Mysteries of Human Mind





Sweet Dreams:

If you were to ask 10 individuals what dreams are made of, you’d most likely get 10 various answers. That’s because scientists are still unraveling this mystery. One possibility: Dreaming exercises brain by stimulating the trafficking of synapses between mind cells. Another theory is the fact that people dream about tasks and emotions that they didn’t take care of during the day, and that the process can assist solidify thoughts and memories. In general, experts agree that dreaming happens throughout your deepest sleep, called Rapid Eye Motion (REM).

 

Mysteries of Human Mind

Slumber Sleuth:

Fruit flies do it. Tigers do it. We’re talking about shut-eye, so crucial we invest much more than a quarter of our lives at it. Yet the underlying reasons for rest remain as puzzling like a rambling dream. One thing scientists do know: Rest is essential for survival in mammals. Extended sleeplessness can lead to mood swings, hallucination, and in extreme cases, death. You will find two states of sleep-non-rapid eye movement (NREM), throughout which the brain exhibits low metabolic activity, and rapid eye movement (REM), throughout which the brain is very active. Some scientists believe NREM sleep gives your body a break, and in turn conserves energy, similar to hibernation. REM rest could help to organize memories. Nevertheless, this concept isn’t proved, and dreams throughout REM rest don’t always correlate with memories.

 

Phantom Feelings:

It’s estimated that about 80 percent of amputees experience sensations, including warmth, itching, pressure and pain, coming from the missing limb. Individuals who experience this phenomenon, recognized as “phantom limb,” really feel sensations as if the missing limb had been part of their bodies. One explanation says that the nerves region where the limb severed create new connections to the spinal cord and continue to send signals towards the brain as when the missing limb was nevertheless there. Another possibility is that the mind is “hard-wired” to operate as if the system were fully intact-meaning the brain holds a blueprint of the system with all parts attached.

 

Mission Control:

Residing in the hypothalamus with the brain, the suprachiasmatic nucleus, or biological clock, programs the body to follow a 24-hour rhythm. The most evident effect of circadian rhythm may be the sleep-wake cycle, but the biological clock also impacts digestion, system temperature, blood stress, and hormone production. Researchers have found that light intensity can adjust the clock forward or backward by regulating the hormone melatonin. The latest debate is regardless of whether or not melatonin supplements could assist avoid jet lag-the drowsy, achy feeling you get when “jetting” across time zones.

 

Memory Lane:

Some experiences are hard to forget, like possibly your very first kiss. But how does a person hold onto these personal movies? Using brain-imaging methods, experts are unraveling the mechanism responsible for creating and storing memories. They’re finding how the hippocampus, within the brain’s gray matter, could act as a memory box. But this storage region isn’t so discriminatory. It turns out that both true and false memories activate similar brain regions. To pull out the real memory, some researchers ask a subject to recall the memory in context, some thing that’s much much more hard when the event didn’t really occur.

 

Brain Teaser:

Laughter is among the least understood of human behaviors. Experts have found that during a good laugh three parts of the brain light up: a thinking part that helps you get the joke, a movement area that tells your muscles to move, and an emotional region that elicits the “giddy” feeling. But it remains unknown why a single individual laughs at your brother’s foolish jokes while an additional chuckles whilst watching a horror movie. John Morreall, who is really a pioneer of humor research at the College of William and Mary, has discovered that laughter is a playful response to incongruities-stories that disobey conventional expectations. Others within the humor field point to laughter like a way of signaling to an additional person that this action is meant “in fun.” A single thing is clear: Laughter makes us feel much better.

 

Nature vs. Nurture:

Within the long-running battle of whether our thoughts and personalities are controlled by genes or environment, experts are building a convincing body of evidence that it could be either or both! The ability to study individual genes points to numerous human traits that we have little control over, yet in many realms, peer stress or upbringing may be shown heavily influence who we are and what we do.

 

Mortal Mystery:

Living forever is just for Hollywood. But why do humans age? You are born with a robust toolbox full of mechanisms to fight illness and injury, which you may believe should arm you against stiff joints and other ailments. But as we age, the body’s repair mechanisms get out of shape. In effect, your resilience to physical injury and stress declines. Theories for why people age could be divided into two categories:

1. Like other human characteristics, aging could just be a part of human genetics and is somehow beneficial.

2. Within the less optimistic view, aging has no purpose and results from cellular damage that occurs more than a person’s lifetime. A handful of researchers, nevertheless, believescience will ultimately delay aging at least long sufficient to double life spans.

 

Deep Freeze:

Living forever might not be a reality. But a pioneering field known as cryonics could give some individuals two lives. Cryonics centers like Alcor Life Extension Foundation, in Arizona, store posthumous bodies in vats filled with liquid nitrogen at bone-chilling temperatures of minus 320 degrees Fahrenheit. The idea is that a person who dies from a presently incurable disease might be thawed and revived in the future when a cure may be discovered. The system with the late baseball legend Ted Williams is stored in one of Alcor’s freezers. Like the other human Popsicles, Williams is positioned head down. That way, if there were ever a leak within the tank, the mind would stay submerged within the cold liquid. Not among the cryopreserved bodies has been revived, simply because that technology doesn’t exist. For a single, when the body is not thawed at exactly the right temperature, the person’s cells could turn to ice and blast into pieces.

 

Consciousness:

When you wake up in the morning, you might perceive how the Sun is just rising, hear a few birds chirping, and maybe even feel a flash of happiness as the fresh morning air hits your face. In other words, you’re conscious. This complex subject has plagued the scientific community since antiquity. Only recently Neuro-scientists have considered consciousness a realistic research subject. The greatest brainteaser in this field may be to explain how processes within the mind give rise to subjective experiences. So far, scientists have managed to develop a great list of questions.

  • this bothered me. I lost sleep and think a lot, and the next day I often stress. I want to change, I have to do now?
