Abstract. We describe four recent additions to NEURON's suite of graphical tools that make it easier for users to create and manage models: an enhancement to the Channel Builder that facilitates the specification and efficient simulation of stochastic channel models; an enhancement to the Cell Builder that enables the convenient specification of spatially non-uniform properties in anatomically complex cells; the Model Viewer, which presents a browsable and quickly understood summary of the properties of models of individual cells and networks; and the Import3D tool, which simplifies conversion of detailed morphometric data into computational models of neurons
