Researchers at UC Irvine have found that how much detail one remembers of an event depends on whether a certain portion of the brain is activated to “package” the memory.

In experiments using functional magnetic resonance imaging (fMRI), the scientists were able to view what happened in the brains of subjects when they experienced an event made up of multiple contextual details. They found that participants who later remembered all aspects of the experience, including the details, used a particular part of the brain that bound the different details together as a package at the time the event occurred. When this brain region wasn’t activated to bind together the details, only some aspects of an event were recalled. The findings appear in the current issue of Neuron.

“This study provides a neurological basis for what psychologists have been telling us for years,” said Michael Rugg, director of UCI’s Center for the Neurobiology of Learning and Memory and senior author of the paper. “You can’t get out of memory what you didn’t put into it. It is not possible to remember things later if you didn’t pay attention to them in the first place.”

The scientists presented 23 research subjects with a list of words while they underwent an fMRI scan. The words were in different colors and would appear in one of four quadrants on a screen. The subjects had to decide whether the words represented an animate or inanimate object. Later, the participants were presented the words again, interspersed with words they had not seen before, and asked if they remembered seeing those words before. They were also asked if they remembered in what color the word had originally been and in which of the four quadrants it had originally appeared.

If the participant could later remember the color of the word, a particular area of the brain associated with color processing was especially active during learning. If the subject later remembered the location of the word, activity was seen in an area associated with spatial processing. But if the subject remembered the word, the color and the location, then another critical brain region became involved. The researchers observed enhanced activity in the intra-parietal sulcus, a part of the parietal cortex. It appears that this region is responsible for binding together all the features of a particular memory so that contextual details, as well as more central aspects of the event such as the identity of the word, can later be recalled.

“We know that if the intra-parietal sulcus is damaged, then someone cannot attend to multiple aspects of the same object, such as its size and color,” said Melina Uncapher, a graduate student researcher and lead author of the study. “This study provides empirical evidence for how critical this region is for bringing the constituents of a memory together in the brain.

“Memory is more than a sum of its parts. A complete memory of an event requires that the features of the event be brought together and processed by the brain as a common perceptual representation, before being stored.”

Leun Otten of University College London collaborated on the study. The research was funded by the National Institute of Mental Health and the Wellcome Trust.

继 续说Voice or Noise，昨天又拿出来翻了几页，读到几句重要的话，原来一直都从眼皮底下滑过去了。现在很想在网上把那两本买下来，看到封面上敲着两个18禁的红章很 是碍眼，简直是偏见+误导，比起某些堂而皇之出售的黄色少女漫画，这两本就一个kiss镜头还被。。。 >< T^T !!!

首 先Voice or Noise是一个过程，也是外在的比喻，和Schrodinger's Cat是两条完全一致且平行的导线。实质的内容是说一旦深究某种蠢蠢欲动的想法后，那个人就要有勇气和觉悟去承担无法改变的事实。故事有两个，一个是说名 叫Acht的猫从来不提以前饲主的事情，它是被抛弃的，年近90的老爷爷搬家后就顺手把猫留给了新迁的承泽，对于他来说，Acht无足轻重。可Acht只 是逃避事实罢了。那场车祸后，Acht不会说话了，因为它的灵魂去了平行宇宙，那儿有老爷爷等着它。你并没有抛弃我不是么？答案是否只是一种可能性，在盖 子被揭开之前，是或否占有同等的比重，猫既死又生，或死或生。振一郎在梦里听Acht一再提及老爷爷和他的世界，开始烦躁。Acht，你的世界在这里，那 人早就抛弃你了，快点回来。事实也许只有一个，在被旁观者澄清之前当事人并不是不知道，而是因为害怕承担失望而把自己囚禁在薛定谔的暗箱，小心呵护起一个 心结。振一朗冲动说出的话杀死了一只孤单的猫。猫的故事也只是环中环，因为振一朗也不得不面对自己的暗箱。驻足于模棱两可的国界，跨出决定性的一步就有了 答案了。

You can only leave it completely behind you, after it's infiltrated you. So even if it's a sugar coated trap, jump in, get hurt. That might be the only way to truly free yourself.

传说大约在公元前400年，古希腊的雅典流行疫病，为了消除灾难，人们向太阳神阿波罗求助，阿波罗提出要求，说必须将他神殿前的立方体祭坛的体积扩大1 倍，否则疫病会继续流行。人们百思不得其解，不得不求教于当时最伟大的学者柏拉图，柏拉图也感到无能为力。这就是古希腊三大几何问题之一的倍立方体问题。 用数学语言表达就是：已知一个立方体，求作一个立方体，使它的体积是已知立方体的两倍。另外两个著名问题是三等分任意角和化圆为方问题。 古希腊三大几何问题既引人入胜，又十分困难。问题的妙处在于它们从形式上看非常简单，而实际上却有着深刻的内涵。它们都要求作图只能使用圆规和无刻度的直 尺，而且只能有限次地使用直尺和圆规。但直尺和圆规所能作的基本图形只有：过两点画一条直线、作圆、作两条直线的交点、作两圆的交点、作一条直线与一个圆 的交点。某个图形是可作的就是指从若干点出发，可以通过有限个上述基本图形复合得到。这一过程中隐含了近代代数学的思想。经过2000多年的艰苦探索，数 学家们终于弄清楚了这3个古典难题是“不可能用尺规完成的作图题”。认识到有些事情确实是不可能的，这是数学思想的一大飞跃。然而，一旦改变了作图的条 件，问题则就会变成另外的样子。比如直尺上如果有了刻度，则倍立方体和三等分任意角就都是可作的了。数学家们在这些问题上又演绎出很多故事。直到最近，中 国数学家和一位有志气的中学生，先后解决了美国著名几何学家佩多提出的关于“生锈圆规”(即半径固定的圆规)的两个作图问题，为尺规作图添了精彩的一笔.

