Memory loss, language disorders and inattention in adulthood, symptoms of mild cognitive impairment (MCI) that can lead to Alzheimer's, are directly related to high blood cholesterol levels, according to a study that warns leads the Hospital Clínic de Barcelona.
Did you know that if we put all the neurons of an adult brain (100,000 million) in single file they would occupy approximately 1000 kilometers? And that the key to prejudice is also in our gray matter? Or that Henry Markram, director of the Blue Brain Project (BBP), assures that we will be able to build an artificial replica of the human brain within 10 years?
To celebrate Brain Week, in VERY Interesting we have rescued six very "brainy" interviews with Joseph Ledoux, Eve Marder, Helen Fisher, Steven Pinker, Joe Z. Tsien and Ferran Salmuri, who tell us how our thinking organ works.
The best antidote to cognitive decline and memory loss is learning. According to a study by the University of California, if we cultivate the mental activity of an "eternal learner" our brain produces molecules that keep it young and healthy.
Normally the body regulates its water content by balancing the intake of fluids (through thirst) and its elimination (through the production of urine). When the amount of water in the blood is low, cells called osmosensory order the release of vasopressin by the hypothalamus, an antidiuretic hormone that orders the body to retain as much fluid as possible.
Researchers from the California Institute of Technology (United States) and Trinity College, Dublin (Ireland) have found the first physiological evidence that the brain responds to inequality like a true "Robin Hood". The experiments, published today in the journal Nature, show that reward centers in the human brain respond more strongly when a "poor" person receives a financial reward than when a "rich" person does.
Where does intelligence reside? What makes us more or less intelligent than the rest? According to an American study in which the Spanish Roberto Colom, from the Autonomous University of Madrid, has also participated, general intelligence is based on effective communication between specific regions of both brain hemispheres.
A new study from the California University of Berkeley (USA) reveals that 90 minutes of naps serve to clear the mind and improve learning ability. The findings support the hypothesis that sleep is absolutely necessary to clear short-term memory and "make room" for new information, and could help understand the memory problems that accompany aging.
