title: Activity in cortical-like neural systems: short-range effects and attention phenomena.
abstract: The kinetic model of cortical-like neural systems is amplified with elements related to a gross lamination in three parts of the basic system. A reduced version of the model, aiming to study only short-range, random aspects of activity propagation, was subjected to an intensive computational experimentation, and the results are briefly presented. The comparison of these results with those of a previous paper, in which aspects related mainly to long-distance effects were described, suggested the possibility of extending the model by considering new features related to phenomena of attention. The results of experimentations with the whole model revealed the possibility of laying the bases for a description of the cognitive activity in a neural frame.
