| Research Abstract |
Animals have an excellent ability to perceive various odors robustly, even when the environment is dynamically and unpredictably changing. Here, we proposed a computational model in which the concentration-invariant odor information is represented by the spatiotemporal activity of network. The represented odor information is easily evaluated and stored by another network model for the higher olfactory center. In our model, transforming the input spatial pattern inlo the invariant spatiotemporal order is essential for representing the odor information and output patterns of the Proposed networks are consistent with those of the biological ones.
