This paper addresses a bifurcation analysis of a neutral fractional-order neural network (NFONN) with neutral-type delays on the basis of reducing the degree of transcendental terms with respect to the characteristic equation. The delay-dependent bifurcation results are deduced by analyzing the characteristic equation. Furthermore, some worthwhile phenomena are observed: On the one hand, the developed NFONN possesses illustrious stability performance in comparison with the corresponding integer-order NN. On the other hand, the shorter convergence time of the devised NFONN can be captured by selecting appropriate parameters compared with the traditional delayed NN. The developed approach involves the superiorities with direct operation process, low computational complexity and easy implementation in comparison with some approaches available. Lastly, two numerical examples are adopted to underpin the developed theoretical outcomes.
