Feasible neuron and synaptic network simulation

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".


I have seen in previous blogs that information in the unconscious stage can be classified into five categories.

Five forms of unconscious information

Three unconscious categories: "Unconscious", "Preconscious", "Separated pattern"

Five forms of unconscious information

A vast amount of knowledge is accumulated in the brain. But we can only notice a small part of that knowledge.

We have accumulated in the brain to conscious access for target the knowledge. Information needs to be encoded in organized cortical areas where the activity of neurons is connected.

This pattern must ignite a neural circuit that is tightly coupled to each other, called the global workspace.

This phenomenon of long-distance tissue ignition can be explained as a "sign of consciousness" in experiments using brain imaging.

Computer simulation can reproduce some of the characteristics of conscious access.

This simulation has not yet reached the point of imitating the actual brain. But in principle, it is possible to simulate the state of consciousness in detail by computer programs.

As computer simulation evolves, it will be possible to maintain the billions of "signs of consciousness" that neurons are doing in computers.

In addition, valuable statistics such as detecting a specific face based on the input information and calculating whether or not the target can be reached, rather than simply propagating the activity in the brain through the nervous system tract. Finally, you will be able to perform inference.

The study of how to wire a network of neurons to enable such statistical calculations has just begun.

Accumulating the noisy evidence provided by neurons results in rudimentary perceptual decisions.

When the ignition of consciousness occurs, some of those neurons reach a unified interpretation and decide what to do next.

These brain regions are constantly trying to find a consistent interpretation based on the mixed messages.

Then, through long-distance neural connections, we will collate disparate information at a global level and accumulate evidence until we have a consistent answer that meets our immediate goals.

The brain is only affected by an external input to a certain extent.

The autonomy of the brain is essential. The autonomously active brain sets its own goals, and the other brain activities are formed from the higher dimensional areas to the top-down accordingly.

In this way, the brain draws long-term memory, forms mental images, and guides other areas to transform them according to logical and linguistic rules.

The activity of neurons circulates in the workspace in the brain. And every time we get some consistent results, we take a new step in the flow of conscious thinking.

In Europe, researchers are gathering at the Human Brain Project to undertake groundbreaking attempts to understand and simulate the human cortical network.

It is already feasible to simulate a network consisting of millions of neurons and billions of synapses by using a "neuromorphic microchip" (a microchip that imitates the brain) as a base.

Overview at the beginning of the Human Brain Project (HBP) HP

"The Human Brain Project (HBP) is one of three FET (Future and Emerging Technology) flagship projects. It started in 2013 and is one of the most significant research projects in the world. More than 140 universities and education across Europe. More than 500 scientists and engineers from hospitals and research centres have come together to work on one of the most challenging research goals, the human brain. "
