For decades, researchers thought that little could be done once the brain started to decline. Neuroscientist Michael Merzenich of the University of California at San Francisco found out however, the brain remains plastic throughout life. With training, he added, it can be rewired to learn new skills.

Keeping this in mind, the elders are now re-discovering childhood with the aid of computer game company Nintendo. The Ninty DS offers Dr. Ryuta Kawashima's Brain Age and the same is also expected to come for the Wii. This title, which was developed with the help of respected Japanese doctor Dr. Ryuta Kawashima, advertises that it can train your brain in just a few minutes a day. Merzenich on the other hand, came up with a computer-based set of exercises that a user must work on with an hour a day for eight weeks.

As we speak, there is still no concrete evidence if these people can actually delay, much more stop cognitive decay.  People must be thinking there is definitely no harm in trying because 15 months after, Brain Age is still highly popular especially in Japan. To date, 4 million copies of this title have already been sold worldwide.

You frantically search for those darn glasses of yours only to realize that they are only placed in your shirt. You happen to bump into an acquaintance and you were so embarrassed because you can't even remember his name. You were writing an amount in your cheque book and you suddenly get confused, is 40 spelled as 'forty' or 'fourty'...Sound familiar? Well, maybe you can use a little help from Dr. Kawashima's Brain Training: How Old Is Your Brain? which will be launched in the United Kingdom tomorrow.

The game was already a phenomenal success in Japan and it already sold 2.4 million copies. The game allegedly stimulates your brain and helps train mental awareness and your long-term memory by being used for a few minutes each day...that is according to its creators.

Dr. Ryuta Kawashima is a respected neuroscientist and he developed a series of quick but challenging exercises designed to energize the brain. The game will go on sale tomorrow (Friday, June 9) on U.K. and it would have an estimated retail price of around £20 Pounds (or roughly $37 U.S. bucks).
