要 旨 :
The quantum model of brain has been extended to dissipative dynamics in order to solve the problem of memory capacity. This gave rise to an interesting framework to study consciousness related mechanisms. The brain is modeled as an open system interacting with the environment and the information storage is represented through the dynamical generation of collective modes under external stimuli. We find different life-times for modes of different momentum. This suggests interesting features related with memory persistence time. Also stimulated by the increasing interest in quantum features of neural net dynamics, either in connection with information processing in biological systems, or in relation with a computational strategy based on the system quantum evolution (quantum computation), we study the classical limit of the dissipative quantum brain dynamics in order to exhibit a link with neural net dynamics.
