Abstract
We have found that single neuronal activities in various brain regions commonly exhibit the dynamics transition from the white to the 1/f spectral profiles during sleep cycle in cats. Simulations using the neural network model showed that the global inhibitory input could induce that transition. Especially, under the weak inhibition (the physiological situation of dream sleep), the metastability of the network attractor was found to be dominant. In this paper, the metastable behavior of the network is investigated for the symmetry and the asymmetry structures, which can be interpreted by the simple schemes based on the potential energy. The metastability could be a cue to understand the function of dream sleep.
