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.
