Have You ever wondered about secrets of the mind? We relate most of the unexplored questions about the human body to the brain.
They are a complex organ that stores information about life, death, consciousness, sleep and a little more.
When You wake up on a nice day, You see the sun rising; You hear birds chirping and maybe even feel the fresh air blowing in the morning and think: yes, I’m happy.
Here, it all means We are conscious. Consciousness is a very complex phenomenon that has occupied the minds of scientists since prehistoric times, but only recently has neuroscience seen it as a real research topic.
The hardest nut to crack in this area has proven to be the process by which the brain creates a subjective experience – it has yet to be explained, researchers have only longed for questions.
Eternal life? This is probably not realistic. However, discoveries in a new field called cryonics could give people a second life.
The Alcor Life Extension Foundation in Arizona, for example, in Crionics centers the bodies of the dead are stored in containers filled with liquid nitrogen.
They cool it to a stagnant -195 C. The cryonics are because a person who has died of a currently incurable disease could be thawed and revived in the future when drugs are found.
One freezer in the Alcor center stores, for example, the remains of baseball legend Ted Williams. Williams, like all other “icicles”, is in the liquid upside down.
This is so that in the event of a leak in the tank, the brain remains immersed in the cold fluid. So far, none of the frozen ones have been refreshed, because the technology hasn’t been invented.
It is not so simple – for example, if thawing did not take place properly at the required temperature, the cells would turn to ice and explode.
The Mystery of Mortality
Eternal life is just a Hollywood movie field. But why does a person grow old? Coming into the world, we are armed with a variety of powerful mechanisms to fight disease and injury.
One would think that they would be enough to escape stiff joints and other injuries. However, as we age, these mechanisms no longer work so well, resulting in reduced resistance to physical injury and stress.
There are many theories about aging, but in principle they are all based on one of two assumptions.
- Aging is linked to human genetics and obviously has some positive effects.
- Aging has no specific purpose, it is only the result of lifelong cell damage.
There are scientists who believe that over time, we will be able to find ways to slow down aging, at least to double the life expectancy.
Heredity Or Upbringing
Scientists, and not just scientists, have long argued about the role of genes and environment has in our way of thinking and personality.
There is no lack of evidence for either party. As we now know how to study genes, they have found it that there are many trait features that we have.
virtually no control over, but there are many areas where our nature and actions are strongly influenced by societal pressure or upbringing.
Why Are We Laughing
Laughter is one of the most enigmatic phenomena associated with human behavior. Scientists have found that laughing activates three regions of the brain.
- The part of thinking needed to understand a joke.
- The part of the movement that moves the muscles needed for laughter.
- The emotional part that creates a feeling of “sadness”.
It’s very clear, but what’s up to it if you still don’t know why one person laughs at silly jokes and another when watching horror movies.
Laughter is a playful reaction to strangeness – situations that do not meet expectations.
Some scholars believe that laughter could also be a way to signal to others that an action is meant to be a joke. Anyway, there is no doubt about it: we feel better when we are laughing.
There are events in a person’s life that are hard to forget. For many, it’s like the first kiss.
But how do these memories remain? Scientists are trying to find out which brain processes create and store memories.
The hippocampus in the gray matter of the brain could be like a memory box.
But there is a peculiarity – memory storage is non critical, so similar regions of the brain are activated by both real and fake memories.
To understand which memories are real, some researchers ask participants to remember the context – if something hasn’t really happened, it’s much harder.
Understanding human mind is not that easy. The hypothalamus has a suprachiasmatic nucleus or biological clock that programs the body to a 24-hour rhythm.
The most noticeable effect is the sleep and wake cycle, but the biological clock also affects –
Scientists have found that light intensity can cause shifts in the hormone’s regulation melatonin.
There has been a recent debate about whether melatonin supplements can help prevent fatigue after long flights when the body needs to get used to changing time zones.
In about 80% of cases, people who have had a limb amputated experience the heat, itching, pressure, or pain that appears to come from a lost part of the body.
Pain in amputated limbs is called “phantom pain.” Patients suffer as much pain as if the amputation had not taken place.
One explanation is that nerves form new connections with the spine at the incision and continue to signal the brain.
The second possibility is that we program our body so that the brain always feels that it is healthy, the brain thinks body always has all the body parts.
This is done by fruit flies. This is what tigers do. And people like it so much that it is never enough.
No, that’s not what you think. It’s about sleep – so important that we spend more than a quarter of our lives on it. This is another mystery of the mind.
And so enigmatic that we still don’t know why we have to sleep. One thing is clear: sleep is extremely important for mammalian survival.
Prolonged insomnia causes mood swings, hallucinations, and in extreme cases can lead to death.
There are two phases of sleep: the REM (Rapid Eye Movement) phase, when the cerebellum is very active, and the NREM, when the brain has very low metabolic activity.
Some scientists believe that NREM sleep is the right to rest and saves energy because it is like the hibernation of animals.
REM sleep may help organize memories. However, these beliefs have not been proven, and the dreams we see in the REM sleep phase do not always coincide with memories.
