Recently, the hippocampal-dependent declarative memory was reported in humans. It indicated that the non-spatial information, smell, influenced on the processing of the spatial information, place. While, rat hippocampal granule cells have inputs to the Lateral dendrite (LD) though the lateral perforant path (LPP) with non-spatial information, smell etc., and inputs to the Medial dendrite (MD) though the medial perforant path (MPP) with spatial information, place. Both of them are originated from layer II in the entorhinal cortex (EC). Therefore, comparing with the report in human, there is a possibility that the processing of spatial information is influenced by non-specific information in dentate granule. In this study, to clarify how spatial information and non-spatial information are integrated, electrophysiological experiments and additional simulations experiments were preformed. As the result, the pattern discrimination of spatial information was enhanced by non-spatial inputs. |
