What I wrote was completely accurate. It's the reason why there is a campaign right now to train people on the ways to detect a stroke, because there is no feeling when you bleed in your brain. There is no pain, no warmth, no tingling, because there are no sensory receptors in the brain. None. Sensory receptors are nature's burglar alarms. You put sensors on your outer doors, and windows, and maybe in a few main hallways. The master bedroom door likely doesn't have a sensor, because once someone is there it's too late. There's little advantage to putting sensory receptors in the brain, so nature didn't.
Epileptic seizures are neural cascades that are still not well understood. What they are not is electrical, though they are sometimes dumbed down and explained that way because that is the way neural transmission is sometimes explained. There are electrochemical reactions that are involved in a seizure, because they are involved in all neural activity, but what a person who is experiencing the advance symptoms of a seizure is feeling is not electricity in the brain, but the beginnings of that neural cascade and its effects on different areas of the brain. There are as many different pre-symptoms of a seizure as there are people that experience them, though they are sometimes grouped into broad categories. Just like people who experience migraines have many different types of pre-auras (auditory, visual, sometimes olfactory). People who feel headaches feel pain not in the brain (did I mention there are no receptors there?), but in the scalp, neck, eyes, or muscles of the head.
If the person wearing this device we are commenting on here had electricity actually passing through his brain, what he would have felt are the stimulating effects on the part of the brain that the electricity was passing through. He would have seen lights, or heard something, or been hungry. What he wouldn't feel is tingling, because there is nothing in the brain that can feel tingling. There are no sensory receptors in the brain.
