法国巴黎de la 视觉研究所的Sanda 等近日在Brain Struct Funct发表了一项新的工作,他们探讨了中央或周边神经视力丧失后的皮质的变化情况。

特异影响中枢和周围视觉的疾病对研究人类大脑如何适应视觉异常是十分重要的模型。在12名Stargardt黄斑营养不良、12名色素性视网膜炎(隧道视力阶段)和14名正常视力受试者中进行分析,获取皮质厚度(CoTks)和静息状态皮层熵(rs-CoEn)等数据作为神经和突触复杂性的指标。

与对照组相比,两组视力丧失的患者在背部V3d区域显示出CoTks减少。周边视野损失表现出特定的CoTks在早期视觉皮层和腹侧区域V4中减少,而中枢视野丧失则引起背侧区域V3A的减少。只有中枢视野丧失后表现出LO-2区和FG1中的CoEn的增加。

因此,他们认为,他们发现了在中央和周边视野缺损之后背侧和腹侧视觉的脑可塑性生物标志物。
