title: Recovery of cortical acetylcholine output after ganglioside treatment in rats with lesion of the nucleus basalis.
abstract: The changes in acetylcholine release from the cerebral cortex induced by a unilateral electrolytic lesion of the nucleus basalis and by a treatment with GM1 monosialoganglioside (30 mg/kg i.p. for 20 days) were investigated. Acetylcholine release was measured using the cortical cup technique in rats transected at midpontine level. In the lesioned rats treated with saline an ipsilateral 38% decrease in acetylcholine release was observed. GM1 treatment prevented the decrease and brought about a 30% contralateral increase. These results indicate that GM1 induces a functional recovery of the cholinergic neurons ascending to the cortex.
