Contradictory to the intuitive belief, noise has constructive effects on the dynamical processes in nonlinear systems. In this paper, we investigated the effects of the frequency of stimuli, which is introduced to the one of the neuron that acts as a pacemaker and the information transmission delay on the stochastic resonance phenomena depends on channel noise in scale-free Hodgkin-Huxley (HH) neuronal networks. The obtained results reveal that irrespective of the placing of the pacemaker within the network there exists several frequencies at which the correlation between the rhythm of pacemaker and the response of the network resonantly depends on channel noise intensity. The results also demonstrated that proper values of delays can trigger stochastic multiresonances occurring that at every multiple of the pacemaker's oscillation period.
