A four-dimensional neural network model with delay is investigated. With the helpof the theory of delay differential equation and Hopf bifurcation, the conditions of the equilibriumundergoing Hopf bifurcation are worked out by choosing the delay as parameter. Applying thenormal form theory and the center manifold argument, we derive the explicit formulae fordetermining the properties of the bifurcating periodic solutions. Numerical simulations areperformed to illustrate the analytical results
