手脸边界是灵长类体感皮层最显着的特征之一。截肢或麻醉后体感输入的减少会引起跨越该边界的知觉变化，这可以通过可塑性竞争机制来解释[1-4]。依赖于增加体感输入的学习过程是否可以诱导跨境可塑性尚不清楚。在这里，我们报告说，独立于训练的学习 [5] 不仅改善了受刺激的食指的触觉感知，而且还改善了未受刺激的面部的触觉感知。这些发现表明，学习引起的触觉改善可以跨越手脸边界，这表明基于促进的可塑性可能在健康的人脑中发挥作用。
The hand–face border is one of the most prominent features of the primate somatosensory cortex. A reduction of somatosensory input, following amputation or anesthesia, induces perceptual changes across this border that are explained by plastic competitive mechanisms [1–4]. Whether cross-border plasticity can be induced by learning processes relying on increased somatosensory input has been unclear. Here we report that training-independent learning [5] improves tactile perception, not only at the stimulated index finger, but also at the unstimulated face. These findings demonstrate that learning-induced tactile improvement can cross the hand–face border, suggesting that facilitation-based plasticity may operate in the healthy human brain.
