This model was implemented by Rob Morgan in the Soltesz lab at UC Irvine. It is a scaleable model of the rat dentate gyrus including four cell types. This model runs in serial (on a single processor) and has been published at the size of 50,000 granule cells (with proportional numbers of the other cells).
Model Type: Realistic Network
Region(s) or Organism(s): Dentate gyrus
Model Concept(s): Epilepsy
Simulation Environment: NEURON
