Summary: Delay has a significant impact on the dynamics of neural networks, making it a hot topic in mathematics and engineering. This paper presents a new fractional-order 4D neural network model with two different time delays based on previous research. The existence, uniqueness, and boundedness of the solution are analyzed using contraction mapping principle and the construction of an adaptive function. The stability and emergence of Hopf bifurcation are explored using the stability and bifurcation theory of fractional-order dynamical system. Novel stability criteria and bifurcation conditions are established for different delay cases. The impact of delay on stabilizing neural networks and controlling the emergence of Hopf bifurcation is thoroughly investigated, and Matlab simulations confirm the scientific validity of the derived conclusions.
