A purpose of the first part of presented study was to
investigate whether age, education, training, sex and
emotional state influence on process of acceptance of the
decision. This was done by measuring a minimal amount
of information which is required to recognize a visual
image depending on the level of different factors.

Correlation between number of contour fragments needed for recognition
of a visual scene (triangles) and trait anxiety score (circles)
Thus, it was stated that the increasing of level of
anxiety obstructs the recognition of visual signals
and the acceptance of decision. We assume that
emotional factor mainly reveals itself at the step of
integrative analysis of flows of external and internal
information. It is known that qualitative parameters
of integrative processes are controlled by the
nonspecific systems of the brain. So, the reported
difficulty in recognition of visual signals can be
explained by the negative influence of a mechanism
of nonspecific regulation on the integration of
sensory and memorable (bolted in memories)
information under conditions of increasing anxiety.
The absence of understanding of a biological nature of mentality
does not allow to estimate meaning of models of neuronic networks and
their connection with a real brain. For this reason the search of a principle
determining connection of a brain and mentality, is an obligatory first step at
modeling neuronic networks.
Activity of a separate neuron, activity of a brain and the mental
processes have the common organizing factor. The satisfaction of urgent
need is this factor. It is possible to think, that the presence of a common
organizing principle causes integration of neurons in a brain, causes integrity
of a brain and connection of mentality with brain ground. The finding out of
a principle uniting a brain and mentality, is a step to understanding of a
biological nature of mentality and its components (intelligence, memory,
awareness/emotionality).
In a brain there are no structurally allocated blocks of the analysis,
memory and nonspecific regulation. The same structures of a brain
participate in all three functions. This obvious fact specifies on triplet of
processes (1) of the analysis of the information and acceptance of the
decision, (2) record and reading of the information from memory, and also
(3) regulation of awareness and emotional state. The models of neuronic
networks applying for connection with a real brain, should provide triplet of
functions of the analysis, memory and regulation.
The marked above principles allow to address to consideration of a
role of a heredity in formation of mentality and, in particular, of intelligence.
The quality of intelligence is determined by speed and adequacy of the
analysis of the cash information. The analysis is carried out by comparison
to urgent memory for acceptance of the adequate decision. That is, the
quality of intelligence is determined by interaction of analyzing, memorable
and regulatory systems, which features are given genetically.
Thus:
Thus:
1. neuron (it means activity of the integrative neuron in functional unit of a brain
consisting from a inhomogeneous neuronic webs ), brain (it means activity of cotuned
micro- and macrosystems of a brain) and mentality (the intellectual processes of the
analysis of the information and acceptance of the decision, processes of record and reading
of the information from memory, the processes of regulation of awareness and emotional
state) have a common principle of organization (satisfaction of need), this principle
determines their unity;
2. analyzing (analysis of the information and acceptance of the decision),
memorable (record and reading of the information from memory) and nonspecific
regulatory (regulation of awareness and emotions) systems of a brain are structurally
combined - each of brain structures in this or that measure participates in functional triplet;
3. functional features of each system is determined by abilities of neurons to read
out the hereditary information, to reproduce and to duplicate it, forming own memory. In
this memory the results of training during life are fixed. It is supposed, that during
formation of structure of a brain there is a parallel transfer of the hereditary information
about structural architecture and mental architecture.
