提出并研究了一种伪神经元硬件器件--动态自电光效应器件（DSEED）。首先，从理论上预测了它的类神经元脉冲振荡（（i）快速尖峰型，（ii）阈值尖峰型），并利用计算机实验讨论了它们的振荡特性。其次，研究了它们的扩散耦合网络的点火（脉冲）模式动力学，计算机实验表明，网络中远局域场之间存在三种点火动力学：（a）瞬态混沌点火状态，（B）完全同步（相干）点火状态，（c）部分同步点火状态。特别是，情况（c）表明，放电模式非常类似于在大脑中观察到的远局部场之间的神经同步现象。因此，本装置及其网络如果成功地以硬件实现，则对于验证和开发神经（耦合振荡器）网络的理论以基于非线性动力学的观点考虑或理解脑功能的机制是非常有用的。
A pseudo-neuron hardware device calleddynamicself-electroopticeffectdevice (DSEED) is proposed and considered. First, its neuron-like pulsed oscillations ((i) fast spiking type, (ii) threshold spiking type) are theoretically predicted, and their oscillating properties are discussed using computer experiments. Second, firing (pulsing) pattern dynamics of their diffusion-coupled networks are considered, and the computer experiments indicate that there are three kinds of firing dynamics, (a) transient chaotic firing state, (b) entirely synchronized (coherent) firing state, and (c) partly synchronized firing state, between far local fields in the network. In particular, the case (c) shows that the firing patterns are quite similar to neural synchronization phenomena between far local fields as observed in the brain. So, the present device and their networks are, if successfully realized in hardware, quite useful to verify and develop theories of neural (coupled oscillator) networks to consider or to understand the mechanisms of brain functions based on the viewpoint of nonlinear dynamics.
