Let's see if this helps explain it. Muscle has memory (your brain is a muscle of sorts). When you start a fire with kindling you are really trying to get a small spark to start and catch to a piece of kindling right? That piece of kindling will then light and the flame will grow and continue, correct? The flame then gets bigger and hotter and continues, all from one little spark.

Seizure kindling is very similar. Your brain has one seizure, the brain "remembers" the seizure and is more likely to have another. Each seizure it has leaves it more susceptible to having another and another and another until you've got a total blaze on your mind. Does that make sense?

As for the comment of one side learning from the other that is actually what's referred to as a "Mirror Effect" not kindling. Both can definitely happen.

Kindling is pretty much what has happened in my case. I started with sp's that "grew" into cp's. I had the surgery. No seizures for several years and now some seizure activity has returned in the same lobe (what's left of it anyways). Hence the kindling effect. One tiny little spark is all it takes...

I hope this helps.
