mjburgess: It was my understanding that all this connectome-based research was largely a deadend, because it doesnt capture dynamics, nor a vast array of interactions. if you've ever seen neurones being grown (go search YT), you'll see it's a massive gelatinous structure which is highly plastic and highly dynamic. Even in the simplest brains (eg., of elgans), you get 10^x exponential growth in number of neurones and their connections as it grows.
mjburgess: 据我所知,所有这些基于连接组的研究在很大程度上都是一个死胡同,因为它既没有捕捉到动态,也没有捕捉到大量的相互作用。如果你;我见过神经元生长(去搜索YT),你;我会看到的;这是一个巨大的凝胶状结构,具有高塑性和高动态性。即使在最简单的大脑中(例如,埃尔根人的大脑),随着神经元数量的增长,神经元数量及其连接也会呈指数级增长。
PaulKeeble: Going to need a significant improvement in the software to get it to map a human. The fruit flu has 140,000 neurons and 54.5 million synapses and the AI that mapped it required a post process with humans checking it all with 3 million edits and they still have to identify every neuron type.<p>A human brain has about 86 billion neurons and quite likely many trillions of synapses and that is likely an underestimate. That 3 million edits will turn into 3 million * 10^6 at least manual edits, that doesn't seem feasible. The error rate on the fruit flu would have to come down into the single digits to be usable to map a human brain. So an improvement from about 6% of synapses to 0.000006%. That is one heck of a jump in improvement for an AI.
PaulKeeble: 需要对软件进行重大改进,使其能够绘制人类地图。水果流感有14万个神经元和5450万个突触,绘制它的人工智能需要一个后处理过程,人类需要对其进行300万次编辑检查,他们仍然需要识别每种神经元类型<p> 人脑大约有860亿个神经元,很可能有数万亿个突触,这可能是低估了。300万次编辑将变成300万次*10^6,至少是手动编辑,这不会;这似乎不可行。水果流感的错误率必须降到个位数,才能用于绘制人脑图谱。因此,突触的比例从约6%提高到0.00006%。这对人工智能来说是一个巨大的进步。
