成年人的大脑能否将一种新颖的、地形学上组织的感觉形态同化到它的知觉库中？为了测试这一点，我们实现了一个基于微刺激的神经假体，大鼠用来区分红外（IR）光源。该系统连续地将来自四个IR传感器的信息传递到初级躯体感觉皮层（S1），所述IR传感器被分布以提供IR源的全景。老鼠学会了辨别红外线源的位置，
Can the adult brain assimilate a novel, topographically organized, sensory modality into its perceptual repertoire? To test this, we implemented a microstimulation-based neuroprosthesis that rats used to discriminate among infrared (IR) light sources. This system continuously relayed information from four IR sensors that were distributed to provide a panoramic view of IR sources, into primary somatosensory cortex (S1). Rats learned to discriminate the location of IR sources in
