The dissipative quantum model of brain: how do memory localize in correlated neuronal domains

Eleonora Alfinito, Giuseppe Vitiello

Published Jun 14, 2000• 0 citations
arXivHTMLPDF

Abstract

The mechanism of memory localization in extended domains is described in the framework of the parametric dissipative quantum model of brain. The size of the domains and the capability in memorizing depend on the number of links the system is able to establish with the external world.

Dissipation and memory capacity in the quantum brain model

Vitiello, G

The quantum model of the brain proposed by Ricciardi and Umezawa is extended to dissipative dynamics in order to study the problem of memory capacity. It is shown that infinitely many vacua are accessible to memory printing in a way that in sequential information recording the storage of a new information does not destroy the previously stored ones, thus allowing a huge memory capacity. The mechanism of information printing is shown to induce breakdown of time-reversal symmetry. Thermal properties of the memory states as well as their relation with squeezed coherent states are finally discussed.

Entanglement and Phase-Mediated Correlations in Quantum Field Theory. Application to Brain-Mind States

Shantena Augusto Sabbadini, Giuseppe Vitiello

The entanglement phenomenon plays a central role in quantum optics and in basic aspects of quantum mechanics and quantum field theory. We review the dissipative quantum model of brain and the role of the entanglement in the brain-mind activity correlation and in the formation of assemblies of coherently-oscillating neurons, which are observed to appear in different regions of the cortex by use of EEG, ECoG, fNMR, and other observational methods in neuroscience.
