  In this paper we present a new neurobiologically-inspired affective cognitive
architecture: NEUCOGAR (NEUromodulating COGnitive ARchitecture). The objective
of NEUCOGAR is the identification of a mapping from the influence of serotonin,
dopamine and noradrenaline to the computing processes based on Von Neuman's
architecture, in order to implement affective phenomena which can operate on
the Turing's machine model. As basis of the modeling we use and extend the
L\"ovheim Cube of Emotion with parameters of the Von Neumann architecture.
Validation is conducted via simulation on a computing system of dopamine
neuromodulation and its effects on the Cortex. In the experimental phase of the
project, the increase of computing power and storage redistribution due to
emotion stimulus modulated by the dopamine system, confirmed the soundness of
the model.
