Abstract

IntroductionThe vestibular system’s contribution to spatial learning and memory abilities may be clarified using the virtual Morris Water Maze Task (vMWMT). This is important because of the connections between the vestibular system and the hippocampus area. However, there is ongoing debate over the role of the vestibular system in developing spatial abilities. This study aimed to evaluate the relationship between Dynamic Visual Acuity (DVA) across three planes and spatial abilities.MethodsThis cross-sectional study was conducted with 50 healthy adults aged 18 to 55 with normal stress levels and mental health and no neurological, audiological, or vestibular complaints. The Trail-Making Test (TMT) Forms A and B for the assessment of executive functions, the DVA test battery for the evaluation of visual motor functions, and the Virtual Morris Water Maze Test (vMWMT) for the assessment of spatial learning and spatial memory were performed. All participants also underwent the Benton Face Recognition Test (BFRT) and Digit Symbol Substitution Tests (DSST) to assess their relation with spatial memory.ResultsDVA values in horizontal (H-DVA), vertical (V-DVA), and sagittal (S-DVA) planes ranged from (−0.26) to 0.36 logMAR, (−0.20) to 0.36 logMAR, and (−0.28) to 0.33 logMAR, respectively. The latency of three planes of DVA was affected by vMWMT (Horizontal, Vertical, and Sagittal; Estimate: 22.733, 18.787, 13.341, respectively p < 0.001). Moreover, a moderately significant correlation was also found, with a value of 0.571 between the Virtual MWM test and BFRT and a value of 0.539 between the DSST (p < 0.001).ConclusionSpatial abilities in healthy adults were significantly influenced by dynamic visual functions across horizontal, vertical, and sagittal planes. These findings are expected to trigger essential discussions about the mechanisms that connect the vestibular-visual system to the hippocampus. The original vMWMT protocol is likely to serve as a model for future studies utilizing this technology.

空间记忆与学习：研究动态视觉敏锐度的作用

引言通过虚拟莫里斯水迷宫任务（vMWMT），可以明确前庭系统对空间学习和记忆能力的贡献。这一点非常重要，因为前庭系统与海马区之间存在联系。然而，关于前庭系统在空间能力发展中的作用一直存在争议。本研究旨在评估三个平面上的动态视敏度（DVA）与空间能力之间的关系。方法这项横断面研究的对象是 50 名 18 至 55 岁的健康成年人，他们的压力水平和精神健康状况正常，没有神经、听觉或前庭方面的不适。研究人员进行了用于评估执行功能的 "创迹测试（TMT）表格 A "和 "表格 B"、用于评估视觉运动功能的 "DVA 测试套件 "以及用于评估空间学习和空间记忆的 "虚拟莫里斯水迷宫测试（vMWMT）"。结果水平面（H-DVA）、垂直面（V-DVA）和矢状面（S-DVA）的DVA值分别为（-0.26）至0.36 logMAR、（-0.20）至0.36 logMAR和（-0.28）至0.33 logMAR。DVA 三个平面的潜伏期受到 vMWMT 的影响（水平、垂直和矢状；估计值：分别为 22.733、18.787 和 13.341，p &p;lt;0.001）。结论健康成年人的空间能力受到水平、垂直和矢状平面动态视觉功能的显著影响。这些发现有望引发有关前庭视觉系统与海马体之间联系机制的重要讨论。最初的 vMWMT 方案很可能成为未来利用该技术进行研究的典范。
