A brief summary abount How to see a memory on Nautre.

In the talk of Letters from Google WuJun said that even though we could cure all kinds of cancers, this could only lengthen 3.5 years of human life on average. In fact, the demon of human is ageing, which means people get sick such as amnesia, cancer when getting older. Many top researchers devote their lives to this nobly course, i.e. to alleviate human suffering and promote human health. Hopefully, one day we can cure cancer with the help of Bigdata.

This article How to see a memory mainly tells us:

In microscope, cells with more CREB(a key memory protein) are more electrically excitable when mice learn and recall.

In a broder sense, a technique call multi-voxel pattern anylysis(MVPA), sometimes called memory decoding uses computer algorithm feeded with fMRI(functional magnectic resonance imaging) data to analyse neural pattern when human learn and retrive memory. Researchers show that different people share the same memory fingerprint when they recall same scene.

In this article, powerful technological innovations in human and animal neuroscience enable researchers to uncover the physical trace of a single memory. Advance in this field may help to reveal why memories fail when we are old or get disease.

有用的积累：

• Only in the past decade have new techniques for labelling, activating and silencing specific neurons in animals allowed researchers to pinpoint which neurons make up a single memory (see ‘Manipulating memory’).
