How to Super-Size Your Memory

You can super size your memory to make it more like that of a world champion, according to scientists.

You can super size your memory to make it more like that of a world champion, according to scientists.  Neuroscientists Boris Nikolai Konrad had his own brain scanned for the research.

Scans reveal that while memory champions' brains are nothing special in terms of anatomy, they do show changes in brain connectivity.

What's more, neuroscientists were able to train people with ordinary memory skills to emulate the masters.
The learners could remember lists of names at a time and showed similar brain connectivity patterns.

Lead researcher, Dr Martin Dresler, of Radboud University Medical Centre in Nijmegen, The Netherlands said, "A good memory is something you could learn and you could train for," said
"And if you use these strategic mnemonic training memory strategies you can really considerably increase your memory, even if you have a very bad memory at the start."
The findings , based on brain scans of 23 world memory champions, are published in the scientific journal, Neuron.

They are based on mnemonics, memory devices that help you recall lots of information, especially in the form of lists.
Techniques include loci, or memory palace, an ancient method where you make an imaginary journey through a place you know well, such as a building, using each location as a visual prompt to store information.

Memory techniques include imagining yourself walking through a palace
Neuroscientists studied the brains of memory champions, who excel at memorising vast quantities of information, from playing cards to names and faces. They scanned their brains using functional magnetic resonance imaging (fMRI), which measures brain activity by detecting blood flow changes. They then compared their brains with those of people of a similar age who had similar IQs.



The researchers found subtle differences in connectivity patterns across a large number of brain regions. However, no single region stood out.
"There we learned that neurobiological differences between these world class memory champions and more or less normal control subjects appear to be quite widespread, distributed and subtle," Dr Dresler explained.

It's not clear however that while the mnemonic techniques are useful for remembering long lists of information, they help improve everyday memory.

The scientists then trained people with typical memory skills to see if they could improve. Some were given training in techniques used by memory athletes, others had memory training that did not include mnemonic strategies, while the rest had no training at all. After six weeks of training for 30 minutes a day, the subjects all had another brain scan.

The researchers saw a big increase in memory powers for those given training used by memory athletes. They went from recalling an average of 26 to 30 words from a list of 72 to remembering more than 60. This group also showed changes in brain connectivity.
"In a sense they really develop brain patterns that remind us of those of memory athletes," said Dr Dresler. "This specific pattern in brain connectivity appears to be the neurobiological basis of these increased and superior memory performances."

Dr Boris Nikolai Konrad who himself is a neuroscientist had his own brain scanned for the research and trained the novices. He holds two world records for memorising hundreds of words, and names and faces, in a short time and is also listed in the Guinness Book of World Records. Despite this, he says he wasn't born with exceptional memory skills.
"In school, I nearly failed because I couldn't remember English vocabulary," he told BBC News. "It took me a while to realise that there's something that helps me in memorising, particularly these memory techniques.

"I really love sharing this idea that you can improve your memory because I still don't know why we don't teach this to kids, to people, much more, because in my opinion it is really useful."
