Color and The Brain

During the holidays, the color red is everywhere we look, from bulbs and bows to Santa’s trademark threads.

What impact does this favorite holiday hue have on your brain?

For starters, studies show that the color red increases appetite (no wonder holiday goodies are so hard to resist!). Also, when people are exposed to the color red, tests show they become more cautious and attentive to detail, and memory skills improve as well.

In one study, more than 600 people were asked to perform various tasks, usually on a computer. When tasks (such as proofreading) required focus, people performed as much as 31 percent better when their computer screen had a red background.

In contrast, researchers say the color red can keep us from performing our best in situations where creativity and analytical thinking are required. For these tasks, people perform better after being exposed to the colors green and blue. Read the rest of this entry »

Shopping and the Brain

Three Simple Tips to Avoid Impulse Spending and Stay within Your Holiday Budget

The holidays are here, which for most of us means spending time shopping in malls or online looking for gifts for loved ones (and even for ourselves!). It also means trying to keep from spending too much money.

Apparently whether we stay within our holiday shopping budget may not depend as much on willpower as it does on the circuitry of our own brains.

Brian Knutson of Standford University and colleagues mapped the brains of shoppers using a MRI. They discovered that, as people contemplated whether or not to make a purchase, one of two segments of their brains would “light up.” If the nucleus accumbens–part of the reward and pleasure center of the brain–lit up, the subject would invariably make the purchase. If the insula–the part of the brain that registers pain (such as the pain of something costing more than its perceived value)–lit up, the subject would invaribly say “Thanks, but no thanks.”

By watching which part of the brain became active, researchers could accurately predict whether or not the shopper would make the purchase.

The reason shopping feels so good may be related to the brain chemical dopamine. This “feel good” chemical is released anytime we are exposed to the exciting mix of new places, challenges, sights and sounds–all of which are plentiful at the mall. Read the rest of this entry »

Jet Lag

Chronic jet lag shrinks your brain, making learning and remembering more difficult for up to a month after you return home!

So says a team of psychologists from the University of California, Berkeley. The researchers based their findings on a four week study of jet-lagged hamsters. The psychologists weren’t surprised to discover that the hamsters had trouble learning and remembering simple tasks while jet lagged. What surprised the scientists, however, was that the memory and learning deficit lasted an entire month after the critters had been returned to their regular programming.

The answer, they say, seems to lie in the hippocampus, a part of the brain used for processing memory. Even though the brain is constantly creating new neurons, after a month of jet-lag, the hamsters had only half the number of new neurons in the hippocampus region as non-jet-lagged rodents in the study’s control group.

Another study, conducted by Dr. Cho Kwangwook of the University of Bristol Medical School, revealed similar findings. Based on a study of flight attendants, Dr. Kwangwook concluded that chronic jet lag shrinks the frontal portion of the brain, resulting in temporary loss of memory and cognitive skills.

Brain Food

Teenage Girl Balancing Apple on her headDid you know that eating a potato can calm you down? Or that nutmeg and cinnamon can cause feelings of euphoria? Amino acids and other natural compounds are able to steer our mood swings. Nutrients can stimulate different regions of the brain and release chemicals that enhance brain activity or protect the brain from aging.

A specialist in Alzheimer’s disease, and a professor from Ohio State University, Gary Wenk started delving into the medicinal impact of food while studying how natural plants could impact memory.

People from the Indian subcontinent, he found, are much less likely to develop Alzheimer’s. The reason? They scarf down a lot of curry, which contains an antioxidant that keeps brain cells from aging.

For more about your brain on curry, and lots of other fascinating stuff, check out this article from the New York Post!

stroke recovery

stroke recoveryThink LearningRx is just for kids? Virginia Romero, from Shreveport, LA is 82 years old.  She had a stroke and lost some of her abilities.  She couldn’t remember where she lived or how old she was – so she called LearningRx in Shreveport to see if they could help. The following video is proof.  She is self-confident, enjoying novels, and beating the other ladies at cards. In her own words “…everything moves better and faster than it did before…when I read, I understand and retain more than what I did before… the main thing, I think, for me is, that it gave me hope that I’m not really at the end of my life. I’m 82 years old, but I’m still not ready to go and just give up. I’m still looking forward to new things, and LearningRx has certainly played a big, big part in that.”

rat brain robot

rat brain robotScientists in England have done something that makes all the science fiction you’ve ever watched or read seem suddenly plausible. They’ve taken brain cells (neurons) from the brain of a rat, and put them in a bell jar. Creepy enough already, but just wait. They also made a little robot, with sensors that “speak” to the rat’s brain via bluetooth. The data the sensors collect is transmitted to the actual brain. In the bell jar. Then, the brain (in the bell jar) sends commands back to the robot’s wheels. Yes. In this way, the disembodied rat brain actually learns, and, using its robot body, figures out how to avoid walls and scamper about like a normal rat. The most amazing part? Since the brain cells only live for about 3 months, they’ve used several different rats. And guess what? The robot behaved differently with every change. This is a real, live, rat cyborg. Now you’ve officially seen everything (let’s hope!) Watch the video, it’s totally creepy and amazing.

Increase Your Brain Power

increase-your-brain-powerSeems like everybody these days wants to increase their brain power. Take a trip around the web, and you’ll see what I mean. Some people say the best way to increase your brain power is to eat protein in the morning. Others say it has to do with exercise. For others, meditation is the answer to making the brain function at its best. All of these techniques are useful if we are talking about a qualitative increase, that is, getting the brain you have today to work at its best.  But what about quantitative increase? Can you make the brain you have today a bigger, better brain tomorrow? That would be an entirely different kind of increase in brain power!  There are many ideas out there for improving your brain’s health and function – but LearningRx goes a step further: our mission is to increase your brain power by growing the brain itself, and encouraging it to making new connections. Instead of just a healthy brain, you’ll have more brains! It’s the difference between having one healthy child, and having twins. Read the rest of this entry »

tv and the brain

tv and the brainMy sixth grade teacher, Mr. Muir, was brilliant. He was kind, and funny, and encouraging, and he knew how to inspire even the most stubborn of his students (like me) to really care about learning. He had this thing in the classroom called the “what-is-it” of the week. It was a random weird item we’d never seen before. We’d have to figure it out what it was and guess at the end of each week, for a prize. There was also the “where-is-it” of the week, which was usually a photo of a place we’d never seen.

These things really stirred our imaginations. He was forever having us constructing things, sculpting things, writing stories… I remember being outside in the courtyard one spring, hammering away at a birdhouse. He was untiring in his zeal for teaching, and for his students. And I worked hard for him because I respected him. Mr. Muir also had a saying that I’ll never forget. He was known to randomly proclaim it in the middle of a lesson about something completely unrelated. That saying was… Read the rest of this entry »

Sometimes, a small change can affect life in a big way. Motor oil, for example. Put good motor oil in your car, and all the parts run more smoothly. Or, increase the speed of your hard drive and watch how much more efficiently all your programs run. Or raise your brain’s IQ and see how your overall physical health improves.
