Photosensitive neurons can capture and convert external optical signals, and then realize the encoding signal. It is confirmed that a variety of firing modes could be induced under optical stimuli. As a result, it is interesting to explore the mode transitions of collective dynamics in the photosensitive neuron network under external stimuli. In this work, the collective dynamics of photosensitive neurons in a small-world network with non-synaptic coupling will be discussed with spatial diversity of noise and uniform noise applied on, respectively. The results prove that a variety of different collective electrical activities could be induced under different conditions. Under spatial diversity of noise applied on, a chimera state could be observed in the evolution, and steady cluster synchronization could be detected in the end; even the nodes in each cluster depend on the degree of each node. Under uniform noise applied on, the complete synchronization window could be observed alternately in the transient process, and steady complete synchronization could be detected finally. The potential mechanism is that continuous energy is pumped in the phototubes, and energy exchange and balance between neurons to form the resonance synchronization in the network with different noise applied on. Furthermore, it is confirmed that the evolution of collective dynamical behaviors in the network depends on the external stimuli on each node. Moreover, the bifurcation analysis for the single neuron model is calculated, and the results confirm that the electrical activities of single neuron are sensitive to different kinds of noise.

光敏神经元可以捕获并转换外部光信号，进而实现编码信号。已证实在光刺激下可以诱导多种发射模式。因此，探索外部刺激下光敏神经网络中集体动力学的模式转变是很有趣的。在这项工作中，将分别在应用噪声的空间多样性和均匀噪声的情况下讨论非突触耦合的小世界网络中光敏神经元的集体动力学。结果证明，在不同条件下可以诱发多种不同的集体电活动。在施加噪声的空间多样性的情况下，在演化过程中可以观察到嵌合状态，最终可以检测到稳定的簇同步；甚至每个簇中的节点也取决于每个节点的度。在施加均匀噪声的情况下，在瞬态过程中可以交替观察到完全同步窗口，最终可以检测到稳定的完全同步。其潜在机制是光电管中连续泵入能量，神经元之间进行能量交换和平衡，在施加不同噪声的情况下形成网络中的共振同步。此外，还证实网络中集体动态行为的演化取决于每个节点的外部刺激。此外，还计算了单神经元模型的分岔分析，结果证实了单神经元的电活动对不同种类的噪声敏感。
