在生物神经系统中，相互作用的神经元的运作在很大程度上依赖于星形胶质细胞的调节。受这一生物学现象的启发，提出了具有星形胶质细胞样控制的刺激性神经P系统，即SN P系统，并被证明具有“图灵完备性”作为计算模型。在这项工作中，研究了这种系统在创建逻辑运算符方面的应用。具体地说，构造性地得到了具有星形细胞控制的SN P系统可以综合布尔逻辑门，即AND、OR、NOT、NOR、XOR和NAND门的运算。由此产生的系统简单而同质，这意味着只使用一种具有独特尖峰规则的神经元。利用这些类神经逻辑门，可以构造更复杂的级联布尔电路。因此，它们可用于实现有限计算设备，例如有限换能器。这些结果展示了一种构造以类神经方式工作的逻辑电路的新方法，并为神经电路设计的潜在方向提供了一些理论上的启发。(C)2016 Elsevier Inc.保留所有权利。
In biological nervous systems, the operation of interacting neurons depends largely on the regulation from astrocytes. Inspired by this biological phenomenon, spiking neural P systems, i.e. SN P systems, with astrocyte-like control were proposed and were proven to have "Turing completeness" as computing models. In this work, the application of such systems for creating logical operators is investigated. Specifically, it is obtained in a constructive way that SN P systems with astrocyte-like control can synthesize the operations of Boolean logic gates, i.e. AND, OR, NOT, NOR, XOR and NAND gates. The resulting systems are simple and homogeneous, which means only one type of neuron with a unique spiking rule is used. With these neural-like logic gates, more complex Boolean circuits with cascade connections can be constructed. As such, they can be used to implement finite computing devices, such as the finite transducers. These results demonstrate a novel method of constructing logic circuits that work in a neural-like manner, as well as, shed some lights on potential directions of designing neural circuits theoretically.
