Periodically forced piecewise-Linear Adaptive exponential Integrate-and-Fire Neuron
Although variability is a ubiquitous characteristic of the nervous system, under appropriate conditions neurons can generate precisely timed action potentials. Thus considerable attention has been given to the study of a neuron’s output in relation to its stimulus. In this study, we consider an increasingly popular spiking neuron model, the adaptive exponential integrateand-fire neuron. For ana...
متن کاملA mean-field model for conductance-based networks of adaptive exponential integrate-and-fire neurons
Voltage-sensitive dye imaging (VSDi) has revealed fundamental properties of neocortical processing at mesoscopic scales. Since VSDi signals report the average membrane potential, it seems natural to use a mean-field formalism to model such signals. Here, we investigate a mean-field model of networks of Adaptive Exponential (AdEx) integrate-and-fire neurons, with conductance-based synaptic inter...
متن کاملA VLSI Implementation of the Adaptive Exponential Integrate-and-Fire Neuron Model
We describe an accelerated hardware neuron being capable of emulating the adaptive exponential integrate-and-fire neuron model. Firing patterns of the membrane stimulated by a step current are analyzed in transistor level simulations and in silicon on a prototype chip. The neuron is destined to be the hardware neuron of a highly integrated wafer-scale system reaching out for new computational p...

متن کاملTitle : Adaptive exponential integrate - and - fire model as an effective description of neuronal activity
We introduce a two-dimensional integrate-and-fire model which combines an exponential spike mechanism with an adaptation equation, based on recent theoretical findings. We describe a systematic method to estimate its parameters with simple electrophysiological protocols (current-clamp injection of pulses and ramps), and apply it to a detailed conductance-based model of a regular spiking neuron....
