Neural cortex dichotomy and human consciousness

by Felix Brehar

The underling mechanisms of processing the information by human cortex remain an unsolved problem and a major challenge for neuroscience researcher. To imagine cortical activity like a powerful computer is an easier way to solve the problem but also could be a huge mistake.

In this short paper we try to find a model of neuronal architecture substrate for an unexplained specific human state: consciousness. This is what it makes us different for other primate.

To obtain the state of awake a constant activity of ascendant activating systems and of certain thalamic neurons networks are required. The neuronal architecture of the cortex can be alike with a complex three-dimensional mirror of the external space and of the body. The three-dimensional architecture of neuronal networks is probably the key of way of coding and decoding of information at the cortical level.

In human cortex is seems to be very important the capacity of neuronal populations to split up (schism). So we have a primary area, which processes first the information, and these will transmit to the second area that is able to connect to the other areas which processing different kind of information. Thus associations between different encoded information could be made. The neurons connect each other by the rules of mathematic models of neuronal networks. Because of high capacity of splitting of populations neurons and of connection between these, language is so develop and complex in humans.

But in human brain is happen something special and is referred to phenomena occurs probably in dominant angular cortex: areas 39, 40, in language areas (Broca and Wernicke's areas) and at the level of prefrontal lobes. Humans are not especially because of their capacities of communicate each other, but rather because of their capacity to communicate to themselves. Neuronal networks, which encoding languages and conceptual world are splitting, resulting in two neuronal networks, which modulate each other. The balances between their activities create the state of consciousness. A misbalance of these neuronal networks activity could provoke severe mental illness such schizophrenia.

In fact, this is the model to follow in attempting to create artificial entities, autonomous and capable of developing alone.

This is a general concept. Following this concept we will publish more papers about the models of neural network dichotomy and we will try to discover the elementary laws of cortical information processing.
