Every time a reader questions the content of the article, the author will carefully write a single chapter to answer it.

When a brother saw a sentence in the first chapter of this article, "Currents on synapses," he was skeptical.

And think that the author is lacking common sense - "The synapses transmit neurotransmitters, you don't even know this, and you still say that you can read the paper?" ”

Well...... Like this brother, after reading a sentence in the first chapter, I think that the author lacks common sense, and the author is the first time to encounter it.

To be honest, the author didn't think that anyone would find fault here when he wrote that sentence, because this sentence was passed by in the text, and the meaning was actually very vague - "electric currents on synapses", which actually refers to changes in electrical potentials on nerves and synapses.

Chemical transmitters are transmitted between synapses, this is the content of high school biology, to be honest, the author Jun thinks that everyone who has graduated from high school knows this, if a person knows the word "synapse", then he must also know that neurotransmitters are transmitted between synapses.

He probably thought that the author's high school biology was too bad - I was still a biology competition party back then, and I was really sorry for the competition coach back then, and I embarrassed his old man.

Since synapses are mentioned, let's seriously discuss whether the view that "there is no electric current between synapses" insisted by that brother Ren is correct.

In high school biology, synaptic vesicles transmit chemical transmitters, mainly acetylcholine, to each other, altering the permeability of the postsynaptic membrane, resulting in changes in potential.

This process is the conversion of an electrical signal into a chemical signal and then into an electrical signal.

That's it for high school biology.

But physiology is more than just high school.

In fact, there is more to a synapse than just chemical synapses – there is also an electrical synapse that directly transmits electrical signals.

In electrical synapses, the presynaptic membrane is tightly attached to the posterior membrane, through which electrical signals can pass.

So, even if this brother must understand the meaning of my sentence as "intersynaptic current", this sentence is actually true.

That's all for popular science, after that brother found out my common sense mistake, he kindly taught the author in English to be honest, and don't post it if you can't understand the literature...... Big guy, big guy, can't be provoked.

(This brother's comment has been pinned to the top in the comment area)

One last word.

The author welcomes readers to question the content of the article, but please do not take out the curriculum knowledge of middle school...... It is also very tiring for the author to write single chapters one by one to popularize science.