Tacky Souvenir
序| 夏

太阳照的人眼睛发直，再过不久知了该发情了，房前的霞草该纵横疯长了。今天来了个可爱的女孩子，留着一头亚麻色的卷发，极为优雅的梳成一柳马尾，一进门就冲勉强从床上爬起的我咧嘴笑。

我的眼皮像千斤重的铁锅死扣着，自认为努力撑大眼睛假装清醒了，最后也只是眉毛无端的向上挑，眼睛依旧是一眯细缝。她看到我这副模样，噗嗤一声笑出来，然后很抱歉的说，一大早来看房子真是不好意思。

我说没关系，天气那么热，再睡下去会在被窝里融化。我从冰箱里挖出两升的大瓶苏打水，刚想凑着嘴狂饮，突然意识到有人看着，一下子打住了。你要不要也喝一点？这句话最终没问出口，考虑到瓶内八成全是我的唾沫。我僵直的抓住瓶子看她，她愣了会儿，意会过来后笑着说不渴。我找到个许久不用的小杯子，给自己正儿八经的倒上满满一杯。

“你的房间是这间。”一杯下肚，精神抖擞了，我推开房门开始做小本生意。

房间很朴素，除了床，书桌和衣橱并无多少可以奢侈的空间。地板是木质的，四周还贴了墙纸，就一个月300的房租来说已经相当体面，最重要的是，推开窗便能享受凉爽的穿堂风，还能看到不远处的小河。三年前，我就是看重这不可多得的窗景才住下来的，哪想到脑门顶着一滩水。昨天在确认有人要来看房后，我花了整个下午把天花板上的裂缝用水泥封了一层又一层，最后草草涂上白墙粉遮盖豆腐渣工程。我不免有些神经质的偷瞄了一眼那块禁地，又用余光打量马尾辫的反应。担心似乎是多余的，她一脸满足的探头看窗外，丝毫没有察觉本质的硬件问题。她在窗前停留很久，我有些不耐烦的靠在桌沿上等着。看着那一头卷发的后脑勺，左顾右盼的好奇表情，忽然有种时间错位的不真实感。我使劲揉眼睛。

房子谈的很顺利。她又问了水电网络等的闲杂问题，当下就敲定要搬了。走过客厅的时候，她望见壁柜上放置的照片，走近仔细瞧了瞧。

“你的家人？”她问。

“不是，全都是这里房客的照片，很多是我朋友。”

“哦。。。”这个哦拖着长长的尾音，她的眼睛走马观花似的从左扫到右，最后在一张三人合照上停留了下来。

“他也住这里吗？”马尾辫指着照片左侧的男生问。

“不，他去年搬走了。” 我不动声色的回答。

马尾辫好生失望。

你别那么纯情了，也不想想那个天花板。

寒暄了几句过后，她说要赶课先走了。

我送她到门口，顺口提到，“其实我也只是代理这栋房子的，房东暂时不会回来。”

她没再多问，这样也好。

我关上门，漫无目的的来回走，然后插着腰定在原地站着不动。我回想了很多事，最后放声大笑。

林水，三年前你把那烂摊子甩给我，现在我微毫不差的转让给另一个人，和我有着同样卷发的新房客。没想到如此笨拙的技俩还能重复使用。

我再次走进一周前还属于我的房间，抬头看微微隆起一块的天花板。

也许该拆开彻底补修一下了。

自Jady8点半在Gtalk上出现之后，就没干过一件正事。看了新闻，看了Wikipedia上关于毕加索的生平。他的原名有十多个字那么长，虽然被很多人指责是贪生怕死的战争中的胆小鬼，人家不还是徒了个和平奖。下了十多个podcasts，开始一个个的听。搜中文的podcast，只有寥寥几个结果，剩下的都是“女人的秘密”之类低俗节目。忽然想吃西瓜，想到西瓜很开心，又想点蚊香过夏天。就这样过了一晚上。躺下nap半小时想到可以用于小说的零碎片断。曼榛可以是个容易放弃的人，林水也是，虽然原因不同。她去过很多地方，但都待不长久，在对那个城市彻底失望之前离开，以便过后回味时还能保留美好的回忆。所谓的得不到的都是好的，而事实是，放弃太早只会两手空空而归。而林水却驻足不前，守着同一个地方不愿意离开，因为没有信心再去追寻。在原地打转转只会更加眩晕。对现状的放弃被美言为对未来的憧憬，而对未来的放弃却被偏袒为对现状的不懈。就是这样一番懦弱，无影的伤疤一旦揭开便会掀起一场战争。

竟然1点了，吐啊。
