这篇综述的重点是视觉剥夺导致的跨模式可塑性。这是在特定任务的视觉皮层募集的背景下看待的，这种募集在有视力的触觉任务中是常规的，并且可能部分取决于视觉图像。盲人卓越的触觉感知表现可能与实践有关，尽管有关盲文阅读体验的影响和失明发病年龄的问题尚未解决。虽然盲人的视觉皮层区域显然比视力正常的人更多地参与触觉微空间处理，但仍然不清楚如何将这些触觉过程与越来越多的文献相协调，这些文献暗示盲人的视觉皮层活动涉及盲人的广泛认知任务，包括涉及语言的任务，或者与正常视力者的短期、可逆视觉剥夺的研究相一致，这些研究揭示了甚至在数小时或数天内的可塑性变化。
This review focusses on cross-modal plasticity resulting from visual deprivation. This is viewed against the background of task-specific visual cortical recruitment that is routine during tactile tasks in the sighted and that may depend in part on visual imagery. Superior tactile perceptual performance in the blind may be practice-related, although there are unresolved questions regarding the effects of Braille-reading experience and the age of onset of blindness. While visual cortical areas are clearly more involved in tactile microspatial processing in the blind than in the sighted, it still remains unclear how to reconcile these tactile processes with the growing literature implicating visual cortical activity in a wide range of cognitive tasks in the blind, including those involving language, or with studies of short-term, reversible visual deprivation in the normally sighted that reveal plastic changes even over periods of hours or days.
