John CraneBrain games will make you smarter! The internet is making you dumber! Alcohol is killing your brain cells! The brain is a mystery we've been trying to solve for ages, and the desire to unlock its secrets has led to vast amounts of misinformation. Many of these false notions are more widely believed than the truth. We took our healthy skepticism and a bunch of brain research to find the truth behind some of the most common myths about intelligence and our brains. Here's what we learned

In 1998, national magazine ads for U.S. Satellite Broadcasting showed a drawing of a brain. Under it was the caption, "You only use 11 percent of its potential." Well, they're a little closer than the ten-percent figure, but still off by about 89 percent. In July 1998, ABC television ran promotional spots for The Secret Lives of Men, one of their offerings for the fall season's lineup. The spot featured a full-screen blurb that read, "Men only use ten percent of their brains."
-
After that, champions of the paranormal used the 10% claim to explain the potential for psychic powers. It became fun to imagine the incredible potential available to us humans once we were able to unlock the remaining 90%.
-
Brain imaging studies using PET scans and functional MRI show that any mentally complex activity uses many areas of the brain, and over a day, just about all of the brain gets a workout. More proof that the entire brain is crucial for daily life is the devastating impact of damage to even a small area of the brain

While you can't look forward to developing incredible superpowers with the help of rapid evolution, or any other crazy theory, you can keep yourself healthier later in life by simply staying mentally active. You may not be able to bend metal with your mind, but at least you'll stay coherent in your golden years.

[T]he elaborate tapestry of our experience is not stored in memory-at least not in its entirety. Rather, it is compressed for storage by first being reduced to a few critical threads, such as a summary phrase ("Dinner was disappointing") or a small set of key features (tough steak, corked wine, snotty waiter). Later, when we want to remember our experience, our brains quickly reweave the tapestry by fabricating-not by actually retrieving-the bulk of the information that we experience as a memory. This fabrication happens so quickly and effortlessly that we have the illusion (as a good magician's audience always does) that the entire thing was in our heads the entire time.

Vicki DavisThis is a good summary of many of the brain and learning studies, although it is not written by a researcher or cognitive expert. I find the last one interesting, "believe you can get smarter" and it becomes possible. ;-)

people who did the brain training didn't do any better on the test after six weeks than people who had simply been on the Internet. On some sections of the test, the people who surfed the Net scored higher than those playing the games.

"33 British students were given IQ tests and brain scans at ages 12 to 16 and again about four years later by researchers at the Wellcome Trust Centre for Neuroimaging at University College London; 9% of the students showed a significant change of 15 points or more in IQ scores," reports the Journal. And these changes weren't just due to measuring errors. The MRIs showed changes in gray matter - which are linked to IQ

A chronic overreaction to stress overloads the brain with powerful hormones that are intended only for short-term duty in emergency situations. Their cumulative effect damages and kills brain cells.

Instead, as psychologist Dan Gilbert points out in his book Stumbling On Happiness, our brains record the seemingly necessary details and fill in the rest when it's time to remember:

Gilbert's conclusions come from memory researcher Daniel Schacter, who believes the construction of memory is very similar to the way we imagine the future:
We have argued in recently that memory plays a critical role in allowing individuals to imagine or simulate events that might occur in their personal futures. We have further suggested that understanding memory's role in future event simulation may be important for understanding the constructive nature of memory, because the former requires a system that allows flexible recombination of elements of past experience, which may also contribute to memory errors.

The reason we find it easy to believe the internet is making us dumber is because, in some ways, it's making us less self-reliant. Our GPS devices navigate for us and we neglect to remember things because we have Google search. That doesn't make us dumber, necessarily, but rather causes us to rely more on what psychologist Daniel Wagner calls transactive memory. This type of memory is actually very useful because it allows us to, in essence, store more data in less space.
-
-
-
When our access is cut off, suddenly we're bereft of our knowledge because our transactive memories are rendered useless. The reality is, without actual proof that the internet is making us dumber, so far it appears that the entire idea hinges on the evolving manner in which we interact with and access information as opposed to any sort of fact, making this more of a cultural claim than a scientific one.

If we only used 10% of our brains, what's the point of the other 90%?

However, we do have some brain reserves. An autopsy study found that seniors who stay mentally active-through activities like reading the paper, going to the theater, or playing chess-are less likely to develop Alzheimer's disease-even if they have the characteristic physical brain changes typical of dementia, suggesting that mental function has a "use it or lose it" component.
-
The proof comes from a 1993 study by Grethe Jensen that matched brain samples from both (deceased) alcoholics and non-alcoholics and found no difference in the density of brain cells.
-
What alcohol can and does do to your brain is affect the way your neurons get their firing triggers from glutamate. It infiltrates the glutamate receptors in your synapses, hurting their ability to send off their normal "fire" messages. Alcohol has this impact all across your brain—the parts that control muscles, speech, coordination, judgment, and so on. Keep that in mind the next time you or someone else claims that they drive, golf, or otherwise perform some task better with alcohol's help
