通过身体运动引起的感觉运动经验的皮质学习早在胎儿时期就开始了。然而，由于技术和伦理上的困难，感觉运动经验指导皮层学习的学习机制仍然未知。为了弥补这一差距，我们通过整合解剖学/生理学数据，提出了一个人类胎儿作为脑-体-环境耦合系统的具体大脑模型。利用这个模型，我们展示了与身体运动相关的子宫内感觉运动体验如何在体感反馈中诱发特定的统计规律，从而促进身体表征的皮质学习和随后的视觉-体感整合。我们还展示了子宫外感觉运动体验如何影响这些过程。我们的具身脑模型可以为基于感觉运动经验的皮层学习机制的理解提供一种新的计算方法，这种感觉运动经验是由身体、环境和神经系统之间的复杂相互作用介导的。
Cortical learning via sensorimotor experiences evoked by bodily movements begins as early as the foetal period. However, the learning mechanisms by which sensorimotor experiences guide cortical learning remain unknown owing to technical and ethical difficulties. To bridge this gap, we present an embodied brain model of a human foetus as a coupled brain-body-environment system by integrating anatomical/physiological data. Using this model, we show how intrauterine sensorimotor experiences related to bodily movements induce specific statistical regularities in somatosensory feedback that facilitate cortical learning of body representations and subsequent visual-somatosensory integration. We also show how extrauterine sensorimotor experiences affect these processes. Our embodied brain model can provide a novel computational approach to the mechanistic understanding of cortical learning based on sensorimotor experiences mediated by complex interactions between the body, environment and nervous system.
