Responses of a Noisy Hodgkin-Huzley Neuron Model with Suprathreshold Superimposed Forcing
The mammalian auditory cortex can respond to the signals of different tone frequencies. Accordingly, we investigated the firing activity of a Hodgkin-Huxley neuron model which was forced by a suprathreshold superimposed sinusoidal signal in the presence of noise. The results showed that there was suprathreshold stochastic resonance. In addition, the neuron model behaved optimally to the different frequency components of the superimposed signal at different noise intensities and was sensitive with different frequencies with the increasing of noise intensity. This study may help to disclose the signal processing in the neural system, especially the auditory system, and be of a functional significance to signal processing.
