Huh. I have never been on antidepressants, much less discontinued one, but this brain zap seems to describe a sensation I have experienced occasionally all of my life. I never really mentioned it because it was hard to articulate and never seemed to be a problem, and no one knew what I was talking about.

Very unpleasant, lasts less than a second, felt quite like described in the article. Hearing and vision would get intense for a split second then it'd be gone. I always assumed it was a kind of very minor seizure.

I haven't experienced one in years. It seemed like I could feel one coming and short-circuit it by changing the thought I was having.
