Usually the word has some negative connotations. But at some times, it can be equivalent to "老实人". Because "老实人" will do things very straight, like "缺根筋"。

In terms of the original negative connotation, we find that the "经" in "发神经" sounds close to the "筋" in "缺根筋", which leads to an association between the two short sentences, in other words, there are similarities in the meanings between them, so in a certain context, "发神经" can be equated with "缺根筋". But it must be pointed out that the emotional overtones of "发神经" are more serious, because it is too direct.

In traditional Chinese culture, i.e. in traditional Chinese medicine, "筋脉" are an important concept, and sometimes we can understand them as a collection of neurons, but we can never directly equate the two. "筋" is a real thing, and there is no direct evidence of its existence in "脉" at present. "筋" correspond to the control of a muscle in the human body, associated with other muscles or fascia, etc. Therefore, the "缺根筋" can be regarded as a person who loses control of the "muscle" of the brain at the level of consciousness. We can have several different descriptions of this: first, it is considered to be a condition, i.e., "脑子有病", second, it is believed that it is because something has hit the person's head, and the person's head is showing swelling, i.e., "脑子有包" or "脑子有泡", and third, it is believed that the "筋" in it have been removed, that is, "脑子抽筋"。

The above does not necessarily refer to madness, if you want to refer to madness, there is an allusion, which is "范进中举", which comes from the Chinese literary novel "儒林外史". Moreover, the rational use of this allusion can achieve some good effects, such as “中举的范进们，不是哪个个人，不是哪个群体，而是那些发展着的而又衰落着的封建王朝。它们那少数人的盛世，疯狂了伟丽宫城之外的穷苦的农民们。” The satire of the feudal system in the allusion is used here, or “那仿若范进模样的人狂笑在路上”, and here the crazy image of Fan Jin when he is just lifted in the allusion can be regarded as a metaphor.

Since I am not a native English speaker and I am not very good at learning English (;D) Therefore, the machine translation used in the English part of the above content may be biased.还请见谅。

通常来讲，该短语多少带有些许的负面色彩。但是在一些语境下，它可以被等价为”老实人“。因为”老实人“总是做事情很直，就像是”缺根筋“。

就原本的负面意来看，我们发现”发神经“中的”经“音近”缺根筋“中的”筋“，这导致了这两个短句之间存在一定的联想关系，换而言之，这两者之间含义相近，所以在一定的语境下，”发神经“可以等价为”缺根筋“。但必须指出的是，”发神经“的含义的情绪色彩更为严重，因为它太直接了。
