The neural substrate of the plastic change in tactile stimulation.

我们检查了一项fMRI研究，以阐明长期训练中神经基质的可塑性变化。当参与者对实验刺激进行触觉辨别时，受过良好训练的受试者的V1被激活。在对照组（未接受过刺激）受试者中，V1未被激活。目前，我们正在对所获得的数据进行分析，以揭示实验组之间在几个脑区的连通性、脑区的体积和神经纤维束方面的神经基质的差异和机制。

We examined an fMRI study to clarify the plastic change of neural substrate in long term training. When participants performed tactile discrimination of experimental stimuli, the V1 were activated in the well-trained subjects. In the control (stimuli naive) subjects, the V1 was not activated. Now we are analyzing the obtained data to reveal the mechanisms and difference of neural substrate between experimental groups about the connectivity of several brain regions, the volumes of brain areas and the neuronal fiber tract.
