Human ability to attend to visual stimuli based on their spatial locations requires the parietal cortex. One hypothesis maintains that parietal cortex controls the voluntary orienting of attention toward a location of interest. Another hypothesis emphasizes its role in reorienting attention toward visual targets appearing at unattended locations. Here, using event-related functional magnetic resonance (ER-fMRI), we show that distinct parietal regions mediated these different attentional…

Mechanistic links that exist in advanced brains between processes that regulate conscious attention, seeing, and knowing, and those that regulate looking and reaching are described.
Visual working memory in health and disease
Overall, this thesis explores how visual working memory is updated dynamically across time according to attentional priority in health, how these processes are affected in patients with visual neglect following right hemisphere stroke and in those with medial temporal lesions, and how a dopamine agonist might ameliorate visual neglect by modulating selective attention.
Activity in right temporo-parietal junction is not selective for theory-of-mind.
Functional neuroimaging was used to examine the extent to which cortical loci identified by a "theory-of-mind localizer" also distinguish between trials on a target detection task that varied demands to reorient attention, and results were incompatible with claims of RTPJ selectivity for mental state attribution.
Differential cortical activation during voluntary and reflexive saccades in man
Busy and confused? High risk of missed alerts in the cockpit: an electrophysiological study
The results showed that both mental and auditory loads affected tone detection performance, and increased mental load, auditory load, and miss rate, were all associated with disrupted brain response to the target tone as showed by reductions of the P3b amplitude.

Toward a principled explanation of unilateral neglect
There is little theoretical consensus and it is possible that many distinct impairments have been conflated under the label of “unilateral neglect,” although there are numerous (potentially competing) hypotheses that emphasise “perceptual” and “representational” factors.
The disengagement of covert attention and the neglect syndrome
A very strong relationship between clinical neglect and impairment of the disengagement operation across patients, and longitudinally, within patients is found and it is found that right-hemisphere lesions cause greater impairment in the disengage process than do left-hemispheric lesions.

According to this model, complex behavior is mapped at the level of multifocal neural systems rather than specific anatomical sites, giving rise to brain‐behavior relationships that are both localized and distributed.
Visual scanning training effect on reading-related tasks in acquired right brain damage.
The results suggest that the academic disorders found in right brain damage can be treated as secondary to a primary disturbance in visual scanning behavior.

Effectiveness of neglect rehabilitation in a randomized group study.
The effectiveness of neglect rehabilitation training has been studied in two randomly selected groups of right brain-damaged patients and it is concluded that the rehabilitation program produces significant results, which generalize to situations similar to those of everyday life.
