Metaplasticity, a higher order of synaptic plasticity, as well as a key issue in neuroscience, is realized with artificial synapses based on a WO3 thin film, and the activity-dependent metaplastic responses of the artificial synapses, such as spike-timing-dependent plasticity, are systematically investigated. This work has significant implications in neuromorphic computation.
形质转换，一种更高阶的突触可塑性，也是神经科学的关键问题，是通过基于 WO3 薄膜的人工突触来实现的，并且系统地研究了人工突触的活动依赖性形质转换响应，如尖峰时间依赖可塑性。这项工作在神经形态计算中有重要意义。
