The spatiotemporal dynamics of the FitzHugh\u2013Rinzel model with time delay and diffusion in a random network are investigated in this paper. The conditions for Turing instability and Hopf bifurcation are obtained by linear stability analysis. It is found that the stability of the system changes with the time delay. Then the critical time delay for the state transition of the system is derived. Moreover, it is shown that Turing pattern is related to the network diffusion and connection probability. The increase of the diffusion coefficient will change the spatiotemporal pattern of the system. In addition, the system will achieve firing synchronization as the connection probability increases. Finally, numerical simulation verifies the theoretical results. <\/jats:p>","DOI":"10.1142\/s0218127423501675","type":"journal-article","created":{"date-parts":[[2023,11,24]],"date-time":"2023-11-24T02:56:42Z","timestamp":1700794602000},"source":"Crossref","is-referenced-by-count":3,"title":["Stability and Bifurcation Analyses of the FitzHugh\u2013Rinzel Model with Time Delay in a Random Network"],"prefix":"10.1142","volume":"33","author":[{"given":"Dan","family":"Yi","sequence":"first","affiliation":[{"name":"School of Mathematics and Statistics, Fujian Normal University, Fuzhou 350117, P.
