OPINION: What’s physiology and psychiatry

I believe that medicine may provide more time, and it may relieve some of the symptoms. My friend doctor, Nawar Kbibou, said that medicine bring the people to a level at which they could be talked to.

Brain Networks linked to human intelligence

“Our research suggests that it might be possible to work with these genes to modify intelligence, but that is only a theoretical possibility at the moment – we have just taken a first step along that road.” “Traits such as intelligence are governed by large groups of genes working together – like a football team… Continue reading Brain Networks linked to human intelligence

Why do we sleep?

As I often find myself lacking the time, or the energy, to study complex topics in Mathematics or Biology, I choose to spend three hours working in the afternoon and then go to sleep at ten o’clock. Therefore I would be able to wake up the next day at five o’clock in the morning and study one or two more hours before courses start. This would give me about six hours and a half of sleep (taking into account that I don’t fall asleep right away).

Russell Foster is a circadian neuroscientist: He studies the sleep cycles of the brain. And he asks: What do we know about sleep? Not a lot, it turns out, for something we do with one-third of our lives. In this talk, Foster shares three popular theories about why we sleep, busts some myths about how much sleep we need at different ages — and hints at some bold new uses of sleep as a predictor of mental health (http://www.ted.com/talks/russell_foster_why_do_we_sleep#t-592084).

This 21 minutes video of Dr. Russell reveals some pretty interesting discoveries neuroscientists have recently made.

The New World Order – Preparing for what ought to come

At the end of 2012 people all across the world went mad about the mayan calendar and how the world will come to an end. As I know, and as you know, this wasn’t the first time “humans” have out-lived their end. Leave the fairy tales about the mayan calendar behind, we get a much clearer… Continue reading The New World Order – Preparing for what ought to come

Extreme Sports, Featuring Bike Trials

          Strong hearted people who aren’t having enough fun just by doing normal sports, go for the extreme, make a sport of it, and get their adrenal gland secrete as many hormones as possible. Those kind of sports remain a simple hobby for some, but for others they become a way of life, or even a source of money.  

 It is mad to think that people go out there and have fun by risking their lives, or while risking their life. By simply attempting extreme sports we go against our human nature, that is avoiding danger in order to survive. Therefore who are those people that involve themselves in dangerous activities? A study of 15 participants showed that a bungee jumper might for example feel a certain rush of immortality and his may lead to psychological effects that have positive effects for life in general (Isaksen, The Psychology of Extreme sports).  

          One of these crazy sports is Bike Trials, which is relatively new compared to the many others. It is a sport that has to do with extreme biking. The rider has to mount a specially made bike (it has no sit, and wheels larger than normal), and perform tricks which require both physical and mental strength. Many of the tricks require the rider to maintain the bike at equilibrium on the rear wheel, position from which he can jump forwards over, or on, an obstacle. Trials riding is an extreme real life test of bicycle handling skills over either natural or man-made obstacles. 

          Despite feeling fear, a mechanism set to protect us if we were to run over something dangerous, many people seem to confront it without showing any problems. Oh but already spoiled the fact that they can actually feel fear, and now I can’t ask you anymore if they feel fear. But I can still ask you “Why do you think that they have no problem in confronting fear?” 

The answer lays within our brain, and it is also part of the same defence mechanism. For every single time we feel fear, and manage to survive…, this mechanism repays us with dopamine. Dopamine is the hormone that gives us the sensation of pleasure, so by secreting this hormone the body learns that by continuing to survive, it will be rewarded. 

This is why it is natural to hear people saying they are addicted to extreme sports. The next time you hear people saying that one is practicing extreme sports because one is addicted to danger correct them. One is not addicted to danger, but to a biochemical secreted by the body, in the blood, as a result of one’s survival. One is not addicted to danger, but to living.
