a model of the dentate gyrus (dg), ca3 and ca1 microcircuits is presented that uses biophysical representations of the major cell types including granule cells, ca3 and ca1 pyramidal cells (pcs) and six types of interneurons: basket cells (bcs), axo-axonic cells (aacs), bistratified cells (bscs), oriens lacunosum-moleculare cells (olms), mossy cells (mcs) and hilar perforant path associated cells (hc). |

prior studies suggest that, during the acquisition of information from the environment, the dentate gyrus (dg) and ca3 subfields rapidly differentiate competing contextual representations, whereas ca1, situated downstream from ca3/dg, is believed to process input from both ca3 and neocortical areas via the temporoammonic pathway. |
