چکیده
The effective noise intensity D that is used to evaluate theoretical value of 〈C1〉 throughout the original paper is inaccurate. In Sec. III A, we derived the piecewise-linear FitzHugh-Nagumo (plFHN) neuron model, and we introduced the noise scaling ξ (t) → 7τξ (t̃) in correspondence with the time scaling t → 7τ t̃ . However, the noise should be scaled as ξ (t) → √7τξ (t̃). Therefore, the plFHN neuron mode I in Eq. (6) and (A1) should read

Growth of stochastic resonance in neuronal ensembles with the input signal intensity.
The presence of noise can improve the response of certain nonlinear systems to input signals through the effects of stochastic resonance (SR). The optimal noise intensity for SR is proportional to the signal frequency if the signal is periodic, but proportional to the signal intensity if the signal is aperiodic. Here, we demonstrate using linear response theory that the optimal noise intensity ...
متن کاملAperiodic stochastic resonance.
Stochastic resonance ~SR! is a phenomenon wherein the response of a nonlinear system to a weak periodic input signal is optimized by the presence of a particular level of noise. Recently, we presented a method and theory for characterizing SR-type behavior in excitable systems with aperiodic ~i.e., broadband! input signals @Phys. Rev. E 52, R3321~1995!#. We coined the term aperiodic stochastic ...

Introduction: Diffusion Weighted Magnetic Resonance Imaging (DWMRI) provides visual contrast, depends on Brownian motion of water molecules. The diffusive behavior of water in cells alters in many disease states. Dephasing is a factor of magnetic field inhomogeneity, heterogeneity of tissue and etc., which is associated with the signal amplitude. In a series of DWI acquisition...
متن کاملStochastic resonance in models of neuronal ensembles
Two recently suggested mechanisms for the neuronal encoding of sensory information involving the effect of stochastic resonance with aperiodic time-varying inputs are considered. It is shown, using theoretical arguments and numerical simulations, that the nonmonotonic behavior with increasing noise of the correlation measures used for the so-called aperiodic stochastic resonance ~ASR! scenario ...
