Your Brain Needs New Things

Brain training does more than just make you a better game player -– it also makes you better at the things you do every day. In order to accomplish this, effective brain training requires a number of critical elements, one of the most important of which is novelty.


When you play a brain game for the first time, you get a good mental workout from having to respond to the game’s central cognitive task. If the task stays the same, however, you will eventually develop cognitive strategies for solving that task. These strategies, in turn, will reduce the demands on your brain and thus the usefulness of the training. To keep the workout maximally effective, your brain needs novel challenges that circumvent any task-specific strategies. In this way, cognitive exercise resembles physical exercise: you have to “confuse” your mental muscles to build them up.

Lumosity.com solves the problem of novelty in two ways. First, individual games change and adapt over time in order to introduce new challenges. For example, in the game Face Memory Workout, the central cognitive task evolves over time. In some cases, you simply need to identify the face you just saw. In other cases, you have to identify the face you saw several turns ago. By changing the task demands, this exercise keeps your brain off balance, challenging your working memory in novel ways.


Second, Lumosity.com introduces novel challenges by exercising each of the major cognitive areas (speed, memory, attention, flexibility and problem solving) with a variety of games. Our training courses ensure your brain will encounter an endless supply of new and evolving tasks.

Lumosity.com has over 30 games to challenge your brain, so log in now to start your mental workout! Subscribe to Lumosity today and receive 25% off.

menstrual blood stem cells stroke
Signature Tune







Stem cells derived from menstrual blood are hitting the laboratory, with researchers speculating that a woman's period might be a boon for recovering stroke patients.

A collaboration between researchers at the University of South Florida, along with a stem cell company and a biotech firm, will investigate the efficacy of transplanted menstrual-blood-derived stem cells in repairing brain damage incurred by a stroke.

Blood vessels and neurons in the brain are both needed to help repair the brain after a stroke, and stem cells would spur the growth of both vital components.

In fact, research has already indicated that lab mice respond positively to the approach.

Not to mention that the stem cells are readily accessible, in relatively unlimited supply, and presumably easy to obtain -- although researchers didn't disclose exactly how they're being sourced.

This isn't the first time science has sought menstrual blood as a source of stem cells. In 2008, a team at Indiana University concluded that the stem cells could prevent limb amputations caused by peripheral artery disease.

And Michigan-based researchers in 2007 pinned down a specific type of menstrual stem cell that's capable of differentiating into more tissue types (from fat to muscle to nerve) than standard adult stem cells.


And given the ongoing debates over the use of embryonic stem cells in medical research, effective alternatives could fast-track new discoveries into the possibly widespread potential of stem cells in medical practice. Could a tampon-like kit for collecting menstrual blood expressly for the purpose of harvesting stem cells be far behind?

"Menstrual blood offers an adult stem cell alternative that circumvents the ethical and logistical limitations of embryonic stem cells," Dr. Cesar Borlongan, a neurologist at the University of South Florida, said in a statement. "And their retrieval offers greater ease, and with a wider window of opportunity for harvest than other adult stem cells."

Researchers are now prepping a new study, in an effort to better understand how the stem cells repair molecular and cellular damage in mice who've suffered a stroke.

work it out and challenge it mentally and physically



Three seniors are asked this question: What do a teddy bear, a Christmas stocking and a turkey have in common?

"You hug them!" said a former librarian.

But do you hug a turkey? prompted their questioner behind the table. She pauses.

"They all gobble?" said a 67-year-old man, grinning.

Welcome to The Brain Fitness Club. It's a window into a growing population in America: adults who are beginning to forget names, telephone numbers and how to drive home, but are aware enough to do something about it whether that's playing word-association games or bowling on a Nintendo Wii.

While there's no magic pill for dementia, or even "senior moments," scientists are converging on what makes a brain-healthy lifestyle. And it looks a lot like the Winter Park, Fla., class and the dozen other brain clubs that have popped up in Central Florida.

"There's no universal prescription that will solve everyone's brain problems," said Alvaro Fernandez, CEO of SharpBrains, a brain-fitness think tank. "But the good news is, there is a lot we can do."

Not too long ago, scientists believed we all start with roughly 3 trillion brain cells that, through careless decisions such as drinking alcohol and playing tackle football, we gradually kill off. Once a brain cell was lost, the brain was one man down, forever.

That's a myth, we now know.

The brain is a tangled web of cells that is constantly rewiring itself, like acrobats unlinking arms and swapping partners. The brain can grow new cells to link into its intricate network, tossing a new gymnast into the act.

In the last five years, scientists have unlocked the secret to manufacturing the precious cells involved in memory and recall, the ones that light up when digging for our best friend's name or our mother's address.

In experiments where mice were timed running through mazes or recalling patterns, the rodents that broke a sweat on a hamster wheel performed better. After slicing into their brains, scientists discovered why: The exercising mice had grown new brain cells.

"Exercise creates a stronger, faster brain," said Beverly Engel, program coordinator for the Alzheimer's Association in Central Florida. Patients with Parkinson's disease have regrown brain cells after just two months of physical exercise.

No one knows the perfect exercise formula for brain health - some experts say 30 to 60 minutes, three times a week - but simply walking has shown benefits.

"The more intense, the better," said Engel. "But doing anything is better than doing nothing."

The practices that harm our body also harm our brain. Stress kills neurons and prevents new ones from growing, and can lead to depression.

A depressed brain is fertile ground for Alzheimer's. The disease attacks faster in depressed patients, and it shows in the autopsy: depressed brains are riddled with brain plaque, or sticky buildup around brain cells, and tangled protein fibers.

"The best way to get Alzheimer's is to be at home, isolated," said Nancy Squillacioti, director of the Alzheimer Resource Center in Orlando, Fla.

It seems the happier you are, the more you hold on to your memory. In a 2008 study of 50- and 60-year-old adults with dementia, the most socially active were the best at remembering word lists.

Before sessions start at the Winter Park class, men and women are schmoozing and smiling as they shuffle to their chairs around a square meeting room. Laughter cuts above the ambient chatter.

"The most helpful thing about this class is, I get to socialize with people," said Tommy Roberts, 72, a retired veteran. "I wouldn't trade this for anything." A pause. "Except for my memory back!" he said.

Research solidly suggests that exercise and socialization can slow dementia. But there's less agreement on mental exercises, such as the brain-teaser games that are increasingly marketed to aging adults.
