, PsychologyFront. Integr. Neurosci.
This review is focused on recent neuroimaging and neuropsychological studies elucidating the cognitive roles of dorsal and ventral regions of parietal cortex in top-down and bottom-up attentional orienting, and on the interaction between the two attentional allocation mechanisms.
The influence of posterior parietal cortex on extrastriate visual activity: A concurrent TMS and fast optical imaging study
Serial Organization of Human Behavior in the Inferior Parietal Cortex
- Biology, PsychologyThe Journal of Neuroscience
The central role of the bilateral intraparietal sulcus in high-order sequential cognition is revealed and a major functional segregation within the frontoparietal network mediating action planning is suggested, with the frontal and parietal sector involved in processing the hierarchical and serial structure of action plans, respectively.
Motor role of parietal cortex in a monkey model of hemispatial neglect
- Biology, PsychologyProceedings of the National Academy of Sciences
Significance Humans and animals often choose between targets in space. Parietal cortex is known to be critical to this function. However, the exact role of parietal cortex in spatial choice remains…
The Attention Systems of the Human Brain
- Psychology, Biology
This introductory chapter presents a brief overview of attention processes, with their putative neural bases in the human brain, as a heterogeneous set of processes that allow to select and act on external or internal sources of information and produce behavior which can take into account both the authors' goals and the occurrence of unexpected events.

The dorsal attentional system in oculomotor learning of predictive information
- Psychology, BiologyFront. Hum. Neurosci.
The current findings from the literature suggest that the FEFs may be more involved in top-down spatial attention, whereas the parietal cortex is involved in processing task-relevant attentional influences driven by stimulus salience.

Frontoparietal cortical networks for directing attention and the eye to visual locations: identical, independent, or overlapping neural systems?
- Psychology, BiologyProceedings of the National Academy of Sciences of the United States of America
Functional anatomical and single-unit recording studies indicate that a set of neural signals in parietal and frontal cortex mediates the covert allocation of attention to visual locations, as…
Functional Organization of Human Intraparietal and Frontal Cortex for Attending, Looking, and Pointing
- Biology, PsychologyThe Journal of Neuroscience
Surface-based registration of macaque cortical areas onto the map of fMRI responses suggests a relatively good spatial correspondence between human and macaque parietal areas, and large interspecies differences were noted in the topography of frontal areas.
Spatial attention deficits in humans: a comparison of superior parietal and temporal-parietal junction lesions.
- Psychology, BiologyNeuropsychology
Two groups of patients selected for lesions at the temporal-parietal junction including the superior temporal gyrus, or for lesions involving the parietal but not the inferior temporal region, performed cued-target detection tasks, suggesting that separate mechanisms mediate exogenous and endogenous processes during attention shifts.
Parietal activation during visual search in the absence of multiple distractors
- Biology, PsychologyNeuroreport
A subset of parietal regions participates in the control of visual search even in the absence of distractors, according to fMRI results.
Spatial awareness is a function of the temporal not the posterior parietal lobe
- Biology, PsychologyNature
It is shown that, contrary to the widely accepted view, the superior temporal cortex is the neural substrate of spatial neglect in humans, as it is in monkeys.

Control of goal-directed and stimulus-driven attention in the brain
- Psychology, BiologyNature Reviews Neuroscience
Evidence for partially segregated networks of brain areas that carry out different attentional functions is reviewed, finding that one system is involved in preparing and applying goal-directed selection for stimuli and responses, and the other is specialized for the detection of behaviourally relevant stimuli.

Transient neural activity in human parietal cortex during spatial attention shifts
- Biology, PsychologyNature Neuroscience
Brain activity during attention shifts using rapid, event-related fMRI of human observers as they covertly shifted attention between two peripheral spatial locations suggests that activation of the parietal cortex is associated with a discrete signal to shift spatial attention, and is not the source of a signal to continuously maintain the current attentive state.
