在先天盲人的梦中存在视觉意象一直是一个有争议的问题。我们开始系统地审查已发表的关于不同研究领域的先天性和早期失明受试者的视觉空间印象的存在和性质的工作,来自实验心理学,功能神经成像,感官替代,睡眠研究
■使用以下数据库确定了相关研究:EMBASE,MEDLINE和心理信息。
■使用不同成像技术和感觉替代装置的研究表明,“盲人”枕骨皮质可能能够整合非视觉感觉输入,因此也可能产生视觉空间印象。视觉印象也已经由具有濒死或体外经历的盲人受试者报告。
■破译这些视觉印象的机制性质可以为神经可塑性的利用及其治疗神经残疾的潜在作用开辟新的可能性。
UNASSIGNED: The presence of visual imagery in dreams of congenitally blind people has long been a matter of substantial controversy. We set to systematically
review body of published work on the presence and nature of oneiric visuo-spatial impressions in congenitally and early blind subjects across different areas of research, from experimental psychology, functional neuroimaging, sensory substitution, and sleep research.
UNASSIGNED: Relevant studies were identified using the following databases: EMBASE, MEDLINE and PsychINFO.
UNASSIGNED: Studies using diverse imaging techniques and sensory substitution devices broadly suggest that the \"blind\" occipital cortex may be able to integrate non-visual sensory inputs, and thus possibly also generate visuo-spatial impressions. Visual impressions have also been reported by blind subjects who had near-death or out-of-body experiences.
UNASSIGNED: Deciphering the mechanistic nature of these visual impression could open new possibility in utilization of neuroplasticity and its potential role for treatment of neurodisability.
