| Outline of Final Research Achievements |
In hippocampal CA1, low-frequency gamma oscillations reflect context inputs, while high-frequency gamma oscillations reflect sensory inputs. We investigated the interaction between these inputs in learning and memory by using computational model and physiological methods. In physiological study, by using slice preparation, we applied spatiotemporal information, which mimics context and sensory information, and analyzed the accuracy of cantor coding. In theoretical study, we constructed a CA1 network model, which integrates context and sensory inputs.
