摘要: Recent data of our group have shown that bilateral electrolytic lesions the nucleus basalis magnocellularis (NBM) in rats reduced escape behavior deficit occurs learned helplessness test. The present study was done to establish effect intracerebral neural transplantation on change NBM-lesioned adult male Wistar At 2 days (NBM-ET) or 10 (NBM-DT) after NBM-lesions, small fragments fetal frontal cortex (18th day gestation) were allotransplanted into lesioned NBM. Ten transplantation, test performed. number shocks animals received before making an response significantly (p < .001, compared intact control and sham-operated rats). In comparison sham-ET rats, NBM-ET showed a marked .001) increase delivered animal made such response. On other hand, NBM-DT did not show this increase. These results indicate performed at early time lesioning NBM reversed lesion exposed
