Epilepsy that does not respond to drugs can be halted in adult mice by transplanting a specific type of cell into the brain, UC San Francisco researchers have discovered, raising hope that a similar treatment might work in severe forms of human epilepsy.
UCSF scientists controlled seizures in epileptic mice with a one-time transplantation of medial ganglionic eminence (MGE) cells, which inhibit signaling in overactive nerve circuits, into the hippocampus, a brain region associated with seizures, as well as with learning and memory. 
Epilepsy is one of the most interesting human diseases.
The problem of the patient is not that his brain is not working, but rather that it is working too much! And it is really bad (and characteristic of today’s mentality) that official research has gone into the path of trying to find how to inhibit this activity, rather than understand it and harness it’s power…
Accept “crazy”. Progress forward.
