为什么不把fibroblast直接reprogram成neural stem cells呢？neural stem cell 可
以扩增，而且有paper都显示transplant neural stem cells 有一定的改善疾病症状作
用。
还有一个我对iPSCs的疑问，现在好像比较成功的方法还是使用lentivirus来reprogram
(其他的方法有报道，但efficiency很低，没有被各实验室广泛使用)。既然
lentivirus 会随机插入基因组，这样会不会导致产生出来的iPSC cell line各不相同
？说不定有些可以变成neural stem cell, 有些或许分化效率极低或者就压根不能。如
果是这样，那么用这些iPS cell line去model disease 会不会得到一些误导的结论呢

的，short range, 有稳定平台的训练。后者是把身体当作一个整体，利用或制造不稳
定的训练。
决定力量的三要素是neural logical adaptation, muscle hypertrophy 和muscle
hyperplasia 决定。 muscle hyperplasia是肌细胞数量，是遗传决定的。neural
logical adaptation就是整个身体协同作用的能力，对functional strength 起决定性
的作用。muscle hypertrophy是肌肉的大小，是健美运动强调的。neural logical
adaptation的关键是把身体作为一个整体，各个动作要full range, 大小各肌群协同做
工，最好是训练时创造不平衡和不稳定。
力量基本和肌肉大小正相关，但肌肉大小也是有差别的。High tension, 小于等于
5reps练出来的肌纤维密度比较高。High reps, low tension 的肌肉肌浆比较多。

线性函数的意思是，满足叠加和数乘两条规定
1.
vector就是一个一维数组v
2.
dual vector的意思是，对v做加权平均时候的权值组成的数组w
one form的意思是这个加权平均函数
3.
(m,n)tensor的意思是，对m个one form，n个vector都是线性的一个map,
或者说是对m个one form，n个vector再做一次加权平均。最后得到一个数字。
这个另一次加权平均函数，就叫做tensor.
所以Tensor是一个对running index复杂点的东西的加权平均函数。
你不可能在这个函数里面看到权值的平方。

如果你知道一元函数的微积分。那么就可以推广到vector， tensor的

名教授更是厉害。他的铁牛也会在这样一种情况下，被嘎然终止，就是他严重的行为犯
规。之前，也有少数类似例子发生，教授由于某种原因遭大学校方处理，但铁牛还让延

不过，这次哥大的处理相当决然，关闭他的实验室，他的它处职位也立即发生倒牌效应
。我很想知道他的铁牛还保留吗？还是被扫地出门？
还有让人好奇的是：他的严重的行为违规。 十几年前，也有人因某种原因被解散实验
室，在学术界也怔了一下。可是庙小，过一段时间也没声音了。哥大庙大，影响则会更
大。
究竟是如何的行为违规？大家都很好奇。我认为最好公布一下，这对广大铁牛们和科研
人员们有个警戒，注意行为规范。

发帖数: 1622 | 48 i see your point, which is good!
if current modeling people think about the realistic neural firing property
into the neural network model, then it is good.
so now question is what kind of model these people used to generate
neuron-based firing pattern? leaky integrate-and-fire model? hodgkin-huxley?
or just statistically give a possion-like spiking pattern model?
pattern，不管这个pattern是poisson也好，非poisson也好，只要有人观测过、总结过
，就应该在neural network的单个神经元中体现出来。

当小鼠处于孤立条件下，海马状突起产生更多的神经干细胞，等待比较好的时期
[The Scientist: June 15, 2011 by Jessica P. Johnson] 哥伦比亚医学中心的
研究人员第一次提出证据表明海马状突起(hippocampus)中的神经干细胞的数量可
能不是固定的，能够被变化的环境条件所改变，其中海马状突起是大脑中负责记忆
、学习和情感的区域。通过比较小鼠暴露在刺激的环境下和在孤立、压力的环境下
的海马状突起的变化情况，他们发现那些处在孤立条件下的小鼠海马状突起产生的
神经干细胞数量要比处于刺激中的小鼠多，其中这些神经干细胞分化后只能产生神
经元。
研究人员提出假设，即在压力或穷乏情况下，大脑通过堆积神经干细胞让自己做好
准备，这样它就能适应刺激性较大的环境条件下的要求，因为人们已知刺激的环境
能促进更多神经元的产生。这些研究结果，2011年6月9日在线发表在Neuron杂志上
，展示了一种新形式的神经可塑性(neural pla... 阅读全帖 |
