If you play a video game such as the new prototype game, Neuro Racer, will your brain begin to act as if it were younger again? See, "Video Game Sharpens Aging Brains - Technology News." Also you may wish to read the New York Times article, "A multitasking video game makes old brains act younger."
"The finding is a powerful example of how plastic the older brain is," says Adam Gazzaley, M.D., Ph.D., UCSF associate professor of neurology, physiology and psychiatry and director of the Neuroscience Imaging Center. Gazzaley co-founded the company, Akili Interactive Labs, which is developing the next generation of the video game, according to the September 4, 2013 UCSF news release, "Training the older brain in 3-D: Video game enhances cognitive control."
Dr. Adam Gazzaley, MD, PhD researches in the Gazzaley lab which is a cognitive neuroscience research lab at the University of California, San Francisco focused on studying the neural mechanisms of memory and attention, how these processes change with normal aging and dementia, and how we might intervene therapeutically to alleviate memory and attention deficits.
The lab utilizes state of the art techniques and analytical approaches to address its scientific and clinical goals by coupling behavioral assessments, functional magnetic resonance imaging (fMRI), electroencephalography (EEG) and transcranial magnetic stimulation (TMS). See, "Training the Older Brain in 3-D: Video Game Enhances Cognitive Control."
Gazzaley, who has made a career out of studying how distraction affects cognitive performance, says in the news release that his game, NeuroRacer, does more than any ordinary game – be it bridge, a crossword puzzle, or an off-the-shelf video game – to condition the brain. Like a good teacher, he said, NeuroRacer undermines people’s natural tendency to go on automatic pilot once they’ve mastered a skill, and pushes them further than they think they can go.
Video game training enhances cognitive control in older adults. A new study reveals plasticity in age-related cognitive decline, says the September 4, 2013 news release from the University of California, San Francisco, "Training the older brain in 3-D: Video game enhances cognitive control." Scientists at the University of California - San Francisco (UCSF) are reporting that they have found a way to reverse some of the negative effects of aging on the brain, using a video game designed to improve cognitive control. The new study trains older brains with 3-D video games that enhance cognitive control.
“Normally, when you get better at something, it gets easier,” he explains in the news release. But with this game, “when you get better, it gets harder.”
The findings of the latest study, published on Sept. 5, 2013 in Nature, show that a specially designed 3-D video game can improve cognitive performance in healthy older adults, they explain, according to the September 4, 2013 UCSF news services, "Training the Older Brain in 3-D: Video Game Enhances Cognitive Control." Check out the study in the journal Nature, "Training the older brain in 3-D: Video game enhances cognitive control." Or see the Nature article, "Gaming Improves Multitasking Skills."
The researchers said the study provides a measure of scientific support to the burgeoning field of brain fitness, which has been criticized for lacking evidence that such training can induce lasting and meaningful changes.

Scientists at UC San Francisco are reporting that they have found a way to reverse some of the negative effects of aging on the brain, using a video game designed to improve cognitive control, according to the September 5, 2013 New York Times news article by Matt Richtel, "A Multitasking Video Game Makes Old Brains Act Younger."
In the game, which was developed by the University of California, San Francisco (UCSF) researchers, participants race a car around a winding track while a variety of road signs pop up. Drivers are instructed to keep an eye out for a specific type of sign, while ignoring all the rest, and to press a button whenever that particular sign appears.

The findings, published this week in Nature, show how a specially designed 3-D video game can improve cognitive performance in healthy older adults
The researchers said it provides a measure of scientific support to the burgeoning field of brain fitness, which has been criticized for lacking evidence that such training can induce lasting and meaningful changes. In the game, which was developed by the UCSF researchers, participants race a car around a winding track while a variety of road signs pop up.
Drivers are instructed to keep an eye out for a specific type of sign, while ignoring all the rest, and to press a button whenever that particular sign appears. The need to switch rapidly from driving to responding to the signs, for example, multitasking – generates interference in the brain that undermines performance. The researchers found that this interference increases dramatically across the adult lifespan.
After receiving just 12 hours of training on the game, spread over a month, the 60- to 85-year-old study participants improved their performance until it surpassed that of 20-somethings who played the game for the first time. The training also improved the participants’ performance in two other important cognitive areas: working memory and sustained attention. And participants maintained their skills at the video games six months after the training had ended.
Evidence that the adult brain is capable of learning has been accumulating for more than a dozen years
A study of London taxi drivers, for example, found that their brains had changed as they learned to navigate the city’s notoriously complicated streets. Nevertheless, Gazzaley said the brain’s function often erodes steadily over time in many areas, with some exceptions, like wisdom. Given this, Gazzaley said it’s encouraging that even a small amount of brain training can reverse some of the age-related decline.
Gazzaley’s group found evidence of a possible brain mechanism that may explain the improvements he saw in his older subjects, and why these gains transferred to other cognitive areas. Electroencephalograph (EEG) recordings point to changes in a neural network involved in cognitive control, which is necessary to pursue goals.
The scientists measured midline frontal theta – or low frequency oscillations – in the prefrontal cortex, as well as the coherence in these waves between frontal and posterior regions of the brain. As the older “drivers” became more adept at the multitasking challenges of NeuroRacer, their brains modulated this key neural network and its activity began to resemble that of young adults.
Both of these measures –midline frontal theta and theta coherence – are well established neural markers of cognitive control that have been associated with many of the processes that enable people to pursue their goals
“We see this as evidence that the training may have improved our study participants’ ability to stay in an engaged, active state for a longer period of time,” says Joaquin A. Anguera, the paper’s first author and a post-doc in Gazzaley’s lab, according to the news release.
Indeed, the researchers found that the training-induced changes in this neural network predicted how well participants would do on a different test, called the Test of Variables of Attention (TOVA), which measures sustained attention. “The amount that midline frontal theta went up was related to something that was untrained, this other measure, the TOVA,” Anguera explains in the news release. “It implies there’s something that changed that was common to the training and to the task we tested afterwards.” See, "Brain Training Game Effective, UCSF Study Finds."
Gazzaley said these findings point toward a common neural basis of cognitive control that is enhanced by the challenging and high-interference conditions of the video game, and this might explain how racing a car in 3-D could improve something as seemingly unrelated as memory
If the finding holds, it could have wide application. Other brain disorders like ADHD, depression and dementia are also associated with deficits in cognitive control. “Follow up studies using functional Magnetic Resonance Imaging and transcranial electrical stimulation are still needed to better understand exactly how this network is involved in the performance changes,” Gazzaley says in the news release.
