A study on A dreamer? We think we are dreaming there !!

So I'm right, right? : Lol: : Lol: : Lol:

What matters is our perception of things?

Then if you believe that psychological time does not exist, remember your philosophy lessons! : Cheesy:

Sorry ? Sorry ?

"The trap of our brain is that it has done so well that today it is digging our grave"



Ah, I got it!

Here is a nice example of an incomprehensible sentence taken out of context (the specialty of some trolls ...)

Hello,

your brain produces between 12 and 25 watts of electricity. This is more than enough to power a low wattage LED bulb.

It might sound surprising to you, but most brain surgeries can be done while the patient is awake, and those without any pain or discomfort. The brain has no pain receptors

it is normal for your mind to wander in the middle of the day. A joint study by Harvard University, Dartmouth College and the University of Aberdeen in Scotland found that parts of the brain that control "task-free thinking" (such as daydreaming) are almost always active when brain is at rest.

It is no coincidence that some countries have chosen to have seven-digit phone numbers. Our working memory, which is a form of very short-term memory that stores ideas just long enough for us to understand them, can hold, on average, a maximum of seven digits. This allows you to search for a phone number and remember it just long enough to dial it.

Most scientists claim that there is no evidence to date that playing classical music in babies increases their intellectual capacity. However, it is recognized that children who learn to play a musical instrument may develop their mental capacities in more advanced ways than other children.

. There are 2,5 million gigabytes of storage space in your brain. For your information a top-of-the-range model of the latest generation of iPhone is "only" equipped with 1024 gigabytes.

The brain of an adult human weighs around 1,5 kg and although it is only 2% of the body's weight, it uses around 20% of its energy.

If all the blood vessels in your brain were placed end to end, it would be half the distance between the earth and the moon (approximately 190,000 kilometers)

Reading aloud promotes brain development. This is indeed one of the weird facts about the brain because we usually teach our children to read silently. But to help your child's brain develop, you should have them read aloud.

. The human brain's ability to concentrate has been declining for several years. We have lost almost four seconds of our attention span over the past 15 years. This means that we cannot focus on one thing for more than eight seconds on average.

A study of New York college students found that those who ate meals that did not include artificial flavors, preservatives, and colors scored 14% better on IQ tests than college students. who ate meals with these additives.

Unsurprisingly, our brains prefer images to text. Study participants remember only about 10% of the information presented orally when tested 72 hours after teaching. However, this number increases by around 65% when an image is added to the learning process.

There are about 100 billion neurons in a human brain, the same number of stars as in the Milky Way.

Are you feeling tired? Go ahead, yawn. Yawning cools the brain, research shows. Lack of sleep increases the temperature of the brain.

our brains weigh half as much as our skin does? The next time someone calls you chubby, take it as a compliment because that means you have a bigger brain too. The human brain is considered to be the most fatty organ in the human body. A normal human brain weighs 3lbs, of which 60% is nothing but fat.

Yes it is good for your brain to forget things because when you forget something it means your brain is deleting some unnecessary information. This is good for your nervous system because it helps keep its plasticity. The next time you forget something, remember that it is not your fault that your brain thought that was some unnecessary information.

The human brain uses 20% of the total oxygen and blood in our body. Our brain can normally survive for up to 4-6 minutes without oxygen, after which it slowly begins to die. Lack of oxygen supply to the brain for more than 10 minutes - due to suffocation, carbon monoxide poisoning, heart failure, birth injuries, or drowning, etc. - can cause permanent brain damage.

Sounds surprising, right? The human brain also tastes of receptors. We know taste buds in the tongue are responsible for the kind of taste, but we get these sensors present in our mouths are just the initials. The most important part of the taste journey is how the brain interprets it. Yes, the brain is responsible for translating what kind of taste we have experienced. There are parts of our brain that are dedicated to different tastes.

The structure of the human brain begins to change from the moment of birth and it continues to do so throughout life. There is a change every time we learn something new. Our brain structure also changes without the use of drugs or life changing situations.

There is a change in the structure of the brain when depression occurs. Many parts of the brain slow down and some parts become overactive. This explains why depressed people feel lethargic and exhausted. The balance of the brain is disturbed. It is mainly due to biological factors, rejection and failure. A recent study shows that violent and rough child rearing can have the same effect on a child's mental state as a soldier's mental condition.

The brain is made up of 3/4 water. Even when only 2% dehydrated, this is enough to cause negative effects on short-term memory and concentration. This is the reason why it is important to drink between 1 liter and 1,5 liters of water per day.

Physical activity is good for your health and is still the best way to stay in shape. But it should not be taken to the extreme: scientists have discovered that after an hour and a half of intense effort and sweating, the brain begins to shrink. During 1 minutes of physical activity, he shrinks as much as he normally would in a year. Not surprisingly when you consider that it is made up of 30% water. It is therefore advisable to drink a lot, especially during physical activity, and to do small sessions rather than long.

