If you bump your head, your brain will bump against the inside of the skull, which will put pressure on it. All nerve cells are sensitive to pressure, including the optic nerves, and give nerve signals when there is pressure. The blow you get triggers a number of random vision-related nerves that are perceived as dots of light.
MEN VS. WOMEN Male brain is larger than female brain WHERE: The men win by weight. In 2014, British researchers measured thousands of brains and found that men's are on average 8-13 percent larger than women's. But the female brain has better internal communication.
1. They are specially designed for you © Shutterstock Your nightmares are precisely tailored to what scares you. As a result, your nightmares can be very ordinary dreams for someone else. It may be that you do not understand what someone is talking about when he talks about his nightmares.
The magnets of the scanner make a hell of a noise, which there is no escape for the war veteran who lies with his head in the tube. He must grind his teeth in pain - but not because of the sound. When the young man was on a mission two years earlier, he was shot in the thigh, and afterwards the pain became chronic.
Take a look at these almonds, which are in a certain pattern. Can you leave them still? Oh no? The image most closely resembles a moving animation, but it is really a still image. The movement is caused because your eyes bake you a brush. Your eyes wander constantly to ensure that you see as much as possible and to follow all movements in your field of vision.
The Irish railway worker Phineas Gage was known as a gentle, thoughtful man. 25-year-old Gage led a team in the northeast of the USA that blew up pieces of rock to make way for the rails. When his colleagues drilled holes in the rock and filled them with explosives, Gage stamped sand and gravel on the blasting charges with a long, iron rod to enhance the effect.
Although glial cells make up 70 percent of brain cells, we can still be surprised by the way they function. Now neurologists have succeeded for the first time in seeing how a certain type of glial cells, microglial cells, works. Nerve cells ask for help A team of researchers from the European Molecular Biology Laboratory in Rome and in Heidelberg made microscopies of the interaction of these cells with the nerve cells.
Under our large brain are the fist-sized small brain, which was previously only regarded as the motor center. But now it has been discovered that they have many more important functions. In this way they ensure that we like to be with others. It was already known that the small brain may play a role in schizophrenia and autism, which impede social behavior. Small brains are connected to reward center American researchers therefore examined how the small brain is connected to other areas of the brain.
The length and thickness of the foothills of brain cells, dendrites, determine our intelligence. This has emerged from new research from the VU and Amsterdam UMC. Dendrites are the offshoots that bring a nerve cell into contact with other nerve cells. The team examined the dendrites of the nerve cells of 46 patients who underwent brain surgery as part of the treatment of epilepsy or brain cancer.
Two areas in the brain together are responsible for our free will, new research shows. Scientifically speaking, free will is the interplay between intentions and actions. When you perform an action, it requires that you decide to do the action and that you are aware that you are doing it.
The enemy has crossed your border without even realizing it. And now you are here, face to face with a trained killer who is already working hard to destroy the rest of your stronghold. Fortunately, you know the strategy - you have seen your rival before and know exactly what counterattack is needed to get it out of your system this time.
The neurologist Constantin von Economo is puzzled. Thoughtfully, he strokes his full, black mustache, examining his eyes on the patient who appears in his practice in January 1917 in the Austrian capital, Vienna. The man is clearly very ill, but his symptoms are strange and do not resemble the symptoms that Constantin von Economo normally observes in his clinic.
You can now have a mini-copy of your brain grown in a Petri dish, complete with nerve cells and blood vessels. With a little luck, these brains also develop the early stages of eyes. Scientists have been experimenting with artificial brains since 2013, but only recently have they succeeded in having these brains develop their own blood vessels.
Depression is one of the most common mental illnesses. Research suggests that one in six people develop symptoms of depression over the course of life. Fortunately, something can be done about it now. Scientists have discovered that the state of mind of depressed people improves when a certain area of the brain is energized.
1. Sleep enough © Shutterstock Sleep is essential for your brain. While you are in dreamland, important connections are strengthened and new ones are added, and waste is cleaned up. In 2014, American researchers demonstrated that your brain can shrink due to lack of sleep - especially the front lobe, which are important for concentration, memory and problem solving, among other things.
Take a good look at the image above. What kind of lines do you see? Bent, straight or both? The reality is that all lines are the same. They are all equally wavy. The difference is that the light and dark parts of the lines are placed differently. Most people notice that every other pair of lines is angular and zigzagging.
This means the IQ: 130 or more: gifted. 3% of the population has an IQ of 130 or more. Between 85 and 115: normal. 68% of people have a normal IQ. 70 or less: gifted. Less than 3% score 70 or less. You can test your own IQ with our large IQ test. IQ 280 William James Sidis (1898-1944).
'If you sit on a hot stove for a minute, it seems to take an hour. But if you talk to a beautiful girl for an hour, it feels like a minute. " This quote from Albert Einstein indicates that the experience of time is very subjective and dependent on the situation. Norwegian researchers from the Kavli Institute for Systems Neuroscience Center are now finding out why.
Patients with fibromyalgia disease often have severe pain with no known cause. Now, however, Swedish and American researchers are tracking the development of the disease. Fibromyalgia is characterized by chronic pain in many places in the body, concentration problems, fatigue and headache.
The midwife had good news for the young parents, and he could answer their frightened look with a smile. 'Your son is doing fine. I have done all the physical exams and there is nothing wrong with him. Congratulations, enjoy him. " The doctor took a few steps to the door, but turned and spoke.
Alcohol increases the activity of the signal substance GABA, which dampens a number of nerve signals from the brain. In addition, the neurotransmitter glutamate, which stimulates the nerve signals, is inhibited. The result is that the brain rotates at idle speed and they control the muscles with a delay. As a result, someone who is drunk cannot adjust their center of gravity and the body quickly becomes unbalanced.
