摘要

As a first step towards the creation of a cellular model of dentate gyrus (DG) anatomy, we distributed 1,000,000 digitized granule cells (gcs) in 3D in a virtual reality reconstruction of Swanson's brain atlas. DG coronal sections were assembled into 3D surfaces using implicit function generation. The resulting file included hilar, granular, and molecular boundaries. 20,000 replicas of each of 50 reconstructed gcs were added to the model by packing the somata in the appropriate layer and then radially orienting the dendritic tree axes. The model can be used to evaluate stereologic parameters such as dendritic overlap probability, space occupancy, and exposure to incoming fibers.
