From the Golgi-Cajal mapping to the transmitter-based characterization of the neuronal networks leading to two modes of brain communication: Wiring a…

2007

After Golgi-Cajal mapped neural circuits, the discovery and mapping of the central monoamine neurons opened up for a new understanding of interneuronal communication by indicating that another form of communication exists. For instance, it was found that dopamine may be released as a prolactin inhibitory factor from the median eminence, indicating an alternative mode of dopamine communication in the brain. Subsequently, the analysis of the locus coeruleus noradrenaline neurons demonstrated a novel type of lower brainstem neuron that monosynaptically and globally innervated the entire CNS. Furthermore, the ascending raphe serotonin neuron systems were found to globally innervate the forebrai…

Acute intermittent nicotine treatment produces a reduction in the total number of FGF-2 immunoreactive astroglial cells in the substantia nigra of th…

2004

To understand the morphological substrate of the nicotine effect on nigral FGF-2 expression, a stereological analysis of FGF-2 immunoreactive neuronal and glial profiles has been performed in the substantia nigra of the rat after acute intermittent nicotine treatment. The major finding of this paper is the demonstration that this type of nicotine treatment produces a significant reduction in the total number of nuclear FGF-2 immunoreactive astroglial profiles in the substantia nigra. A parallel analysis of nigral FGF-1 and FGF-5 immunoreactivities showed no effect of this type of nicotine treatment. The results may be explained by an inhibition of FGF-2 synthesis in a subpopulation of nigra…
