Introduction: This article discusses the brain hierarchical organization/evolution as a consequence of the information-induced brain
development, from the perspective of the Informational Model of Consciousness.
Analysis: In the frame of the Informational Model of Consciousness, a detailed info-neural analysis ispresented, concerning the specific
properties/functions of the informational system of the human body composed by the Center of Acquisition and Storing of Information, Center of
Decision and Command, Info-Emotional Center, Maintenance Informational System, Genetic Transmission System, Info Genetic Generator and Info-
Connection center, in relation with the neuro-connected brain areas, with a special attention to the Info-Connection and its specific properties.
Besides a meticulous analysis of the info-connections/neuro-functions of these centers, a special attention was paid to limbic/cingulate cortex
activities. Defined as a trust/confidence center, additional features are highlighted in correlation with the activity of the anterior cingulate cortex,
consisting in the intervention/moderation of amygdala emotional signals, conflicting opposite YES/NO data and error elimination in the favor of the
organism adaptation/survival, the intervention in the certainty/uncertainty balance to select a suitable pro-life information (antientropic effect), in
moderation of pain and in the stimulation of the empathic inter-human relations/communication. Representing the correspondence between the
informational subsystems and the brain area map, itis shown that the up/down integration of information by epigenetic mechanisms and the down/
up evolution are correlated.
Results: The analysis of the functions of the anterior cingulate opens new gates of investigations concerning the involved intimate mechanisms
at the level of cell microstructure, specifically on the compatibility with quantum assisted processes admitted by the Informational Model of
Consciousness and the quantum-based models The discussion on the information integration/codification by epigenetic mechanisms shows that
this process starts from the superior levels of brain conscious info-processing areas and progressively advances to the automatic/autonomic inferior
levels ofthe informational system, under insistent/repetitive cues/stress conditions, pointing out an hierarchical functional/anatomical structure of
the brain organization. Additional arguments are discussed, indicating thatthe down/up progressive scale representation is a suggestive illustration
of the brain evolution, induced/assisted/determined by information, accelerated at humans by the antientropic functions of the Info-Connection
Conclusions: The hierarchical organization of the brain is a consequence of the integration process of information, defining its development
accordingly to the adaptation requirements for survival during successive evolution stages of the organism, information playing a determinant/key
