Output stream of binding neuron with delayed feedback
نویسنده
چکیده
A binding neuron (BN) whith delayed feedback is considered. The neuron is fed externally with a Poisson stream of intensity λ . The neuron’s output spikes are fed into its input with time delay ∆. The resulting output stream of the BN is not Poissonian, and we look for its interspike intervals (ISI) distribution. For BN with threshold 2 an exact mathematical expression as function of λ , ∆ and BN’s internal memory, τ is derived for the ISI distribution, and for higher thresholds it is found numerically. The distributions found are characterized with discontinuities of jump type, and include singularity of Dirac’s δ -function type. It is concluded that delayed feedback presence can radically alter neuronal output firing statistics.

Output Stream of Binding Neuron with Feedback
The binding neuron (BN) output firing statistics is considered. The neuron is driven externally by the Poisson stream of intensity l . The influence of the feedback, which conveys every output impulse to the input with time delay ∆ ≥ 0 , on the statistics of BN’s output spikes is considered. The resulting output stream is not Poissonian, and we look for its interspike intervals (ISI) distributi...
متن کاملFiring statistics of inhibitory neuron with delayed feedback. I. Output ISI probability density
Activity of inhibitory neuron with delayed feedback is considered in the framework of point stochastic processes. The neuron receives excitatory input impulses from a Poisson stream, and inhibitory impulses from the feedback line with a delay. We investigate here, how does the presence of inhibitory feedback affect the output firing statistics. Using binding neuron (BN) as a model, we derive an...
متن کاملActivity of any neuron with delayed feedback stimulated with Poisson stream is non-Markov
For a class of excitatory spiking neuron models with delayed feedback fed with a Poisson stochastic process, it is proven that the stream of output interspike intervals cannot be presented as a Markov process of any order.
متن کاملRelation between firing statistics of spiking neuron with delayed fast inhibitory feedback and without feedback
We consider a class of spiking neuronal models, defined by a set of conditions typical for basic threshold-type models, such as the leaky integrate-and-fire or the binding neuron model and also for some artificial neurons. A neuron is fed with a Poisson process. Each output impulse is applied to the neuron itself after a finite delay ∆. This impulse acts as being delivered through a fast Cl-typ...
