} The reason I'm asking about a lesion is that they claim there is a
} long-lasting (maybe permanent) increase in seizure threshold akin to
} kindling's permanent lowering of seizure threshold.
You're wise to ask again. You've received a non-answer from our
resident motor mouth.
I can find no direct answer to your question in the literature. The
closest I can find are references to use of DC current with respect to
other damage. Depending upon polarity, it can help or hinder.

A change in seizure threshold could well be due to a change in
response to GABAergic interneurons. A possibility is disruption of
interneuronal gap junctions...

On the other hand, you have in your possesion the paper that refers to
it. At least one of the authors is listed as a contact, probably via
email. They wouldn't do that if they didn't welcome good questions.
