Stochastic resonance in neuron models: endogenous stimulation revisited.
The paradigm of stochastic resonance (SR)-the idea that signal detection and transmission may benefit from noise-has met with great interest in both physics and the neurosciences. We investigate here the consequences of reducing the dynamics of a periodically driven neuron to a renewal process (stimulation with reset or endogenous stimulation). This greatly simplifies the mathematical analysis,...
متن کاملStochastic Resonance in Thalamic Neurons and Resonant Neuron Models
Neurons of the thalamus are major participants in gating sensory information for relay to the neocortex. Thalamic neurons are crucially involved in rhythmogenesis which determines the sleep/wake cycle. These roles require critical involvement of a T-type calcium current, conferring a frequency preference in response to subthreshold signals. We examine the interactions of this membrane resonance...
متن کاملStochastic resonance in noisy spiking retinal and sensory neuron models
Two new theorems show that small amounts of additive white noise can improve the bit count or mutual information of several popular models of spiking retinal neurons and spiking sensory neurons. The first theorem gives necessary and sufficient conditions for this noise benefit or stochastic resonance (SR) effect for subthreshold signals in a standard family of Poisson spiking models of retinal ...
متن کاملExtending Stochastic Resonance for Neuron Models to General Lévy Noise
A recent paper by Patel and Kosko (2008) demonstrated stochastic resonance (SR) for general feedback continuous and spiking neuron models using additive Lévy noise constrained to have finite second moments. In this brief, we drop this constraint and show that their result extends to general LEvy noise models. We achieve this by showing that "large jump" discontinuities in the noise can be contr...
متن کاملGhost Stochastic Resonance for a Stochastic Single Neuron Model
The response of a neuron to a linear combination of the first two harmonics of a fundamental frequency is studied by means of a leaky integrate and fire model. A suitable modification of the classical stochastic model is introduced to consider such input. The resulting interspike interval distribution exhibits maxima in correspondence with the fundamental frequency that was absent in the input ...
