Need help from entomologists

Colleagues expressed skepticism about the idea of applying to some entomological forum, believing that the "language barrier" would not allow them to get ANY results. They were wrong.

I am glad that stereotypes are breaking down!!! ))))))))

isolated structures...
... cockroach antennas were used

Interesting. But here comes the question. If the "antenna"is isolated, how long can it function in isolation from the organism of which it was an element?
And of course (for us, anyway), we are interested in the processes that occur in the receptors themselves, i.e. how certain interactions with the environment are transformed into electro (chemical) signals. ..

In general, I believe that technological "breakthroughs" in our time are possible only at the" junctions " of scientific research.

With the last phrase, I agree one hundred percent!!!

The antenna is isolated from the cockroach's body. At the expense of how long it can "function" I will not say, but I think that the process can be extended for some time by placing it in a nutrient medium.
As for what happens in the receptor, this is partly clear from Ivanov's article... I'll try to explain more simply: there was a contact of the receptor cell... a chemical reaction occurs with the release of a certain product... he in turn enters into another reaction, etc. As a result of all these reactions, we get a repeatedly amplified electrical impulse conducted along the nerve fiber... it is attached to the technical part of the sensor.

Interactions with the environment are chemical reactions... I'll try to post more details in the evening

Yes, no. In this article, everything is stated quite clearly, clearly and correctly.
Now the search direction is clear – how to create ("by hand") those are primary transducers (sensors) that convert chemical contact (literally with one molecule) into an electrical signal that can be detected with a sufficient degree of reliability.
This task is already for physical chemists… We'll puzzle them.
It was very important to understand how this issue was solved by Nature itself…
It is certainly possible to use the actual "natural" sensors (following Japanese scientists), but only at the first stage.
