This is extended to the meaning construction in social interactions. A bidirectional model is proposed using script paradigm in which to each participant is attributed complementary generative functions and transformation operators of action/reaction. The interaction has a trajectory that unfolds in time of successive stages in which the criteria depend not only on the present conditions but also from future anticipated states which adds temporal and intentional dimensions to the model. The distance within this space of qualities determines the intensity and valence of emotions.

In CNS, messages are simultaneously expressed in a linguistic form, in commands or behaviours, and in neurophysiologic processes and decisions. The meaning and intention of states expressed in a linguistic form engage anticipatory and consummatory references, intentional declarative processes and neurophysiologic decisions. From a systemic viewpoint, the meaning and intention of a concept can be formulated taking into account respectively state transition matrices which, given a certain state and an input specify respectively the next state of a system and its output. The meaning and intention of a concept are specified by a set of decision rules which allow its inclusion in the class of equivalence that specifies the concept in extension.

At present, a new type of process for signalling between cells seems to be emerging, the Volume Transmission (VT). Its underlying mechanism is the diffusion of neuroactive substances and diffusible signals, like nitric oxide (NO), in the extracellular space (ECS), extra-synaptic gap which affect the brain activity in a global way. This paper is dedicated to the Theoretical Framework of the global study framework of NO diffusion (GSFNO). We present a new model of NO diffusion based in compartmental sytems and transport phenomena, which allows to understand how NO functions as a neural signalling molecule. We model the dynamic of NO diffusion from a molecular level where the spatial dimension is discrete. This model is highly powerful for studying and determining the dynamic of NO production and diffusion, both in brain and artificial neural systems, showing the capabilities of NO in cellular signalling and learning and its influence in the anticipatory behaviour. It has category of general formal tool with biological plausibility. We present a short analysis of the model in a three-dimensional environment for properties such as the dynamic of NO release, the self-regulation effect, the diffuse neighbourhoods (DNB), among others.
