The trajectory of the network's activity cannot be easily explained by the simple local circuits described earlier.

网络活动的轨迹无法通过前面描述的简单本地电路轻松解释。

But even this allowed simple circuits, like the logic gates from Episode 3, to be packaged up into a single component.

但即便如此，也可以将简单的电路（例如第 3 集中的逻辑门）封装到一个组件中。

In the early days, an IC might only contain a simple circuit with just a few transistors, like this early Westinghouse example.

在早期，一个 IC 可能只包含一个简单的电路，只有几个晶体管，就像这个早期的西屋示例。

So it's not really that surprising that the simple neural circuits driving these motions are basically little rhythm machines, with electrical patterns that give rise to coordinated motion.

因此，驱动这些运动的简单神经回路基本上就是小型节奏机，其电子模式可产生协调的运动，这并不令人惊讶。

So today we’re going to take those Boolean logic gates we learned about last week to build a simple ALU circuit with much of the same functionality as the 74181.

因此，今天我们将采用上周学习的那些布尔逻辑门来构建一个简单的 ALU 电路，其功能与 74181 的大部分功能相同。
