Some neurons ignite only when conscious perception occurs.

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".


Our conscious perception of information results from a large wave of neuronal activity in the cortex extending beyond the ignition range.

The information consciousness at this time will eventually lead to a state like the WEB, where many brain regions are closely intertwined. And then there is a global ignition.

Approximately 300 milliseconds after the occurrence of the stimulus, information is transmitted to the brain region. This frontal lobe in a bottom-up manner during the period during which the conscious state is maintained.

On the other hand, the frontal lobe is top-down and makes large-scale launches over large areas of the brain.

The result is a web of brains that works in tandem with areas in sync with each other.

And it shows the following signs of consciousness.

Activation dispersed in the frontal and parietal lobe regions

P3 wave

Gamma band amplification

Large-scale synchronization between remote areas

How does the brain distinguish the code of pure consciousness from the unconscious this time? Raise it to consciousness? I want to elucidate the mechanism.

As we walk down the corridor, changing images enter the retina from the wall, but we are unaware of such visual movements and perceive a room without movement.

The eyeball moves quickly three to four times a second. As a result. The entire image of the outside world sways, both on the retina and in the visual cortex.

We are unaware of this movement, and our perception is constant.

I don't see the background skidding in the opposite direction, even when looking at a moving object.

Given this, the code of consciousness should be equally stable within the cortex.

Thanks to the motion sensors in the inner ear and predictions based on motion commands, our brain somehow subtracts our motion and perceives the outside world as an immutable entity.

For example, television images blink 50 to 60 times per second, but in EEG recordings, the rhythm is captured in the primary visual cortex, where neurons blink at the same frequency.

But we are unaware of this blink. The details that come into the visual cortex are filtered before reaching consciousness.

Consciousness can dramatically enhance or transform the input image, but we do not see the outside world as if we were looking through a magnifying glass but focused on faces and letters. It doesn't suddenly magnify.

In this way, consciousness constantly stabilizes perception.

The initial visual response does not include the code of consciousness.

Much processing is required for the brain to solve perceptual puzzles and form a stable image of the outside world.

Neuroscientists Rodrigo Kian-Quiroga, Itzak Fried, Rafi Marak,

Reacts only to specific pictures, places or people,

He discovered a neuron that ignites only when conscious perception occurs.

During the global ignition, the midbrain is not in a state of global excitement. Still, the subjective content of consciousness is accentuated by the activation of only a limited group of neurons.

Like most animals, cortical neurons in the human brain exchange discontinuous electrical signals called "spikes." Excited neurons usually emit a few spikes per second.

Each spike travels along the axon to reach the target quickly.

Fried's experiments also allow awakened patients to record all the spikes emitted by a particular neuron for hours, or even days, during their daily lives.
