Activated and inhibitory neurons encode consciousness.

Updated: May 29, 2022

Studying the "Study of Consciousness" (Stanislas Duanne) can further deepen your understanding of coaching theory.

I am studying to add a unique flavour to "unconscious rewriting".


This series of blog posts are my study notes. This time, the theme that follows the unconscious and conscious

I will write a "sign of consciousness".


 

We become conscious. Some of the neurons in the workspace are coded by sound activation for hundreds of milliseconds. (Global Neuronal Workspace Theory)


We take one image of the Mona Lisa as sensory information such as "hands separated from the body", "smile", "eyes floating in space", and various other information (name, meaning, da Vinci). I understand the whole image of the Mona Lisa by integrating (such as knowledge about the genius of).


These neurons, dispersed in many brain regions, encode and hold different aspects of one integrated image.


During continued conscious access, neurons in the workspace use their long axons to exchange information and perform large-scale concurrencies in synchronisation.

And when they converge into one, conscious perception is complete.


At that time, the cell aggregate that encodes the content of consciousness spreads throughout the brain,

The pieces of information held by individual brain regions are consistent.

Consistency is maintained because a top-down synchronised image is maintained across all related neurons via axons.


Neuron synchronisation is key to this mechanism.

Neurons far apart from each other synchronise their spikes with the electrical vibrations that continue in the background.

The phenomenon of forming a vast set is captured.


The brain, which encodes our thoughts, harmonises light blinking according to the patterns exhibited by a population of neurons.


For example, inside the language network of the left temporal lobe, the meaning of a word may be unknowingly coded, which may be unconscious but synchronised between limited areas.

However, that information is not widely shared because it is not accessed by the prefrontal cortex and remains unconscious and unconscious.


There are 16 billion neurons in the cortex, each specialising in a minimal range of stimuli.

Even if we focus only on the visual cortex, various neurons correspond to faces, hands, objects, perspectives, shapes, straight lines, curves, colours, depths, and so on.


Each cell conveys only a small amount of information related to the visual scene.

From this little information, one object of thought is selected as the focus of consciousness.


In doing so, all relevant neurons pass through some neurons in the prefrontal cortex.

Activates while partially synchronising.



Non-firing neurons are also involved in the coding of information.

We implicitly tell other neurons that the purpose we are currently conscious of is unrelated to that neuron by silence.

Thus, both activated and silent neurons define the content of consciousness.


During conscious perception, some of the neurons in the workspace are activated. And the rest are suppressed, defining the content of thought at that moment.


Activated neurons broadcast a message throughout the cortex by sending spikes through their long axons.


These signals reach neurons that suppress the generation of action potentials when stimulated.

They then act as silencers and silence the entire group of neurons. "Shut up. You don't need it now." Conscious thinking is thus encoded by a subsection of activated and synchronized neurons and a massive compartment of suppressed and silent cells.


Synaptic currents travel from the surface dendrites to the perikaryon in inactivated cells. Because all of these neurons run in parallel, currents accumulate, and the surface of the head produces slow, harmful brain waves across the region that encodes the conscious stimulus.


However, suppressed neurons dominate the field, and their activity creates positive potentials.

This positive potential eventually forms a large brain wave, as there are far more suppressed neurons than activated neurons.




This phenomenon is the entity of the P3 wave, the second sign of consciousness, which can be easily detected whenever conscious access occurs. Thus, the Global Neuronal Workspace Theory can explain why P3 waves are so robust, inclusive and reproducible.


The focused negative potential defines consciousness, not the diffuse positive potential.
