The money should be divided up into small seeding funds and promote start-up
companies to run. It should be used as the competition award for the best
team who come up with the fastest algorithm, the most innovative imaging
tools, and the new chemicals designed to trace the connections. Small scale
competitions should be held to find the teams and then the work distributed
to several best teams who will deploy the new data into a centralized
database. A small biology team will conduct the functional test but needs
to be large scale.
The principle here is, decoding a whole brain is not like linearly added up
by small pieces, smash a supercomputer into small pieces and study each of
them won't tell you anything about the whole computation principle of it.

I do not agree that it is an engineering project rather than a basic
research. The only thing worth competing by companies is the computational
tools need for data analysis, which will not happen in early days of
methodology development.
Talking about next generation sequencing, the concept is really simple,
massive parallel sequencing. Once the concept is funded, small ideas, like
different chemistry, will compete each other for the simplest strategy. Once
the chemistry is determined, engineering will take place to improve the
throughput.
Not much biology here in sequencing development. But still science first,
engineering second.
We should wait for the true scientific breakthrough first, which is more
likely to happen in small labs, not in few big groups.

骂声一片啊。我就唱个反调吧。
I think the discussion has mixed three different things:
(1) The existing connectome project
(2) The big pie-in-the-sky activity map
(3) The current technology development program
And my points:
(1) Measuring activity is important. The limited use of the worm's wiring
diagram says precisely the importance of knowing activity.
(2) Measuring activity in worm is not a done deal. Actually, if any
technology development can lead to measurement of activity at sub-cellular
resolution and global scale, that'll be awesome.
(3) For the current program, the goals are set as technology development
and the activity map is left as an unspecified long-term inspiration. To me
it says that the plan is not totally out of control. It's a calculated
gamble to take a risk.
(4) $100M isn't a whole lot of money in the big picture. It roughly
supports 100 labs, each with 4 or 5 people. The annual budget for NINDS and
NIMH combined is about $3B. Even NIAAA has a budget of about $500M a year.
(5) According to the NYT report, Cori Bargmann is charged to lead a team to
define the scope and plan of the project. She's a fan of neither big
science nor the connectome. So I think we can still be hopeful.
(6) Waste is unavoidable in organized human activity at this scale, period.
So to me the criticism on inefficiency is kinda 求全责备.
I think the discussion has mixed three different things:
(1) The existing connectome project
(2) The big pie-in-the-sky activity map
(3) The current technology development program
And my points:
(1) Measuring activity is important. The limited use of the worm's wiring
diagram says precisely the importance of knowing activity.
(2) Measuring activity in worm is not a done deal. Actually, if any
technology development can lead to measurement of activity at sub-cellular
resolution and global scale, that'll be awesome.
(3) For the current program, the goals are set as technology development
and the activity map is left as an unspecified long-term inspiration. To me
it says that the plan is not totally out of control. It's a calculated
gamble to take a risk.
(4) $100M isn't a whole lot of money in the big picture. It roughly
supports 100 labs, each with 4 or 5 people. The annual budget for NINDS and
NIMH combined is about $3B. Even NIAAA has a budget of about $500M a year.
(5) According to the NYT report, Cori Bargmann is charged to lead a team to
define the scope and plan of the project. She's a fan of neither big
science nor the connectome. So I think we can still be hopeful.
(6) Waste is unavoidable in organized human activity at this scale, period.
So to me the criticism on inefficiency is kinda 求全责备.

