title: Rats with nucleus basalis magnocellularis lesions mimic mnemonic symptomatology observed in patients with dementia of the Alzheimer's type.
abstract: College students, healthy elderly subjects, patients diagnosed with mild or moderate dementia of the Alzheimer's type, as well as rats with small or large lesions of nucleus basalis magnocellularis (NBM) were tested on an order memory task for a 6- or 8-item list of varying spatial locations. Similar patterns of order memory deficits as a function of serial order position were observed in rats with small or large NBM lesions and patients with mild or moderate dementia of the Alzheimer's type. The results provide support for the possibility that rats with NBM lesions might mimic the mnemonic symptomatology of Alzheimer's disease.
