DETERMINING A DISTRIBUTED CONDUCTANCE PARAMETER FOR A NEURONAL CABLE MODEL DEFINED ON A TREE GRAPH

In this paper we solve the inverse problem of recovering a single spatially distributed conductance parameter in a cable equation model (one-dimensional diffusion) defined on a metric tree graph that represents a dendritic tree of a neuron. Dendrites of nerve cells have membranes with spatially distributed densities of ionic channels and hence non-uniform conductances. We employ the boundary control method that gives a unique reconstruction and an algorithmic approach.
