Subject: Re: auditory stochastic resonance demos?

The effect differs from the classical amplitude-based effect. These neurons and models are slope or ramp-detectors. Noise can enable them to respond to slopes that too slow for them to notice in the absence of noise. We call the phenomenon: slope-based stochastic resonance. So far we don't have a behavioral demonstration. Gai Y, Doiron B, Kotak V, Rinzel J: Noise-gated encoding of slow inputs by auditory brainstem neurons with a low-threshold K+ current.
