“…First, although some monocular cues (e.g. occlusion, relative size) can contribute to depth perception (Cutting, 1997;Hillis, Watt, Landy, & Banks, 2004), such pictorial cues generally do not provide precise quantitative information about depth (Kim, Angelaki, & DeAngelis, 2016). Stereovision (also referred to as binocular vision or stereoscopic vision) then maximises the number and nature of visual cues, and increases the presence (Craig, 2013;Howard, 2012) and embodiment (Kilteni et al, 2012) of participants interacting with a VE.…”

Virtual reality (VR) is a widespread technology drawing an increasing interest for players and coaches, especially in team ball sports as it offers a simple tool to simulate, analyse and train situations that are often too complex to reproduce in the field. In this review we aimed at (1) providing an overview of methodologies and outcomes of research studies using VR in team ball sports; (2) better evaluating the potential interest of VR to analyse or train team ball sports situation and (3) identifying limitations, gaps in knowledge and remaining scientific challenges. The MEDLINE and Web of Science Core Collection databases were searched, using predefined combinations of keywords. Thirty articles were retained and analysed. VR can be an interesting tool to assess or train team ball sports skills/situations as it allows researchers to control and standardise situations and focus on specific skills/subskills. Studies that used VR in team ball sports still have some limitations, mainly due to technical issues or study design. This paper also describes the way VR should be used to enhance understanding of performance in team ball sports. Additional suggestions for future research and study design are proposed.

“…The cortical visual processing network includes dorsal and ventral pathways. The middle temporal gyrus is a key node in the dorsal pathway, which involves in visuospatial functions and visual motion [29][30][31] . The middle frontal gyrus and superior frontal gyrus take part in the oculomotor control, which is closely related to dorsal and ventral pathways.…”

Background: Dysthyroid optic neuropathy (DON) is a serious complication of thyroid-associated ophthalmology (TAO), leading to loss of vision or blindness. Numerous studies had reported thyroid dysfunction affects a wide range of visual pathways in adults, from the retina to the visual center. We aimed to explore if there were abnormalities of gray matter density (GMD) in DON patients.Methods: We collected patients with TAO from The Eye Hospital of Wenzhou Medical University. All patients underwent routine ophthalmic examination, Clinical Activity Score (CAS), intraocular pressure (IOP), exophthalmos, visual field, OCT,and orbital CT scan. 16 patients with DON and 16 patients without DON (N-DON) were enrolled in this study. Age, gender, orbital congestion index and degree of education of patients were matched between the two groups. High-resolution magnetization-prepared rapid acquisition with gradient echo (MPRAGE) scans was performed on all patients. Voxel-based morphometry (VBM) was applied to analyze the T1 weighted images of the brain, based on functional magnetic resonance imaging (FMRI) integrated VBM (FSL-VBM).Results: GDM was significantly decreased in the right middle temporal gyrus, left middle frontal gyrus, left superior frontal gyrus, and right middle frontal orbicular gyrus in the DON when compared to N-DON.Conclusions: The DON can result in reduced GMD in specific areas of the brain. This finding suggests that there may be other mechanisms in Don

“…cells based on their disparity and speed tuning, which may differ from cells with same name reported in existing physiological studies. For example, the properties of congruent and opposite cells shown by Nadler et al (2013) and Kim et al (2016) are based on the consistency between depth tuning and motion parallax during self-motion with eye movements. Because we do not model eye movements and our viewing geometry differs from that of Nadler et al (2013) and Kim et al (2016), we caution against direct comparisons between the cell populations unless evidence is produced to substantiate such a connection.…”

Figure 3, a and b, shows that the suppression drops off as tuning in any particular dimension becomes more dissimilar among units that share RFs in the same visuotopic region of the visual field (i.e., in the same MTϪ/MSTv macrocolumn).…”

Walking and other forms of self-motion create global motion patterns across our eyes. With the resulting stream of visual signals, how do we perceive ourselves as moving through a stable world? Although the neural mechanisms are largely unknown, human studies (Warren and Rushton, 2009) provide strong evidence that the visual system is capable of parsing the global motion into two components: one due to self-motion and the other due to independently moving objects. In the present study, we use computational modeling to investigate potential neural mechanisms for stabilizing visual perception during self-motion that build on neurophysiology of the middle temporal (MT) and medial superior temporal (MST) areas. One such mechanism leverages direction, speed, and disparity tuning of cells in dorsal MST (MSTd) to estimate the combined motion parallax and disparity signals attributed to the observer's self-motion. Feedback from the most active MSTd cell subpopulations suppresses motion signals in MT that locally match the preference of the MSTd cell in both parallax and disparity. This mechanism combined with local surround inhibition in MT allows the model to estimate self-motion while maintaining a sparse motion representation that is compatible with perceptual stability. A key consequence is that after signals compatible with the observer's self-motion are suppressed, the direction of independently moving objects is represented in a world-relative rather than observer-relative reference frame. Our analysis explicates how temporal dynamics and joint motion parallax-disparity tuning resolve the world-relative motion of moving objects and establish perceptual stability. Together, these mechanisms capture findings on the perception of object motion during self-motion.
