Abstract:
Historically, cross-modal plasticity following early blindness has been largely studied in the context of visual deprivation. However, more recently, there has been a shift in focus towards understanding cross-modal plasticity from the perspective of skill acquisition: the striking plasticity observed in early blind individuals reflects the extraordinary perceptual and cognitive challenges they solve. Here, inspired by two seminal papers on skill learning (the \"cortical recycling\" theory) and cross-modal plasticity (the \"metamodal\" hypothesis) respectively, we present a unified hypothesis of cortical specialization that describes how shared functional, algorithmic, and structural constraints might mediate both types of plasticity.
摘要:
历史上,在视觉剥夺的背景下,对早期失明后的跨模态可塑性进行了大量研究。然而,最近,从技能获取的角度来看,人们的关注点已经转移到了理解跨模式可塑性的方向:在早期盲人中观察到的惊人可塑性反映了他们解决的非凡的感知和认知挑战。这里,分别受到两篇关于技能学习(“皮质循环”理论)和跨模态可塑性(“元模态”假设)的开创性论文的启发,我们提出了一个大脑皮层特化的统一假设,描述了共享功能,算法,结构约束可能会调解这两种类型的可塑性。
