A brain is a place of competition for potential information.

(Cognitive science) In coaching, rewriting the unconscious is a powerful means of achieving the goal.

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


This series of blog posts is my study note.


 

Nicos Rogosetis and David Leopold trained monkeys to use levers to report what they saw.

As a result of this experiment, it was found that monkeys also experience this illusion. Therefore, they also experimented with recording the activity of neurons in the brain.



As a result, no optical illusion was observed in the visual processing at the initial stage (V1 and V2 regions).

Most neurons coded both images equally.




But at higher levels of the cortex (IT: inferior temporal cortex) and STS:

superior temporal sulcus)

Most cells correlated with subjective awareness.


The discharge rate of these cells indicates which image is being viewed subjectively.

The figures show the rate of cell firing in different brain regions.


In this experiment, we recognized conscious perception in the higher associative cortex.


Over time, the same image changes and becomes fully visible or completely disappears from the range of conscious perception.


I confirmed that monkeys, like humans, randomly alternate between the two images.


And finally, the neurons that react as the monkey's favourite image goes in and out of consciousness.

I also succeeded in finding out.


Many cells responded equally in the primary visual cortex, which is the gateway to the cortex of visual information.


However, as we advanced to the higher visual cortex, we confirmed that the neuronal response gradually increased to monkey consciousness.


When the monkey saw his favourite image, he pulled the lever firmly and responded, and when he suppressed, he responded only slightly.


In addition to this, various experimental methods are being considered.


For example, in a method called "continuous flash suppression", if you continuously flash a rectangle with a bright colour to one eye, only that image will be visible.


This way, you can remove one of the two images from your field of view.


Even if the eyes show a visual image for a long time and that information is transmitted to the brain area that controls the visual process, it can be excluded entirely from the conscious experience.


Since consciousness cannot capture two objects located in the same place simultaneously, the brain becomes a place of fierce competition, and innumerable potential perceptual information constantly competes in the brain for awareness by consciousness. There is.
