在NEURON .MOD文件中，各节的操作顺序是什么? [英] In NEURON .MOD files what is the order of operations of the sections?

问题描述

以哪种顺序执行NEURON .MOD/NMODL文件节中的命令?具体来说，在以下几个块中:DERIVATIVE，BREAKPOINT和NET_RECEIVE.

In what order do the commands in NEURON .MOD/NMODL file sections get executed? Specifically, within these blocks: DERIVATIVE, BREAKPOINT and NET_RECEIVE.

推荐答案

对于每个时间步，执行顺序如下:

For every time-step, the order of execution is as follows:

1. NET_RECEIVE :如果存在net_send()事件，该事件针对该机制，则首先执行此处的行.否则跳过.
2. BREAKPOINT 中的行:SOLVE ... METHOD行被忽略.执行SOLVE之后的所有行.使用printf()语句，您将看到两个调用.但是，其中一个调用实际上并未设置任何状态变量.用于计算导数.
3. 最后， DERIVATIVE 块:计算导数(X' = ...)的值.请记住，要获取状态变量实际更改的值，请乘以dt.

1. NET_RECEIVE: If there is net_send() an event that targets this mechanism, lines here are executed first. Skipped otherwise.
2. Lines in BREAKPOINT: The SOLVE ... METHOD line is ignored. All lines after SOLVE are executed. With a printf() statement, you would see two calls. However, one of the calls does not actually set any state variables. It is used to compute the derivatives.
3. Finally, the DERIVATIVE block: The values for the derivatives (X' = ...) are computed. Keep in mind, to get the value by which the state variable actually changes, multiply by dt.
