1. Caracterização dos efeitos da estimulação elétrica no núcleo basalis magnocelular no potencial de campo local e na freqüência cardíaca no condicionamento comportamental de ratos Wistar / Characterization of nucleus basalis magnocelular electrical stimulation effects on local field potential and heart rate in behavioral conditioning Wistar rats
Estudamos os efeitos da estimulação elétrica no nucleus basalis magnocelular (Meynert), núcleo colinégico que projeta aferências para o córtex cerebral e tem sido associado a mecanismos de aprendizagem e memória. Verificamos os efeitos eletrofisiológicos induzidos pela estimulação elétrica do núcleo basalis pareado com apresentação de um tom p

2. Anatomical relationship between the basal ganglia and the basal nucleus of Meynert in human and monkey forebrain.
Previous immunohistochemical studies have provided evidence that the external segment of the globus pallidus extends ventrally beneath the transverse limb of the anterior commissure into the area of the substantia innominata. Enkephalin-positive staining in the form of "woolly fibers" has been used as a marker for the globus pallidus and its ventral extensio

3. Dissociated cell culture of cholinergic neurons from nucleus basalis of Meynert and other basal forebrain nuclei.
Degeneration of cholinergic neurons from the basal forebrain nuclei is suspected to be the cause of Alzheimer disease. We have developed dissociated cultures of cholinergic neurons from these nuclei (the nucleus basalis of Meynert, the medial septal nucleus, and the diagonal band nuclei). Brain slices of the forebrains were made by a vibratome, and the basal

4. Neurotensin excites basal forebrain cholinergic neurons: ionic and signal-transduction mechanisms.
The whole-cell patch-clamp technique was used to investigate the effect of neurotensin on cholinergic neurons cultured from the rat nucleus basalis of Meynert. Neurotensin excited the neurons by inducing an initial inward current carried, at least in part, by Na+ and by reducing inwardly rectifying K+ conductance. Reduction of the inwardly rectifying K+ cond

5. Levels of nerve growth factor and its mRNA in the central nervous system of the rat correlate with cholinergic innervation.
The levels of nerve growth factor (NGF) and its mRNA in the rat central nervous system were determined by two-site enzyme immunoassay and quantitative Northern blots, respectively. Relatively high NGF levels (0.4-1.4 ng NGF/g wet weight) were found both in the regions innervated by the magnocellular cholinergic neurons of the basal forebrain (hippocampus, ol

6. Neuronal loss in the pedunculopontine tegmental nucleus in Parkinson disease and in progressive supranuclear palsy.
In the brains of humans and other mammals, there are two principal groups of cholinergic nuclei aside from those forming the cranial motor nuclei. One group lies in the forebrain and includes the nucleus basalis of Meynert. The second group lies in the hindbrain and includes the nucleus tegmenti pedunculopontinus (NPP), identified by Mesulam et al. [Mesulam,
