现代认知神经科学研究的主要目的是了解认知功能的神经机制,采用神经成像和无创性方法对盲人大脑皮质的实验,证实了盲人的枕叶皮质在盲文阅读时显著激活;经常进行盲文阅读的盲人手指有更大范围躯体感觉皮质表征;追踪空间触觉信息在皮质之间的加工轨迹的实验证明,皮质之间功能连通性有助于解释躯体感觉皮质-视皮质之间跨模块可塑性的神经机制。研究结果为我们提供了独特的机会来了解大脑皮层可塑性和行为补偿可能性的发生发展过程,并可能对重建某些丧失的功能和形成合适的教育策略提供有价值的参考。
The main purpose of modern cognitive neuroscience research is to understand the neural mechanisms of cognitive function. Experiments with neuronal imaging and noninvasive methods on the cerebral cortex of the blind demonstrate that the blind occipital cortex is significantly activated during Braille reading; Of the blind fingers have a wider range of somatosensory cortical features; experiments that track the processing trajectories of spatial haptic information between the cortices demonstrate that the functional connectivity between the cortex helps to explain the somatosensory cortical-transmural plasticity of nerves mechanism. The findings provide us with a unique opportunity to understand the development and progression of the possibilities of cerebral cortical plasticity and behavior compensation and may provide valuable insights into the rebuilding of some of the lost functions and the development of appropriate educational strategies.
