Abstract :
We review phenomenology of the dynamics-transition of single neuronal activities during sleep and summarize results of simulation. We study the generation mechanism underlying the dynamics-transition, based on the structural analysis of network attractors under various conditions. From these studies, we discuss what is happening in actual neural networks, with possible contribution to brain function.
