ABSTRACT
Pilocarpine-induced status epilepticus leads to widespread limbic forebrain damage in rats and provides a model for studying intractable epilepsy. Noradrenergic neurons in suspension, prepared from the locus coeruleus region of donors on the 13th or 14th gestational day, were microinjected bilaterally into the hippocampus (8 rats) and into the cerebellum (4 rats) or the olfactory bulb (4 rats) of epileptic rats. Three µ1 of suspension was deposited at the rat of 1 µl/min. Control animals were not submitted to surgery (4 rats). After six weels a marked reduction of suppression of spontaneous seizures was observed in intrahippocampally grafted rats. from these preliminary results we suggest that frafts can be used to suppress spontaneous recurrent epleptic seizures
