Visual modality dominates spatial perception and, in lack of vision, space representation might be altered. Here we review our work showing that blind individuals have a strong deficit when performing spatial bisection tasks (Gori et al., 2014). We also describe the neural correlates associated with this deficit, as blind individuals do not show the same ERP response mimicking the visual C1 reported in sighted people during spatial bisection (Campus et al., 2019). Interestingly, the deficit is not always evident in late blind individuals, and it is dependent on blindness duration. We report that the deficit disappears when one presents coherent temporal and spatial cues to blind people. This suggests that they may use time information to infer spatial maps (Gori et al., 2018). Finally, we propose a model to explain why blind individuals are impaired in this task, speculating that a lack of vision drives the construction of a multi-sensory cortical network that codes space based on temporal, rather than spatial, coordinates.

失明的空间度量：行为和皮层处理。

视觉形态主导着空间感知，在缺乏视觉的情况下，空间表现形式可能会发生变化。在这里，我们回顾了我们的工作，结果表明，盲人在执行空间二等分任务时具有很大的缺陷（Gori等，2014）。我们还描述了与这一缺陷相关的神经相关因素，因为盲人在空间平分期间没有显示出与视觉C1相似的ERP反应来模仿视觉C1（Campus等人，2019）。有趣的是，赤字在晚期盲人中并不总是很明显，它取决于盲人的持续时间。我们报告说，当人们向盲人呈现连贯的时空线索时，赤字就消失了。这表明他们可能使用时间信息来推断空间图（Gori et al。，2018）。最后，
