Scientists find where the brain stores memories

Scientists may have developed a method for reading memories but there’s one problem — they have to slice the brain into thin slices to do it.

A group of rats were trained to perform a task using one of two methods. Afterwards, researchers found they could identify which rat had done it in which way, simply by performing an autopsy on the rats’ brains.

In the experiment, reported in the journal Nature, the rats were given three slots to put their nose into. First they learnt to investigate the middle slot, where they heard either a high-pitched or low-pitched sound.

For half the rats, the low-pitched sound meant that the box on the right contained water, for the other half it was the one
