Van Pelt and Uylings published several methods of optimizing model parameters to achieve realistic fibre data distributions during neuronal development. Here, the optimization is applied for data obtained by Ger Ramakers.

These are some first results of network generation (with only four neurons) when dendritic growth applies the Samsonovich hypothesis that turns return arbor growth to a somatic normal vector, but axonal growth exhibits turns that are free of such constraints.

A 2002 paper by van Pelt and Uylings describes four different approaches to parameter estimation from data for use with their model of dendritic branching. Specific considerations apply to the choice for one of the methods when simulating network growth according to data by Ger Ramakers.

Preliminary tests with axon growth functions that do not include the dendritic assumptions of turn directions that were based on work by Samsonovich lead to significantly different connection structure in generated networks.
