Journal ArticleDOI
Two methods for selective silver impregnation of degenerating axons and their synaptic endings in the central nervous system.
Robert P. Fink,Lennart Heimer +1 more
TL;DR: The original, non-suppressive Natua method for impregenation of terminal degeneration has been modified by the introduction of a potassium permanganate-uranyl nitrate sequence, resulting in a selective impregnation of degenarated axons inclusive of their synaptic thickenings.
Journal ArticleDOI
Specificity in the projection patterns of accumbal core and shell in the rat.
TL;DR: The efferent projections of the core and shell areas of the nucleus accumbens were studied with a combination of anterograde and retrograde tract-tracing methods, including Phaseolus vulgaris-leucoagglutinin, horseradish peroxidase and fluorescent tracers.
Journal ArticleDOI
New perspectives in basal forebrain organization of special relevance for neuropsychiatric disorders: the striatopallidal, amygdaloid, and corticopetal components of substantia innominata.
G. F. Alheid,Lennart Heimer +1 more
TL;DR: Consideration of morphological and connectional characteristics of basal forebrain suggests that the corticopetal cell groups, together with magnocellular elements of the striatum, serve similar functional roles for the striatopallidal system, the extended amygdala, and the septal-diagonal band complex.
Journal ArticleDOI
The afferent connections of the main and the accessory olfactory bulb formations in the rat: an experimental HRP-study.
TL;DR: The afferent connections of the main and accessory olfactory bulbs in the rat were examined by injecting horseradish peroxidase (HRP) into one or the other of these structures either by microelectrophoresis or by hydraulic pressure.
Journal ArticleDOI
Cholecystokinin innervation of the ventral striatum: a morphological and radioimmunological study.
TL;DR: The combined use of morphological and biochemical methods provided evidence for a partially overlapping distribution and possible interaction between an ascending brainstem and descending telencephalic cholecystokinin fiber systems within the striatum and related rostral forebrain areas.
