Interpretation of neuronal response properties with simplified neuron models

Computational neuroscience is a branch of the neurosciences that attempts to elucidate the principles underlying the operation of neurons with the help of mathematical modeling. In contrast with a number of fields pursuing a tightly related goal, such as m ...

Extracting non-linear integrate-and-fire models from experimental data using dynamic I – V curves

Wulfram Gerstner, Laurent Badel, Carl Petersen, Sandrine Lefort, Thomas Berger

The dynamic I–V curve method was recently introduced for the efficient experimental generation of reduced neuron models. The method extracts the response properties of a neuron while it is subject to a naturalistic stimulus that mimics in vivo-like fluctua ...

Dynamic I-V curves are reliable predictors of naturalistic pyramidal-neuron voltage traces

Wulfram Gerstner, Laurent Badel, Carl Petersen, Sandrine Lefort, Romain Brette

Neuronal response properties are typically probed by intracellular measurements of current-voltage (I-V) relationships during application of current or voltage steps. Here we demonstrate the measurement of a novel I-V curve measured while the neuron exhibi ...

Spike-triggered averages for passive and resonant neurons receiving filtered excitatory and inhibitory synaptic drive

Wulfram Gerstner, Laurent Badel

A path-integral approach is developed for the analysis of spike-triggered-average quantities in neurons with voltage-gated subthreshold currents. Using a linearization procedure to reduce the models to the generalized integrate-and-fire form, analytical ex ...

Quantitative single-neuron modeling: competition 2008

Wulfram Gerstner, Laurent Badel, Thomas Berger, Richard Naud

How well are single-cell properties reproduced by the present-day neuronal models? Recently, several labs have approached this question by assessing the quality of the models with respect to spike timing prediction or characteristic features of the voltage ...

Dependence of the spike-triggered average voltage on membrane response properties

Wulfram Gerstner, Laurent Badel

The spike-triggered average voltage (STV) is an experimentally measurable quantity that is determined by both the membrane response properties and the statistics of the synaptic drive. Here, the form of the STV is modelled for neurons with three distinct t ...
