The dynamics of spiking and bursting activities have attracted interest from scientists due to their significance in the brain and neural systems. In this work, the effects of processing delay, specifically the time delay in coupling, on the dynamical behaviors of the coupled Hindmarsh–Rose neurons with resting state are investigated. The results reveal that the processing delay can induce rich spiking patterns, such as anti-phase synchronous spiking, in-phase synchronous periodic bursting, anti-phase synchronous periodic bursting and anti-phase synchronous chaotic bursting, and maintained the bistability and tristability of different spiking patterns. This emphasizes that the processing delay-induced spiking patterns might not be observed in the diffusively coupled neurons with resting state with and without propagation delay. The results can help deepen the knowledge on neural synchronization and information processing in the neuronal network and brain.

尖峰和爆发活动的动力学因其在大脑和神经系统中的重要性而吸引了科学家的兴趣。在这项工作中，研究了处理延迟（特别是耦合中的时间延迟）对具有静止状态的耦合Hindmarsh-Rose神经元动力学行为的影响。结果表明，处理延迟可以引起丰富的尖峰模式，如反相同步尖峰，同相同步周期突发，反相同步周期突发和反相同步混沌突发，并保持了不同的双稳态和三稳性。尖刺的图案。这强调了在具有或不具有传播延迟的静止状态的扩散耦合神经元中可能未观察到处理延迟引起的尖峰模式。
