Animal 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".


It is unthinkable that animals, like us humans, do not have a conscious experience.

The consciousness workspace plays a vital role in facilitating information exchange between different brain regions.

Macaque monkeys have a network of long-distance neural connections that connect the prefrontal cortex with other related cortex.

Even mice have a small prefrontal cortex and cingulate cortex, which have also been activated in retaining visual information.

Therefore, the workspace system may be equipped for all animals belonging to mammals.

I don't think the judgment of an animal's consciousness should be based on the body's anatomy.

Although not linguistic, monkeys can be trained to report what they see by pressing a key on their computer.

There is growing evidence that monkeys have a subjective experience similar to humans.

Train monkeys by pressing one key when they see the light and another when they don't.

The monkey has no language ability, but by pressing a particular key, we can understand that the monkey said, "I think I saw the light" and "I didn't see anything."

It is also possible to teach monkeys to classify perceptual images, such as pressing one key when looking at a face image and another key when looking at a non-face image.

As a result, it was found that monkeys experience the same optical illusion as humans. Furthermore, presenting different images to the monkey's eyes revealed a binocular struggle.

The images are presented differently in both eyes like us humans rise and fall in consciousness.

After flashing the image and displaying a random mask, the macaque monkey reports that the visual cortex had a short-term selective neurons discharge but did not see the hidden image.

In this way, macaque monkeys, like humans, have some form of sub-sense perception and thresholds for image visualization.

When the primary visual cortex is damaged, monkeys also experience blindsight.

However, despite the monkey's damage, it can accurately point to the light source inside the damaged field of view.

However, if you train the monkeys to report the presence or absence of light, you can press the "no light" key to classify the stimuli presented within the impaired visual field.

This fact indicates that, like human blind patients, their perceptual awareness is lost.

Macaque monkeys use the workspace in their brains to look back on the past.

Like humans, it maintains the discharge of neurons in the prefrontal cortex and parietal lobe.

We also know that when macaque monkeys are watching a movie, the prefrontal cortex is more likely to be activated than humans.

Humans seem to be superior in their ability to control distractions.

Also, while watching a movie, the human prefrontal cortex can separate itself from the flow of external information and allow the mind to fly freely.

Macaque monkeys also have a voluntary "default mode" network of activated areas at rest.

These areas are the same areas that are activated when we introspect, remember something, or fly our minds.

What about the topical/global test used to test the residual consciousness recovering from a coma?

We tested whether the monkeys noticed that "Bee Boo Boo" was an exception in the continuous "Bee Boo Boo" sound. As a result, it was found that the monkeys were aware of it.

fMRI images showed that the monkey's prefrontal cortex was activated only in response to global deviant sounds. Like humans, this reaction disappears when monkeys are anaesthetized.

In another experiment, this test also detected a sign of consciousness in mice.

In the future, this test on various species will find evidence of the convergent evolution of some form of consciousness workspace in all mammals and perhaps many species of birds and fish.
