Immunohistochemical Characterization of the Shell and Core Territories of the Nucleus Accumbens in the Rat

The nucleus accumbens in the rat has been parcelled into shell and core subdivisions. Despite accumulating evidence for such a division of the nucleus accumbens, these territories have not been

Relationships of the Dendritic Arborizations of Ventral Striatomesencephalic Projection Neurons With Boundaries of Striatal Compartments. An In Vitro Intracellular Labelling Study in the Rat

The present results demonstrate that the dendrites of the great majority of ventral striatomesencephalic neurons comply with the boundaries of Ventral striatal enkephalin compartments, and suggest the existence of discrete channels through the ventral mesencephalon.

The structural basis for mapping behavior onto the ventral striatum and its subdivisions

This review is focused on evaluating the structural differences in nucleus accumbens core and shell neurons and discusses how such different morphologies could underlie distinguishable behavioral processes.

Specificity in the efferent projections of the nucleus accumbens in the rat: Comparison of the rostral pole projection patterns with those of the core and shell

The efferent connections of the rostral pole of the rat accumbens were examined with the aid of the anterogradely transported plant lectin, Phaseolus vulgaris‐leucoagglutinin (PHA‐L), for comparison with the previously reported projection patterns of the accumbal core and shell, provoking the speculation that ventral striatal calbindin immunoreactive cells contribute principally to basal ganglia‐like projections.

Effects of dopamine depletion on the morphology of medium spiny neurons in the shell and core of the rat nucleus accumbens

Data suggest that the loss of dopamine can affect accumbal neuronal morphology and, moreover, can affect neuronal structures differentially in the shell and core of animals that received a unilateral, chronic 6- hydroxydopamine lesion of the medial forebrain bundle.

Evidence for a multi‐compartmental histochemical organization of the nucleus accumbens in the rat

A comparison of the connectivity patterns and neurochemical characteristics of the opioid receptor‐dense compartments in the nucleus accumbens with those in the caudate‐putamen reveals major discrepancies between these two striatal subdivisions.

Compartmental distribution of ventral striatal neurons projecting to the mesencephalon in the rat

The present results imply that through the ventral striatal compartments information from disparate combinations of cortical and thalamic sources may be conveyed to distinct mesencephalic targets.

Compartmental organization of the ventral striatum of the rat: Immunohistochemical distribution of enkephalin, substance P, dopamine, and calcium‐binding protein

In the caudate‐putamen of the rat a patch/matrix organization can be recognized on the basis of the immunohistochemical distribution of several markers, which include enkephalin, substance P, dopamine, and calcium‐binding protein, which were investigated in the nucleus accumbens.

Two transpallidal pathways originating in the rat nucleus accumbens

The present data indicate that the neurotensin immunoreactivity‐rich ventromedial district of ventral pallidum receives its accumbal input almost exclusively from the shell district of the nucleus accumbens, which is a uniquely specialized part of the basal ganglia.

Cytoarchitectonic heterogeneity of the primate neostriatum: Subdivision into island and matrix cellular compartments

According to present observations the neostriatum in primates should be viewed as a cytoarchitectonically heterogeneous structure composed of at least two distinct cellular compartments with specific connectivity related to the histochemical and functional diversity of the nestriatum.
