One of the most consistent ways research has demonstrated to increase connectivity in the brain is to learn new physical skills. Controlling the body in space

One of the most consistent ways research has demonstrated to increase connectivity in the brain is to learn new physical skills. Controlling the body in space appears to be particularly good at stimulating the growth of new synapses (and possibly new neurons as well, though the research is not conclusive here outside the hippocampus). Yoga is a good start. Modern dance, breakdancing, capoeira and gymnastics are all excellent if you're slightly more athletic. Beyond that, practicing thinking in different ways really helps your brain develop. One thing that most people neglect is geometric/mechanical intelligence. Get some 3D puzzles, and once you get really good at them, start building simple machines. If you never got good at math, trying to pick up some advanced mathematics can be a good exercise as well.

To what extent is that connectivity valuable beyond physical exercise? Is there good evidence that this does more than improve coordination and proprioception? (Obviously coordination and proprioception are valuable, but people who value them likely don't need convincing of the merits of exercise!)

  I think that _initially_ this new neural growth can be co-opted into general mental flexibility, particularly for things like mathematics and visual reasoning. In a sense, varied movement makes you more aware/perceptive of space. However, I think over time if you don't try to utilize your increased spatial awareness to solve spatial problems, eventually those new neurons will prune their synaptic connections to make the network as efficient as possible. Thus, I believe that pairing novel mental and physical training is the best bet for improving overall intellectual abilities.

  Short answer: yes, physical exercise has been scientifically proven to improve cognition (working memory, attention, and other factors). In addition to physical exercise, the two other things the author neglects to mention (though it might not be as relevant for her population, comprised of children) are diet and stress relief.

The more literature I read about this, the more compelling I find this. In mammals, the larger the body the larger the brain. That's because you need all those neurons to control all those muscles. I recently read some papers that hypothesize the muscle atrophy we experience as we get older is partially the result of the neurons controlling those muscle-fibers dying [1]. As infants, our brains grow into our bodies by producing more neurons than we need and then killing off the neurons that aren't being used [2]. It makes sense to me that if we don't use our bodies in a variety of exercises, the lack of signal from the muscles to the brain could result in pruning those neurons as we get older.

  Is an elephant really more intelligent than a human then?
  - jventura 10y ago
    I think he's not talking about intelligence, but about muscle control which kind of makes sense..

    No, an elephant needs a larger brain to run its larger body. Humans have enough brains to run our bodies, plus "extra" with which to think, in a manner of speaking. https://en.wikipedia.org/wiki/Encephalization_quotient https://en.wikipedia.org/wiki/Encephalization_quotient

      I've always thought the metabolic needs must have been just as driving (specifically, being carnivores).

Juggling is also good for growth in both gray matter and white matter.

I used to do boxing earlier in college, and used to hit the gym religiously till last year, when my elbow fractured and got implants to hold it together. After that I wasn't able to do much activity, even if I wanted, apart from running. Even pushups carry a risk of screwing up the implants in my elbow. What kind of physical activity do you think can be done in this type of scenario?
- unusximmortalis 10y ago
  Swimming (try also cold water not pools). QiGong
- cableshaft 10y ago
  Maybe swimming? Possibly tennis or racquetball if you only use your other arm to hold the racquet. I'm not sure how easy it is to screw it up again, but if you can still handle running it seems like those two might be okay.

  Tai Chi
- warfangle 10y ago
  Pilates could be very useful. Most of it is very low impact strength training - instead of holding up your body weight, you're straining against springs, for example. There are a lot of exercises that don't focus on the arms because Pilates focuses on very discrete muscle groups for each exercise. I wouldn't start with group classes, though: talk with your physical therapist (are you doing PT to help the recovery?) about appropriate exercises, and maybe sign up for a few introductory private pilates classes. Be sure to inform the instructor about the limitations you have.
- kej 10y ago
  Some kind of casual low-impact sport (or at least low-bad-arm-impact), like pick-up soccer or disc golf. That way you'd still be getting the movement and coordination practice that you don't necessarily get from running. Also bicycling might give you the same benefits from running but with more new things to take in.

Why arent athletes the most intelligent then? Generally in society there is considered a negative correletion between people that exercise/play a ton of sports and intelligence. Whether this is true or not is up to debate, but stereotypes exist for a reason...

  I think most professional athletes are highly intelligent, but some never learned to apply it to anything other than sport. Watch Kobe or LeBron on the court. There is an incredible awareness of the shifting context of the game and the available moves. In the greatest athletes it is faster and more fluid than in most athletes. It's a constantly shifting analytical mode that leans heavily on training and instinct, but is full of novelty. Consider that opponents spend weeks watching tape in hopes of understanding how to anticipate what Kobe will do. In terms of physical metrics (size, speed, etc.) professional athletes are pretty close to average. I think it is a combination of intellect and general desire to win that makes some people become great athletes. Because of what I like to call Cartesian Blindness (viewing the world through the mind/body duality) we assume it's simply a matter of great athletes having superior muscle fibers, etc.
  - kornish 10y ago
    Do you have a source for your statement that professional athletes are pretty close to average in "physical metrics"? By most accounts, there's been a recent Cambrian explosion in college and professional sports where larger pools of participants has resulted in a higher frequency of genetic outliers gravitating towards the sport for which their body is best suited. David Epstein's "The Sports Gene" covers this topic with some depth. Many people are brilliant, talented, and have a strong desire to win but lack the physical aptitude to support that at elite levels of play.

How would one get into 3D puzzles and simple machines/mechanics? I suppose IoT or Arduino could get you part of the way there but that's still very software-based.
- CuriouslyC 10y ago
  You can buy puzzle cubes, they're made up of irregular blocks that need to be assembled in a certain way to hold together. The only downside to these is that after you "learn" how to put it together by assembling it a few times, it doesn't do much for you, though I suppose you could up the challenge by assembling it blindfolded. Field stripping and reassembling guns is a good practical entry to mechanics. Again, after you've done it a few times it doesn't really teach you anything new, but the blindfold trick would work well here too. Lego robots are another good basic intro into mechanical intelligence. You can graduate from them to DIY robotics kits.

- yoha 10y ago
  Rubik's Cube. Try solving it yourself for a while (a few months/years). You will probably not completely solve it, but even solving one face, trying to solve a second one, trying to complete rings instead, etc, should get you to experiment and use new thinking models.
