我们提出了一种新颖的实验范式的结果，以研究刺激的空间相关性对电感觉神经网络动力学的影响。此外，提出了一种新的理论分析，用于具有延迟反馈的随机泄漏积分和激发神经元模型网络的动力学。该系统的实验和理论都证实，空间相关性会引起网络振荡，其强度与总刺激功率恒定时的刺激相关性程度成正比。
We present results from a novel experimental paradigm to investigate the influence of spatial correlations of stimuli on electrosensory neural network dynamics. Further, a new theoretical analysis for the dynamics of a model network of stochastic leaky integrate-and-fire neurons with delayed feedback is proposed. Experiment and theory for this system both establish that spatial correlations induce a network oscillation, the strength of which is proportional to the degree of stimulus correlation at constant total stimulus power.
