Hemispatial neglect, electroencephalographic correlates and the effect of short wavelength light on spatial inattention

Hemispatial neglect is a common and disabling neurological syndrome defined as the inability to detect, respond to, and orient towards stimuli contralateral to cerebral damage. Despite decades of research, the disorder is not well understood and the underlying physiology that influences the behavioural phenotype remains unclear. This lack of understanding has hampered the development of effective rehabilitation strategies. One perspective that could provide useful insights is that of perceptual decision-making. We investigated how perceptual decision-making and specifically the neural correlates associated with orienting of attention and evidence accumulation are affected by healthy aging and in patients with neglect.
