As a general rule, we feel safe if people are located at a minimum distance of 20 to 40 centimeters away from our face, which are the physical limits of the peripersonal space, that is, the invisible area that surrounds us and that represents the margin of security between our body and the rest of the world.
The “high” produced by jumping into the void from a plane with a parachute on your back is due to the secretion of dopamine, a neurotransmitter linked to pleasure that, normally, leaves us wanting to repeat the experience. Faced with the physical "danger" to which we are subjected while practicing extreme sports, adrenaline or epinephrine is also secreted which, in addition to accelerating the heart, accentuates the senses and dilates the pupils so that more light enters through the eyes.
Teresa Belta and Esther Priyadharshini, from the University of East Anglia (UK), have shown that being always busy, especially during childhood, prevents the development of the imagination. On the contrary, being bored and doing nothing is positive for the brain. While we contemplate the shrews and remain unoccupied, neural circuits are activated that form the so-called "default network", discovered in 2011 by Raichel and Shculman.
Mood largely depends on the color of the light we keep on at night, according to a study just published in The Journal of Neuroscience. Thus, blue light is the one that most negatively affects mood, followed by white light.
Neuroscientists at the Massachusetts Institute of Technology (MIT), in the United States, have shown that it is possible to implant false memories in the brain of mice, and that many of the neurological traces of these memories are identical in nature to that of authentic memory.
That's how it is. Mark Lyte, from Texas Technological University (USA), has shown that after ingesting small doses of Campylobacter jejuni, one of the bacteria that causes the most food poisoning in the world, anxiety levels increase in the brain. To this is added that certain gastrointestinal bacteria that colonize the small intestine just after birth, and then accompany us throughout life, increase anxiety and fear, as well as sensitivity to stress, as Jane Foster has proven, from McMaster University (Canada).
A person who speaks a language regularly will use an average of 30,000 words. How do we manage to learn them, associate them and manage to communicate with others? A recent study has shown that language learning depends on the connection between regions of the left hemisphere of the brain.
A study from the University College of London, in the United Kingdom, has linked the lack of sleep in young children with a worse development of their cognitive abilities. The researchers analyzed the nocturnal habits of 12,000 children between 3 and 7 years old and analyzed their reading comprehension, mathematics and their spatial skills.
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
