The unconscious has several alternatives images, but only one is raised to consciousness.

Updated: May 29, 2022

By studying "Study of Consciousness", I would like to think about coaching theory, such as rewriting my unconsciousness.

This series of blog posts are my study notes.


I wrote in my last blog that many neurons collaborate in statistical processing to create a single video image.

Looking at the movement of a figure that is a little more complicated than a circle. Such as a rectangle. If you are looking at the local area, ambiguous parts do not connect to the rectangle.

However, each side of the rectangle has hinted about movements associated with the perceptual image, and the unconscious uses it to recognize it as a rectangle.

The direction of movement between each side of the rectangle is the same.

The unconscious infers it and shows only the movements that meet the conditions of the consciousness.

Looking at the activity record of the neurons, the neurons in the MT area "keep looking at only local movements for 100 ms and code the direction of global movements in 120-140 ms. But consciousness. Is unaware of this complex underwater operation.

Our consciousness (subjectivity) sees only the final result without recognizing that the neural circuit works at full power to transform the initially ambiguous sensory input into an understandable perceptual image. It is.

The underwater process of concentrating neurons in one interpretation is ineffective under anaesthesia.

It takes the consciousness work for neurons to agree with each other through the transmission of both bottom-up and top-down signals.

Without consciousness, the perceptual reasoning process becomes incomprehensible to the outside world.

Experimentally, it is clear that consciousness eliminates perceptual ambiguity by deliberately creating ambiguous visual stimuli.

Show the subject moving the two stacked discs of plaid in different directions.

The brain has no way of determining which plaid is in front.

The two overlapping plaid patterns are ambiguous, and both can be perceived as being in front.

But in reality, we are looking at one of two possibilities.

Consciousness recognizes one of the two plaid patterns as being in the foreground.

The two interpretations alternate, with perceptions changing every few seconds, and the plaids that were previously visible on the back pop out to the front.

We always tend to recognize what we think is most likely.

From time to time, another interpretation emerges, and the image remains in a conscious view while it is considered valid.

We are always ready to adopt alternatives, considering all other interpretations of the unconscious, even if we consciously make only one interpretation of the vague sights of the outside world.

Since only one image is captured in our consciousness, we are unaware that our vision is performing complex operations.

When you open your eyes, your brain shows us a scene of the outside world.
