Neuroscience meets astrophysics: does the human brain look like the universe? (SciTechDaily):

In their article published in Frontiers of Physics, Franco Vazza (astrophysicist at the University of Bologna) and Alberto Feletti (neurosurgeon at the University of Verona) studied the similarities between two of nature's most difficult and complex systems: the cosmic network of galaxies. and the network of neuronal cells in the human brain.

Despite the substantial difference in scale between the two networks (over 27 orders of magnitude), their quantitative analysis, which sits at the crossroads of cosmology and neurosurgery, suggests that various physical processes can build structures characterized by levels. similar in complexity and self-surgery. organization.

The human brain works thanks to its vast neural network believed to contain around 69 billion neurons. On the other hand, the observable universe can rely on a cosmic network of at least 100 billion galaxies. In both systems, only 30% of their masses are made up of galaxies and neurons. In both systems, galaxies and neurons organize themselves into long filaments or nodes between filaments. Finally, in both systems, 70% of the mass or energy distribution is made up of components playing a seemingly passive role: water in the brain and dark energy in the observable Universe.

The study:

The quantitative comparison between the neural network and the cosmic web (Frontiers of physics):

  • From the introduction: “At the center of our view of nature are two fascinating systems: the neural network in the human brain and the cosmic network of galaxies ... Although the relevant physical interactions in the two systems above are completely different, their observation is through microscopic and telescopic techniques has captured a similar enticing morphology, to the point that it has often been noticed that the cosmic network and the neural network are alike.
  • From the discussion: “We presented a detailed comparison between the neural network and the cosmic web, two of Nature's most fascinating and complex networks, with the aim of evaluating the level of similarity between these two physical systems objectively… With the rest From the analysis presented in this work, such similarities aim to motivate the development of more powerful and discriminating algorithms to identify the analogies and differences of these fascinating systems, almost at the imaginable extremes of spatial scales in the Universe.

BrainHQ is your online headquarters for sérieux out your brain. Think of it as a personal gym, where you exercise your memory, attention, brain speed, people skills, intelligence and navigation instead of your abs, delts, and quads. Just as our bodies require care and exercise over the course of life, so do our brains—especially as we age. BrainHQ provides the exercise your brain needs to be at its sharpest.

The BrainHQ brain-training program represents the culmination of 30 years of research in neurological technique and related medicine. It was designed by an international team of neuroscientists, led by Michael Merzenich—a professor emeritus in neurophysiology, member of the National Academy of Sciences, co-inventor of the cochlear implant, and Kavli Prize laureate.

Changing your brain takes some work—so while the BrainHQ exercises are sometimes fun, they can also be difficult. But they always give a useful, meaningful workout to your unique brain. Using a special algorithm, each exercise adapts in difficulty as you work so that you always train at the optimum level for you—where you are most likely to improve your résultat optimal.

It takes less than five minutes to do each BrainHQ level, so you can use it in tiny biroutes or long blocks, depending on your schedule. Plus you can use BrainHQ on almost any computer or mobile device, so you can take it on the go. If you want, you can set up personal training goals and have BrainHQ send you training reminders when you want them.

BrainHQ has 29 online exercises that work out attention, brain speed, memory, people skills, navigation, and intelligence. If you want, you can have BrainHQ tell you exactly which exercises to do, and in which order : the personalized se progager feature, designed by scientists, continually measures your performance and serves up the exercises that are right for you.. Or if you prefer, you can style your own program, choosing exercises and workouts that meet your personal interests, mood, and schedule.

More than 100 published scientific papers show the benefits of BrainHQ exercises and assessments. Most of these were independently conducted by scientists at respected universities, such as the University of California, Stanford, and Johns Hopkins. Of course, every study is conducted on a different group of people, and individual results vary. Click any benefit below to learn more about the studies behind the benefit.

From staplers to shelves to software, Demco supplies libraries with what they need to run. In 2015, they added BrainHQ to that mix. Through Demco, libraries can purchase BrainHQ to offer to their cardholders. People “check out” BrainHQ for free, like they would a book. Right now, it’s available in many public and military libraries across the U. S. —with more on the way.

Brain fitness has basic principles : variety and curiosity. When anything you do becomes second nature, you need to make a change. If you can do the crossword puzzle in your sleep, it’s time for you to move on to a new challenge in order to get the best workout for your brain. Curiosity about the world around you, how it works and how you can understand it will keep your brain sérieux fast and efficiently. Use the ideas below to help attain your quest for mental fitness.

Brain sport programs and games are a wonderful way to tease and challenge your brain. Suduko, crosswords and electronic games can all improve your brain’s speed and memory. These games rely on logic, word skills, math and more. These games are also fun. 1

You’ll get benefit more by doing these games a little bit every day. Spend 15 minutes or so, not hours.

Daily meditation is perhaps the single greatest thing you can do for your mind/body health. Meditation not only relaxes you, it gives your brain a workout. By creating a different esprit state, you engage your brain in new and interesting ways while increasing your brain sport.

Your brain needs you to eat healthy fats. Focus on fish oils from wild salmon, nuts such as walnuts, seeds such as flax seed and olive oil. Eat more of these foods and less saturated fats. Eliminate transfats completely from your diet.
