A two-neuron network with self/neighbour-delayed-connections has been investigated. The self-connections are proposed by excitatory synapses and the neighbour ones by excitatory and inhibitory synapses. It is found that the excitatory self-connections can lead to non-resonant double Hopf bifurcations, for example, 1:√2 double Hopf bifurcation, since the double Hopf bifurcation disappears without self-delayed connections. Various dynamic behaviours are classified in the neighbourhood of the double Hopf bifurcation point, and the bifurcating solutions are computed in an approximate form by the centre manifold reduction. It follows from the approximate solutions that the network of two identical neurons with neighbour-connection cannot be synchronized completely. However, generalized synchronization can occur in the network under consideration. The time delay can also lead to the disappearance of periodic motion. These results may have some potential applications, such as controlling associative memory and designing neural networks. |
