Paper Abstract
The phenomenon of noise enhanced signal transfer, or stochastic
resonance, has been observed in many nonlinear systems such as
neurons and ion channels. Initial studies of stochastic resonance
focused on systems driven by a periodic signal, and hence used a
signal to noise ratio based measure for comparison between the
input and output of the system. It has been pointed out that for
the more general case of aperiodic signals other measures are
required, such as cross-correlation or information theoretical
tools. In this paper we present simulation results obtained in a
model neural system driven by a broadband aperiodic signal, and
producing a signal imitating neural spikes. The system is analyzed
by using cross-spectral measures.
