Modulatory interaction as a support to modeling neural substrates of the decision process

Abstract

There is experimental evidence of neuronal groups projecting widely in the brain which are associated to state functions, like those involved in attention and mood changes. There has been a growing interest in the discussion of the brain functions as being performed by specialized modular systems that can be recombined. It is also suggested the existence of a dichotomy in the neural substrates, which could result or not in the aversion behavior. In the present work, we propose a model that focus on the interaction between modules. This interaction take the form of a modulatory mechanism. In order to explore this model, our tests were conceived with the aim of representing the transposition of an obstacle by a hypothetical organism.
