Spike Response
1. The Spike Response Model 1 ABSTRACT A description of neuronal activity on the level of ion channels, as in the Hodgkin-Huxley model, leads to a set of coupled nonlinear diier-ential equations which are diicult to analyze. In this paper, we present a conceptual framework for a reduction of the nonlinear spike dynamics to a threshold process. Spikes occur if the membrane potential u(t) reaches...
متن کاملEfficient Spike-Coding with Multiplicative Adaptation in a Spike Response Model
Neural adaptation underlies the ability of neurons to maximize encoded information over a wide dynamic range of input stimuli. Recent spiking neuron models like the adaptive Spike Response Model implement adaptation as additive fixed-size fast spike-triggered threshold dynamics and slow spike-triggered currents. Such adaptation accurately models neural spiking behavior over a limited dynamic in...
متن کاملThe Spike Response Model: A Framework to Predict Neuronal Spike Trains
We propose a simple method to map a generic threshold model, namely the Spike Response Model, to artificial data of neuronal activity using a minimal amount of a priori information. Here, data are generated by a detailed mathematical model of neuronal activity. The model neuron is driven with in-vivo-like current injected, and we test to which extent it is possible to predict the spike train of...
متن کاملSpike Response Fitting and Prediction of a Single Neuron Model
Conductance based detail biological models of neurons are able to predict various forms of spiking patterns with great accuracy, but the computational resources required to simulate large network of such neurons are still incomprehensible. As an alternative various simplified spiking models of neurons have been proposed. These models achieve computational efficiency through dynamical system tec...
متن کاملResponse Features Determining Spike Times
Interpreting messages encoded in single neuronal responses requires knowing which features of the responses carry information. That the number of spikes is an important part of the code has long been obvious. In recent years, it has been shown that modulation of the firing rate with about 25 ms precision carries information that is not available from the total number of spikes across the whole ...
