(A) A 2-D rendering of the biologically realistic NEURON model of a rodent dentate gyrus with demarcation of recording and stimulating devices. (B) The slice model is populated with 10 k entorhinal cortical axons which synapse with 50 k granule cells. The entire model comprises ≈12.25 million synapses and ≈15 million neuronal compartments. (C) The NEURON model was imbedded in a meshed volume with bipolar stimulating electrodes targeting the perforant pathway. (D) Analytical estimates of LFPs corresponded well with in vitro MEA recordings in temporal dynamics and waveform. Model validation was performed for stimulation at the crest perforant path and recordings from the suprapyramidal cell body layer. Details regarding the construction and application of this model are described at length in Bingham et al. (2018a).
