This paper is concerned with the intermittent pinning control problem for exponential synchronization of memristor-based neural networks with time-varying delays.By applying nonperiodic intermittent c
生物神经网络的同步在神经信息的处理中具有重要意义。本文在Hodgkin-Huxley(HH)神经元网络模型中考虑树突整合特性，得到修正后的DHH(Dendritic-integration-rule-based HH)神经元网络模型，研究了网络的放电和同步特性。首先以三个抑制性神经元构成的耦合系统为例，我们发现在外部激励达到一定程度时神经元才可以持续进行峰放电。
Activity of neurons in the pre-B(o)tzinger complex(pre-B(o)tC)within the mammalian brainstem has an important role in the generation and regulation of respiratory rhythms.Previous experimental results
The brain neural system is often disturbed by electromagnetic and noise environments,and research on dynamic response of its interaction has received extensive attention.This paper investigates electr
In this paper,statistical complexity measures are employed to quantify the stochastic resonance in a bistable fractional-order system.we investigate the effects of the fractional order of the system,t
It is well known that noise plays an important role in gene regulatory network.in this paper,Our study of stochastic resonances in the coupled gene regulatory system extends to the case of non-Gaussia
尽管近年来脑-机接口技术取得了快速发展,但开发可实用化的系统仍然面临诸多技术挑战[1]。现有的脑-机接口大都是在实验室内构建的验证系统,在刺激呈现、数据解码、存储传输方面均有诸多限制,阻碍了脑-机接口在更多领域的进一步应用。同时,受通道数和信号质量的限制,现有商业化的移动式脑-机接口(如NeuroSky,Emotiv)尚无法构建高性能脑-机接口应用。
癫痫是一种阵发性的脑神经疾病，全球约有6000 万的人口不同程度的受到癫痫所带来的健康影响。而其中大约1/3 的癫痫病例科学家仍然无法完全理解其机理。因此，目前的抗癫痫的治疗很多时候都无法取得期望的疗效。而胶质细胞作为一种最新发现的可能参与癫痫发作的细胞，对于我们更全面的理解癫痫发作机理以及开发新型抗癫痫药物具有重要的意义。
In this paper,a predator-prey system with double Allee effects and time delay is considered.On the one hand,by using time delay as bifurcation parameter,the stability of the interior equilibrium point
AMPA 受体主要存在于兴奋性神经元突触中,负责介导中枢神经系统中大部分的快速兴奋性突触传递,它在突触后膜的动态活动中能够诱发和维持长时程增强(long-term potentiation,LTP)和长时程抑制(long-term depression,LTD)作用,进而影响大脑的学习和记忆活动。因此,研究AMPA 受体的输运机制,有助于研究大脑学习和记忆的生理机制,具有重要的科研和实际意义。实验
