Abstract

The paper discusses and provides support for diverse processes of brain plasticity in visual function after damage in infancy and childhood in comparison with injury that occurs in the adult brain. We provide support and description of neuroplastic mechanisms in childhood that do not seemingly exist in the same way in the adult brain. Examples include the ability to foster the development of thalamocortical connectivities that can circumvent the lesion and reach their cortical destination in the occipital cortex as the developing brain is more efficient in building new connections. Supporting this claim is the fact that in those with central visual field defects we can note that the extrastriatal visual connectivities are greater when a lesion occurs earlier in life as opposed to in the neurologically mature adult. The result is a significantly more optimized system of visual and spatial exploration within the 'blind' field of view. The discussion is provided within the context of "blindsight" and the "Sprague Effect".

摘要

本文讨论并支持了婴儿期和儿童期脑损伤后视觉功能中与成人大脑损伤相比不同的脑可塑性过程。我们提供了儿童期神经可塑性机制的支持和描述,而成人大脑中似乎不存在同样的机制。例如,随着发育中的大脑在建立新连接方面更有效率,能够促进丘脑皮质连接的发展,这些连接可以绕过病变并到达枕叶皮质的目标区域。支持这一观点的事实是,在患有中心视野缺损的人中,我们可以注意到,与神经成熟的成年人相比,生命早期发生病变时,纹外视觉连接更强。结果是在“盲”视野内视觉和空间探索系统得到了显著优化。本文在“盲视”和“斯普拉格效应”的背景下进行了讨论。
