Résumém de l'exposé de Loïs Naudin Modélisation des trois types de neurones non-spikings chez Caenorhabditis elegans The nematode Caenorhabditis elegans (C. elegans) is a well-known model organism in neuroscience due to its relative simplicity of its nervous system, consisting of 302 neurons and about 7000 synaptic connections. We propose conductance-based neuron models adapted to the electrophysiological features of three non-spiking neurons (RIM, AIY and AFD) of C. elegans. These features are based on current biological research and a series of in-silico experiments that use differential evolution algorithm to determine models reproducing experimental data with high degree of accuracy while being biologically consistent with state-of-the-art research.
