Disclaimer: I'm not well educated in this field, just a random curious person. I don't know anything about neural repair save that it happens while we sleep.
Anyways, the question is pretty simple: Does neural repair result in firing neurons?
Perhaps a damaged neuron being healed sometimes misfires, perhaps the little road workers that go around fixing neurons sometimes bump into things nearby and knock something loose, perhaps the processes of repairing leaves a bunch of neuro transmitters just floating in that area.. any of these could be a reason for yes.
A reason for no might be "We've studied where brain repair occurs, and where neurons are firing and there is no relation."
Any solid speculation is nice too, as long as it's offered with a grain of salt.
I'm really just looking for something better than "no clue."
