Motivational processes and fuzzy logic of the brain part 1: experiment (the ability to feel rests on the fact of mortality)

Many theories relate to the brain as a complex network of neurons, which are approximated as simple elements that make summation of excitations and generate output reaction in accordance with simple activation functions. Such an idealization, however, is far from the properties of a real neuron. In the first part of this paper we present a comprehensive review of the literature and results of the original experiments which supply trustworthy evidence that a real neuron makes a prediction of consequences of input signals and generates an output signal in conformity with this prediction. Based on the experimental data we point out that the phenomenon of motivation appears already on the neuronal level as the phenomenon of avoidance of neuron damage. We argue also that avoidance of injury and aspiration to live is one of the main parts of physiological regulation of the neuron learning and the motivational processes.
