Memories Are Made of This

New memory study records the activation（n.激活） of human brain cells deep inside the living brain.

The mystery of what happens in our brains when we remember something is fascinating not only from a scientific perspective but also because the experience of recall can be so, well, memorable. Thinking backwards we become sensory（adj.感官的）time travelers; recalling sights, sounds, events, emotions - all in the blink of an eye. But what happens in our brains when we travel backwards?

For years scientists have told a story that goes roughly like this: when we experience something - say riding a bicycle for the first time - a network of neurons in the brain are activated. Then, later on, when we recall that first experience, that same network, or something like it, is activated again.

There is some roundabout（adj.迂回的，间接的） evidence that this is exactly what is going on, but nothing direct. That is, until now. A US and Israeli research group have provided the strongest evidence so far that this story is accurate by recording individual neurons inside the living human brain.  One of the authors of the study, Dr. Itzhak Fried, describes it like this: "In a way then, reliving past experience in our memory is the resurrection（n.复苏）of neuronal activity from the past".

      新的记忆研究记录了在大脑深处的脑细胞的活动。
      当我们记忆时，我们大脑中所发生的事是如此奇妙，不仅仅因为科学的观点，也因为回忆的过程确实是如此的让人难以忘怀。当我们回忆时，我们变成了有感觉的时间的旅行者，回忆起画面，声音，事情，情感都在一眨眼之间。但我们在回忆时我们的大脑究竟发生了什么？
      多年以来，科学家讲过一个大约是这样的故事。当我们经历一些事情时，比如说第一次骑自行车，这时大脑某处的神经元网络就活动起来。然后，当我们事后去回忆时，相同的神经元网络或者一些类似于神经元网络的东西又活动起来了。
      有一些间接的证据证明在记忆时大脑中确实有事发生。那就是，一个美国和以色列的研究小组通过记录活动着的人脑中的独立神经元的活动，从而提供了目前为止对那个故事最有力的证据。这项研究的一个作者Dr. Itzhak Fried如此形容到“回忆的过程是神经元活动复苏的过程。”
