In-phase and anti-phase synchronization in noisy Hodgkin-Huxley neurons

The role of intrinsic noise on the spiking of two delay-coupled neurons is studied. ► Characteristic stochastic synchronization patterns are observed. ► The delay-coupling and intrinsic noise result in a locking of the spiking rate. ► The dynamics of the coupled neurons exhibit noise-induced phase-flip bifurcations.
