      Researchers have shown, for the first time ever, that memories are stored in specific brain cells. By triggering a small cluster of neurons, the researchers were able to force the subject to recall a specific memory. By removing these neurons, the subject would lose that memory.

      I’m not sure if you mean in our brains or in a computer, but I’m going to answer about the computer anyway 😉

      Memory is usually stored on a computer as tiny little squares which are either ‘on’ or ‘off’. All information is stored in terms of series of ‘on’s or ‘off’s

      Brains are very hard to understand. How can our brains cope with so much information bombarding us our entire lives?! As our computers have become faster and cleverer over the years, we’ve had to drastically increase the size of their memories to cope (bigger hard drives etc), but our brains chug along happily, never appearing to get ‘full’! What exactly a brain memory IS is hard to say, but computer memory is much easier to understand. Computers just think in binary numbers, so if you can write down enough ones and zeroes (on/off, up/down… whatever) on a big long piece of paper (which really is essentially what a hard drive does!) your computer can remember anything 🙂
