Unilateral spatial neglect consists of the inability of a patient to respond, orient, and attend to stimuli on the left side of a space following a right-hemisphere lesion. Many rehabilitation approaches have been proposed to reduce neglect. The aim of our study was to compare the effect of visual-scanning training (VST) and prismatic adaptation (PA) on patients with neglect following a right-hemisphere lesion. Twenty patients with left neglect were enrolled in the study. Before and after training, a comprehensive neuropsychological assessment of visuospatial abilities, evaluating personal, peripersonal, and extrapersonal neglect, was performed. After assessment, patients were alternately assigned to 1 of 2 groups, VST or PA. Both trainings consisted of 20 sessions, 1 per day, 5 days a week for 4 weeks. The results showed that both treatments improved patient neglect, especially in personal and peripersonal spaces. No difference between pretreatment and posttreatment was found in extrapersonal subscales. This finding could be due to the fact that there were no exercises requiring the use of objects within reach in either training. In conclusion, no difference between the 2 approaches was found, and both are useful rehabilitation techniques that appear to improve neglect.

The subjective visual vertical (VV), the visually estimated direction of gravity, is essential for assessing vestibular function and visuospatial cognition. In this study, we aimed to investigate the mechanisms underlying altered VV perception in stroke participants with unilateral spatial neglect (USN), specifically by examining their eye movement patterns during VV judgment tasks. Participants with USN demonstrated limited eye movement scanning along a rotating bar, often fixating on prominent ends, such as the top or bottom.

Although active exploration of environmental information is essential for specifying one's action opportunities in team sports, knowledge about the relationship between visual exploratory behaviour and successful actions in ice hockey is scarce. The purpose of this study was to investigate whether scanning prior to pass reception was associated with a higher probability of a successful outcome of the following action among professional ice hockey players. A total of 43 male and 45 female ice hockey players participated in the study.

Perception of infant faces plays a crucial role in adult-infant caretaking behaviour, with adults being found to demonstrate a reliable attraction towards infant faces over other stimuli. When affected by a congenital facial malformation such as cleft lip and/or palate, however, adults' visual scanning patterns and subjective appraisal of these faces have been found to be adversely affected. Little past work has explored how an observer's prior experience with this specific malformation might play a role in the perception of cleft-affected infant faces.

Article Synopsis
- This study aimed to adapt the Delis-Kaplan Executive System (D-KEFS) tests for the Greek population aged 20 to 49, focusing on identifying executive function impairments in adults with neurological or psychiatric issues.
- The research involved 101 healthy participants and examined how age and education influenced performance on the Color-Word Interference Test (CWIT) and Trail Making Tests (TMTs), finding that age and education impact results but gender does not.
- The developed norms for the Greek adult population will assist clinicians in diagnosing executive function deficits and help in tailoring appropriate treatment strategies, while also being useful for further research.
Alpha transcranial alternating current stimulation as add-on to neglect training: a randomized trial.

Visuospatial neglect is a common and debilitating condition following unilateral stroke, significantly impacting cognitive functioning and daily life. There is an urgent need for effective treatments that can provide clinically relevant and sustained benefits. In addition to traditional stroke treatment, non-invasive brain stimulation, such as transcranial alternating current stimulation, shows promise as a complementary approach to enhance stroke recovery.
