Benzodiazepines, such as valium, are used both in clinics and for
recreational purposes, but lead to addiction in some individuals. Addictive
drugs increase the levels of dopamine and trigger synaptic adaptations in
the mesolimbic reward system, but the neural basis for the addictive nature
of benzodiazepines remains elusive. Here, they are shown to increase firing
of dopamine neurons in the ventral tegmental area through GABAA recept |

发帖数: 3446 | 31 我说的是“基本”是数字的。神经元最基本的工作方式，就是产生动作电位，并把它传
到下面一个神经元。动作电位本身是没有大小概念的，其实就是数字的，0和1。
动作电位本身是研究得非常清楚的。但这些神经数字脉冲(spikes)是如何编码的，现在
还没研究清楚。我以前上过一门Neural Computation的研究生课，成天就是看各种对此
的假设和研究文章，一大堆公式，各种synchrony啥的，作业全是数学证明和计算，所

一个神经元接受很多其他神经元的输入，通过还不太清楚的很复杂的过程，决定是否产
生动作电位。这个复杂的过程，一般在工业界模拟起来，就简化为一个积分器的机制。
这其实就是IBM现在出品的那种神经芯片的工作原理，其好处是能耗很小，实现某一些
ML算法很容易。坏处是编程方式不是von neumann的，更像用模拟电路来编程。 |

我抽屉里有一本2000年买的本科生教材。计算理论基础。harry R Lewis写的。5。2节
第一段：
"
In other words, we shall be thinking of the formalism of Turing machines as
a programming language,
in which we can write programs. Programs written in this language can then
be interpreted by a
universal Turing machine----that is to say, another program in the same
language.
"
二是这个trick在什么地方？
Self Interpret的技术在Kenneth Thompson的图灵奖lecture有一段描述。

发帖数: 2583 | 42 of course, you can call any functional and anatomical neural unit as a "
circuit", there's no strict definition of this term. And no need to care
that.
Actually, even as the example you give, it's not as linear as you think,
when 运动神经元形成一个躲避动作, it's actually a series of feedback signal
sent back to 神经中枢处理器, so there are a lot of "loops" here.
