The effect of ibotonic acid lesion of the nucleus basalis of Meynert (NBM) on the response of cortical neurons in the rat barrel cortex
In the present study, the effect of NBM lesion on the temporal characteristics of response integration evoked by multiple whisker stimulations in the barrel cortex of rats was studied. Nucleus basalis of Meynert (NBM) projects to widespread areas of the cortex and provides the major cholinergic input (80%) to the cerebral cortex. In this study we examined the effects of NBM lesion on the respon...
متن کاملInduction of a physiological memory in the cerebral cortex by stimulation of the nucleus basalis.
Auditory cortical receptive field plasticity produced during behavioral learning may be considered to constitute "physiological memory" because it has major characteristics of behavioral memory: associativity, specificity, rapid acquisition, and long-term retention. To investigate basal forebrain mechanisms in receptive field plasticity, we paired a tone with stimulation of the nucleus basalis,...

متن کاملKangenkaryu prevents the decrease of cholinergic markers following the nucleus basalis magnocellularis lesion.
The nucleus basalis magnocellularis (nbm)-lesioned rat is considered to be a model of the cholinergic dysfunction observed in the cerebral cortices of Alzheimer's disease patients. The cholinergic markers, acetylcholine release and choline acetyltransferase activity, were decreased in the cerebral cortex of the nbm-lesioned rat. Kangenkaryu (KAN), a Chinese traditional medicine, is a typical pr...
متن کاملContext-dependent responses of primate nucleus basalis neurons in a go/no-go task.
In previous studies involving monkeys performing behavioral tasks, neurons in the nucleus basalis frequently had significant changes in discharge rate when the animal made a movement in response to a sensory stimulus in order to obtain a reward. To determine whether such responses of basalis neurons are primarily sensory or motor in nature, the activity of single basalis neurons was recorded in...
