For the first time, scientists have managed to identify what they believe to be the building blocks of memories - specifically, the neurons that handle the information related to where we are and where we've travelled in the past. By lighting up these building blocks in the brains of mice, it's hoped that we can learn more about the way memories form in our own brains, the researchers behind the experiment say.
