Abstract
The hippocampus is responsible for the formation of episodic memory. Recently, it was observed that atrophy of the hippocampus can lead to Alzheimer's disease. Thus, it would be important to investigate the mechanism of the formation of episodic memory in terms of the neural network model of the hippocampus. In the present study, we investigated a coding scheme of spatio-temporal inputs to CA 1 of the hippocampus. We found that Cantor sets produced in the space of membrane potentials of CA 1 neurons represent input time series in a hierarchical way. A similar behavior has been observed in experiments with rat hippocampal slices.
