Kurzfassung englisch:
Individual neurons in the nervous systems exploit various dynamics. To capture
these dynamics for single neurons, we tune the parameters of an electrophysiologi-
cal model of nerve cells, to fit experimental data obtained by calcium imaging. A
search for the biophysical parameters of this model is performed by means of a
genetic algorithm, where the model neuron is exposed to a predefined input current
representing overall inputs from other parts of the nervous system. The algorithm
is then constrained for keeping the ion-channel currents within reasonable ranges,
while producing the best fit to a calcium imaging time series of the AVA interneu-
ron, from the brain of the soil-worm, C. elegans . Our settings enable us to project
a set of biophysical parameters to the the neuron kinetics observed in neuronal
imaging.
