Animals with large brains are smarter, but they have fewer offspring and smaller intestines. This fact, which has been suspected for a long time, has just been experimentally confirmed in guppy fish (Poecilia reticulata) by an international team of researchers who publish their work in Science.
When we perform a task many times, we end up automating it by starting what we call subconscious perception. It is something completely normal and necessary for life, but what happens when we drive or carry out a task that may involve a certain danger? We analyze what is subconscious driving.
In the last decade, several studies have analyzed the effects of meditation on our brain, but also on the heart, on the immune system, when it comes to fighting pain and even against insomnia. These are some of the most relevant conclusions.
A team of scientists, led by researchers from the Karolinska Institute in Sweden, has discovered that the olfactory bulb of humans - a structure of the vertebrate brain that processes sensory input from the nose - is distinguished from that of all other mammals in that, after being born, new neurons no longer develop in it. This fact could be the reason that humans lack a sense of smell as acute as that of animals.
The same neurons that control appetite are also related to the search for novelty and the attraction to drugs, according to a study published in the journal Nature Neuroscience. Until now, scientists have studied the brain's reward circuits thinking that, in patients with obesity and diabetes, food has the same effects as the abuse of drugs such as cocaine. However, the latest study, conducted by researchers at Yale University, seems to indicate otherwise.
A British study published in the journal Current Biology suggests that the brain of London taxi drivers changes as they learn to navigate the 25,000 streets of the city and identify the destinations most requested by tourists and businessmen, usually from three or four years at the wheel.
Jonathan Swift tells in "Gulliver's Travels" that in the Great Lagado Academy, located in the imaginary country of Lapot, the students remembered the mathematical formulas by writing them with a special ink on wafers and then devouring them on an empty stomach. Although in real life memorizing is not so easy, we suggest some simple techniques to improve your retention.
Scientists from the University of Florida (USA) and Shanghai Fudan University (China) have shown that adults who practice Tai Chi three times a week have greater brain volume and better results in memory and reasoning tests. The results are published in the 'Journal of Alzheimer's Disease'.
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.
