“…It is widely accepted and several studies have reported similar results, in many of its variations (Jewell and McCourt, 2000 for a review; Ferber and Karnath, 2001; Longo and Lourenco, 2006; Rorden et al, 2006). Very few studies have simulated the line bisection task in an immersive virtual environment (Baheux et al, 2006; Garrison and Ellard, 2009). Therefore, our aim was to employ this paradigm to test the feasibility of our technical proposal for registering fNIRS signals in an immersive VR environment.…”

For over two decades Virtual Reality (VR) has been used as a useful tool in several fields, from medical and psychological treatments, to industrial and military applications. Only in recent years researchers have begun to study the neural correlates that subtend VR experiences. Even if the functional Magnetic Resonance Imaging (fMRI) is the most common and used technique, it suffers several limitations and problems. Here we present a methodology that involves the use of a new and growing brain imaging technique, functional Near-infrared Spectroscopy (fNIRS), while participants experience immersive VR. In order to allow a proper fNIRS probe application, a custom-made VR helmet was created. To test the adapted helmet, a virtual version of the line bisection task was used. Participants could bisect the lines in a virtual peripersonal or extrapersonal space, through the manipulation of a Nintendo Wiimote ® controller in order for the participants to move a virtual laser pointer. Although no neural correlates of the dissociation between peripersonal and extrapersonal space were found, a significant hemodynamic activity with respect to the baseline was present in the right parietal and occipital areas. Both advantages and disadvantages of the presented methodology are discussed.

“…Several of the tasks were specifically built for the assessment and other, more entertaining tasks for the rehabilitation. For the experiment presented in this paper, we used a virtual replica of the paper and pencil tests that was built to test new rehabilitation techniques and to provide a precise characterization of the neglect [6]. The assessment is based on the combination of performance and the eye-gaze pattern of the subject.…”

Background: Hemispatial neglect is a cognitive disorder defined as a lack of attention for stimuli contra-lateral to the brain lesion. The assessment is traditionally done with basic pencil and paper tests and the rehabilitation programs are generally not well adapted. We propose a virtual reality system featuring an eye-tracking device for a better characterization of the neglect that will lead to new rehabilitation techniques.

“…Old and favoured paper-and-pencil tests like line-bisection and cancellation tests in neglect have been converted to computer-based versions which have led to increased sensitive to the symptoms of neglect [51][52][53][54][55], as well as expansions of said tests to include observations and assessment of aberrant behaviour [54,[56][57][58][59][60][61], and the detection and separation of multiple disorders [62]. New assessment techniques have also been introduced e.g.…”

Since the emergence of computers, it has been recognized that they might play a role in brain rehabilitation efforts. However, the complexity of cognitive skills combined with the challenges of translating into software the skilled, therapeutic activities relating to rehabilitation of brain injury have prevented real breakthroughs in the area of relearning and retraining of cognitive abilities. The real potential of advanced technology has so far not been unleashed in current implementations of training resulting in lack of long-term efficacy and generalization of training. This paper will attempt to provide an overview of some the challenges facing anyone entering the exiting field of training for cognitive recovery and propose a way forward for future cognitive rehabilitation using advanced computer technology.