You almost feel insulted, but it's scientifically proven: attention spans are 8 seconds in humans and 9 seconds in goldfish. This is the reason why we can do several things at the same time!

the human brain has shrunk since prehistoric times

93% of your body mass is actually stardust. The majority of the elements that make up your body (your bones, organs, muscles… are made of various atoms and molecules) were created by the stars.

an average adult is composed of 7 quadrillons of atoms, i.e. 7,000,000,000,000,000,000,000,000,000

Wait there are you saying that we are all lights there?

Don't you want to ask the government to relight theirs? : Lol: : Lol: : Lol: : Lol:

I just gave the facts indeed ... The brain is the control of our body. It interferes with our environment and it is an interpreter so it listens then it transmits and it follows that the brain transmits information to the mouth The brain is the organ that works the most consumes the most yet it is not that big.

The dream manages to make you believe that you spent weeks there through ellipses and false memories.
The inception thing is bogus.


Studies of this kind should be taken with a grain of salt because it is not really possible to say that all the phases of dreams have been exploited during the experience, especially with regard to the multiple levels of the activity. cerebral.

There are different levels of mastery in the art of "lucidology" (the practice of lucid dreaming).
Overall, the studies on subjective temporality seem to confirm the theses of the film Inception.
Child psychiatrists, for example, insist on the fact that children do not have the same intensity of perception of time as adults.
Studies show (they are confirmed by those carried out in the animal kingdom) that it is the capacity of information processing of the cognitive system which will determine "the impression of the passage of time"*.
The greater the capacity for processing information, the more time appears to the consciousness as being slowed down, and vice versa.

According to Professor Adrian Bejan, it is in this difference that lies the explanation of the enigma. Teaching mechanical engineering at Duke University, he explains that the time we perceive depends on observed changes, for example via visual images. “The human mind perceives reality (nature, physical) through images appearing as visual inputs reach the cortex,” he explains, thus “the mind feels the 'change of weather' when the perceived image changes ".

But there : a young brain receives more images and at a higher frequency for a day than the same older brain. "People are often amazed at how much they remember days that seemed to last forever in their youth," Prof. Bejan said in a statement. "It's not that their experiences were much deeper or more meaningful, it's just that they were treated in a burst ". Because according to him, this apparent time gap can be attributed to the ever slower speed at which images are obtained and processed by the human brain as the body ages.
Aging neural networks

For Prof. Bejan, the size and complexity of neural networks grow over time, forcing signals to travel longer distances. In addition, these networks also age and degrade, giving increased resistance to the flow of electrical signals. As a result of these phenomena, the rate of acquisition and processing of new mental images decreases with age. As a result, since older people post fewer new images in the same amount of time, it seems to them that time flies faster.

According to Christian Yates, mathematician at the University of Bath (England), in The Conversation, other explanations could explain this acceleration of perceived time. His theories come close to Adrian Bejan's explanation: an overall slowing down of our metabolism, joining slower breathing and heart rate, resulting in an accelerated perception of time. Another theory is that our perception of time lengthens as the environment becomes familiar to us. Thus, a child for whom everything is subject to astonishment will register more information over the same period of time as adults, slowing his perception of time.
The time perceived between our 5 and 10 years would be the same as between our 40 and our 80 years!

Christian Yates, however, considers these theories insufficient to explain these differences in perception, especially in view of the magnitude of the perceived acceleration, corresponding to a logarithmic scale. This scale provides for a multiplication by 10 between each unit. It would make it possible to visualize the perceived continuous acceleration of time as a function of age. Indeed, the time already lived would be a good indicator of this perception. For example, a year for a 2-year-old is half her life, but only 10% that of a 10-year-old, and 5% of a 20-year-old. So according to this scale, the perceived duration is exactly the same between 5 and 10 years as between 10 and 20 years, 20 and 40 years and 40 and 80 years ...

"I don't want to end on a depressing note, but the five-year period that you lived between five and ten years may seem as long as that between 40 and 80 years", concludes Christian Yates with humor. "So keep busy. Time flies whether you're having fun or not. And it's going faster and faster every day."

During a lucid dream there are phases where reality is increased, that is to say that the dream world appears more real than the real world itself due to an increase in brain activity.
In fact, in normal times our brain works according to an optimization logic. In order to keep up with the 16 hours of average wakefulness, it runs at half speed. During a period of intense stress (accident, aggression or certain dream phases) are activity is accelerated. It is a kind of sprint where the information processing increases considerably.


* Time does not exist as such, it is a term to designate the increase in entropy, i.e. the measure of the transformation of the real under the action of the second principle of thermodynamics.

You have to listen to Sebastien Bohler.
Like Janco he says that our brains have allowed fantastic technical advances and now faced with the limits of the planet, everything has to be reconsidered.

I think that by focusing as much as possible on efficiency, renewable energies, without neglecting nuclear power to ensure the energy transition, we should be able to survive the dark period of excess CO2 which will poison us for a long time. time... https://www.usinenouvelle.com/editorial ... d.N1164087
