about anxiety

Is it possible to generate anxiety electrically or chemically?
I have read the Wikipedia article on "anxiety" and it does not explain it.
There is only a brief mention of Freud and Kierkegaard's research.
It is interesting that anxiety is related to crime, but I am more interested in the mechanism of occurrence than the treatment.
If Freud's theory according to Wikipedia is correct, he is in essence saying that where crime is allowed, people can overcome their anxiety and laugh, right?
If we can generate anxiety physiologically, it may indeed be effective in curbing crime.
Personally, I sometimes feel anxious right after a nightmare (I have a nightmare once or twice in a year), but I rarely feel strong anxiety in real life.
Anxiety is an interesting motif, I haven't had any interesting motifs lately.
I think I could pursue it.
An entry point for the exploration would be the question of whether it is possible to generate anxiety electrically or chemically.
Perhaps it is possible.
Because anxiety has intensity. But I am not an expert.
But I can guess that if it is possible to treat panic disorder with medication, it is probably possible to generate anxiety.
Does anyone know more about this?
