The application of external electromagnetic stimulation to regulate the electrophysiological activities of specific brain regions can provide an ideal control or treatment scheme for some non-organic mental diseases. To further explore the effectiveness of electromagnetic stimulation in the treatment of mental illnesses, the regulatory abilities of external electromagnetic stimulation on the pattern dynamics of Newman–Watts small-world neuronal networks are systematically studied. The main stability function is used to construct four periodic or chaotic synchronous networks. Also, the average discharge frequency and the consistency coefficient are selected to measure the regulatory effects of external electromagnetic stimulation on the network dynamics. Numerical experiments show that electromagnetic stimulation can inhibit the electrophysiological activities of neuronal networks. Periodic electromagnetic stimulation with large amplitude or stochastic electromagnetic stimulation with large deviation has a more significant inhibitory effect on the discharge activities, not only effectively desynchronizing the discharge activities, but also controlling the evolution of spatiotemporal patterns, and even inducing the synchronization transition. Additionally, the number of stimulated neurons in neuronal networks also plays an important role in the evolution of spatiotemporal patterns. This study could provide theoretical guidance for the physiological application of electromagnetic stimulation in the treatment of certain mental diseases.

神经网络外部电磁刺激的模式控制

应用外部电磁刺激调节特定大脑区域的电生理活动可以为某些非器官性精神疾病提供理想的控制或治疗方案。为了进一步探索电磁刺激在治疗精神疾病中的有效性,系统地研究了外部电磁刺激对纽曼-瓦特小世界神经元网络模式动态的调节能力。主要稳定性函数用于构造四个周期或混沌同步网络。同样,选择平均放电频率和一致性系数以测量外部电磁刺激对网络动力学的调节作用。数值实验表明,电磁刺激可以抑制神经网络的电生理活动。具有大幅度的周期性电磁刺激或具有大偏差的随机电磁刺激对放电活动具有更显着的抑制作用,不仅有效地使放电活动去同步,而且还控制时空模式的演变,甚至诱发同步转变。另外,神经元网络中受激神经元的数量在时空模式的演变中也起着重要作用。该研究可为电磁刺激在某些精神疾病治疗中的生理应用提供理论指导。具有大幅度的周期性电磁刺激或具有大偏差的随机电磁刺激对放电活动具有更显着的抑制作用,不仅有效地使放电活动去同步,而且还控制时空模式的演变,甚至诱发同步转变。另外,神经元网络中受激神经元的数量在时空模式的演变中也起着重要作用。该研究可为电磁刺激在某些精神疾病治疗中的生理应用提供理论指导。具有大幅度的周期性电磁刺激或具有大偏差的随机电磁刺激对放电活动具有更显着的抑制作用,不仅有效地使放电活动失步,而且还控制了时空模式的演变,甚至诱发了同步跃迁。另外,神经元网络中受激神经元的数量在时空模式的演变中也起着重要作用。该研究可为电磁刺激在某些精神疾病治疗中的生理应用提供理论指导。不仅有效地使放电活动不同步,而且还控制时空模式的演变,甚至诱发同步转变。另外,神经元网络中受激神经元的数量在时空模式的演变中也起着重要作用。该研究可为电磁刺激在某些精神疾病治疗中的生理应用提供理论指导。不仅有效地使放电活动不同步,而且还控制时空模式的演变,甚至诱发同步转变。另外,神经元网络中受激神经元的数量在时空模式的演变中也起着重要作用。该研究可为电磁刺激在某些精神疾病治疗中的生理应用提供理论指导。
