BACKGROUND Unilateral spatial inattention (USI) (a.k.a. neglect, unilateral neglect, visual neglect) is a common occurrence after stroke. It can also occur subsequent to traumatic brain injury. Insult to the right inferior (posterior) parietal cortex is the structure that is virtually always involved, although other brain areas have been implicated. The major consequence of USI is that the pati...

Two pairs of experiments studied the effects of attention and of unilateral neglect on auditory streaming. The first pair showed that the build up of auditory streaming in normal participants is greatly reduced or absent when they attend to a competing task in the contralateral ear. It was concluded that the effective build up of streaming depends on attention. The second pair showed that patie...

Macaque monkeys were trained preoperatively in a visual search task. Neglect after a unilateral lesion was measured as the tendency to make errors (choices of non-target stimuli) ipsilateral to the lesion. Neglect was observed after optic tract section combined with forebrain commissurotomy (n = 6) and after parietal leucotomy, i.e. unilateral section of the white matter between the fundus of t...

[Purpose] This study aims to investigate the effects of mental practice on unilateral neglect in patients with chronic stroke. [Subjects] The subjects of this study included 30 patients with chronic unilateral neglect. [Methods] The subjects were randomly divided into either the experimental group (EG) or control group (CG). All subjects received a standard rehabilitation program. In addition t...

Neck-proprioceptive and caloric-vestibular stimulation have been shown to ameliorate the spatial bias exhibited by patients suffering from unilateral visual neglect. These interventions might in principle have their effect by biasing covert attention towards the neglected side. If so, the same interventions should also modulate covert attention in neurologically-intact subjects. However, we dem...