首先,我对你的头两点举双手赞成。如果我有自己的lab,我也会花一些精力去develop
technology, establish platform,虽然这些不属于一般R01会支持的方向。但是磨刀不
误砍柴工。
你剩下的基调也许是:
1, 反正已经要有人要拿一笔大钱了,我们应该希望好的事情发生,而不是总往坏处想
2,反正也要浪费,这样浪费未必就是最坏的
我觉得你有点wishful thinking
我觉得作为一个实验室的PI,这样想问题没什么大问题。做实验总是失败的多,花了一
笔大钱,做了一个实验,总希望它work。拿到一笔grant,不花掉就得交还政府,随便做
点什么实验,买个仪器,总会有用的。
不过,作为整个scientific community ,这样想就会有大问题了。做science,最大的
inspiration 不来自于金钱,而来自于好奇心。近三十年了,砸50个M以上的大钱,从
来就没砸出什么新鲜玩艺儿来。
你拿NINDS 和NIMH的budget来证明100M不多,有点不靠谱。除了NIGMS,NIH的每个
institute大概都只有一个program专门支持偏基础的研究,每年能fund的新R01不过20几
个。100M, 包括F&A, 那是200个左右R01的水平。
最后,寄希望个别人物的英明决策,就更不靠谱了。其实经费不景气的时候,如果公平
竞争,大实验室会变小,小实验室倒一片,然后最具创新力的小实验室会立足脚跟。都
经济好转,这些有创新力的小实验室就会变大。
而且,真要做brain,新的突破点可能不来自于现有的生物学,甚至不来自于已有的交
叉学科。这样瞎投钱,对科学本身而言,就是揠苗助长。

对的 实际上connectome不说,BAM和这次的BRAIN是容易混淆。不过话说回来,BRAIN是
从BAM的倡议来的,BRAIN的钱最终肯定会有大批落到BAM的人手里。
你的观点我有赞成也有不赞成的,具体说说:
1> neuronal activity当然是重要的。但是上BAM的话,问题有几个:技术不ready,而
且甚至我们都不知道怎么设计和发展需要的技术,很有可能为了实现全脑BAM需要全新
路线的技术;目标不清楚,记录了BAM然后呢?这个意义上其实connectome也是同样问
题:有了connectome,有了BAM,然后呢?大脑的问题就解决了么?当年HGP也是这么说
的,结果HGP的数据虽然很有用,但是从初始目标上其实是失败了的。后来的ENCODE/
BAM我感觉都有借HGP的经验忽悠的意思,我倒是很担心他们的结果不光从初始目标看是
失败的,就是从积累groundtruch上也是失败的,毕竟像基因组序列那样稳定不受环境
和组织特异性影响的东西不多见。
2> BRAIN initiative说技术发展多了,说BAM少了,这个确实是好事。至少BRAIN
initiative的人没有那么大忽悠了,呵呵。不过我很好奇他们所谓的技术发展是有明确
路线的,还是就是圈钱发给圈里人的。如果是前者那至少从公开信息上我没看到,如果
是后者那就不值得鼓励了,原创技术很有可能是不知名的小lab发展的,而现在已经很
成功的大lab其实并不那么缺钱。
3> 1亿确实不多。但是也是好几百个R01的数目,换句话说要是奥巴马政府不是单独拨
款而是需要DAPRA/NIH从预算里分出钱来,那就意味着上百个lab要关门了。
4> Cori当头算是唯一的亮点吧。Cori似乎不像是喜欢大工程类型science,或者fancy概
念的科学家。但是怎么说呢,你可能也知道国内曾经搞得蛋白质工程;又叫凤凰工程啥
的。本来是饶子和贺福初忽悠的,当时饶施在国外是拼命反对。等他们回去了其实有点
加入这个工程的意思,他们的逻辑我也理解:这钱与其让蠢货分了浪费了,不如我们借
这个名目拿来做好的science。亡羊补牢也算是个好事吧,但是是不是干脆没有这些大

其实现在的grant application, 和写八股文差不多。各种条条框框,按照那个红宝书
把框架写好,然后再往里面填关键词就差不多了。
至于说那个往疾病上扯,主要是不扯的话无法向政客交代。我们上那个grant workshop
红宝书的课的时候就明确的被告知,绝对不能说因为什么东西还没有人做所以我们就应
该去做,应该说那个东西对疾病多么多么的重要,所以我们要去做。
但是要硬扯疾病是一个很痛苦的事情啊,又不能硬着头皮瞎扯,怎么都得弄个支持证据
是吧。这个就是为什么大家一边一个个义愤填踊的痛骂GWAS不可靠,一边大幅度的去引
用那些GWAS的文章来证明自己做的东西和疾病多么多么的有相关的原因。所以Nature
Genetics的引用因子一路高升,不是偶然的。
