Abstract：
The possibility to induce a transient modulation of visuo-spatial attention boosted so far the implementation of the prism adaptation in a variety of domains. This sensorimotor technique has been adopted to investigate the neural plasticity in neurologically healthy individuals, as well as to ameliorate deficit of visuo-spatial attention (which characterizes neglect patients\' performance). We review here evidence about a new promising application of prisms in exploring how the human brain represents the subjective time flow on a spatially oriented \"mental time line\". Converging observations in healthy individuals suggest that altering spatial attention processing via prism adaptation can influence the spatial representation of time. These modulatory effects are generalizable to different aspects of time, such as the abilities to estimate time duration and to mentally travel in time. Furthermore, data from brain damaged patients, with a special focus on right brain-damaged patients with neglect, indicate that prismatic procedure ameliorates temporal deficits, hence paving the way to novel clinical applications. We conclude by discussing the possible cognitive mechanisms and neural circuits of the prism adaptation effects on time.
摘要：
到目前为止，引起视觉空间注意力瞬态调制的可能性促进了棱镜自适应在多个领域中的实现。这种感觉运动技术已被用来研究神经健康个体的神经可塑性，以及改善视觉空间注意力的缺陷(这是忽视患者表现的特征)。我们在此回顾有关棱镜在探索人脑如何在空间定向的“心理时间线”上代表主观时间流方面的新应用的证据。在健康个体中聚集的观察表明，通过棱镜适应改变空间注意力处理可以影响时间的空间表示。这些调节作用可以推广到时间的不同方面，例如估计持续时间和精神旅行的能力。此外，来自脑损伤患者的数据，特别关注忽视右脑受损患者，表明棱柱术改善了颞部缺陷，从而为新的临床应用铺平了道路。最后，我们讨论了棱镜适应对时间影响的可能认知机制和神经回路。
