Using the retrograde transport of horseradish peroxidase (HRP), a study has been made of projections to the ventral tegmental area of Tsai (VTA) and related dopaminergic cell groups (A 10). In order to minimise the possibility of damage to fibres of passage, a technique was evolved for the microiontophoresis of HRP such that minimal current strengths and durations were applied. In addition to a sham injection, control injections were also made to the medial leminiscus, red nucleus, deep… Expand

TLDR
In the ventral part of the midbrain, essentially separate groups of aminergic and non-aminergic neurons in both the reticular formation (VTA) and in the adjacent nuclei of the raphe project bilaterally to a variety of similar terminal fields in the telencephalon, diencephal on, and brainstem. Expand
Afferent connections of the nucleus centralis amygdalae
TLDR
The afferent input was investigated in cat by microinjecting horseradish peroxidase (HRP) into the central nucleus and examining retrogradely-labelled cells in the brain and the results were compared to other neuroanatomical studies and to functional studies of the amygdala. Expand
Efferent connections of the rostral linear nucleus of the ventral tegmental area in the rat
TLDR
The data suggest that the rat RLi is a distinct VTA component in that it projects primarily to pallidal regions of the olfactory tubercle and to their diencephalic targets, the central division of the mediodorsal thalamic nucleus and the lateral part of the lateral habenula. Expand
The cells of origin of the incertofugal projections to the tectum, thalamus, tegmentum and spinal cord in the rat: A study using the autoradiographic and horseradish peroxidase methods
TLDR
The results provide good evidence that the cells of origin of efferent projections are topographically organized and are related to cytoarchitectonic areas within the zona incerta. Expand
Projections from the intracerebellar nuclei to the ventral midbrain tegmentum in the rat
TLDR
It is noteworthy that, besides the red nucleus, the sole structures of ventral midbrain tegmentum receiving cerebellar efferents are those with a higher density of dopaminergic cells. Expand
An experimental study of the ventral striatum of the golden hamster. I. Neuronal connections of the nucleus accumbens
TLDR
Retrograde labeling was observed in the ipsilateral brainstem in cells of the ventral tegmental area and dorsal raphe and many of these projections to nucleus accumbens were found to be topographically organized. Expand

The efferent connections of the substantia innominata (SI) were investigated employing the anterograde axonal transport of Phaseolus vulgaris leuoagglutinin (PHA‐L) and the retrograde transport ofExpand
Afferents of the ventral tegmental area in the rat‐anatomical substratum for integrative functions
TLDR
Injections of the anterograde tracers Phaseolus vulgaris‐leucoagglutinin or biotinylated dextran amine into selected forebrain structures revealed a surprisingly sparse terminal arborization in the VTA, indicating an anatomical network. Expand
Projections of anterior hypothalamic neurones to the dorsal and ventral periaqueductal grey in the rat
TLDR
Double retrograde tracing studies, where the two different colour beads were injected into different subdivisions of the PAG, gave rise to very few double labelled hypothalamic neurones, indicating that neurones in the hypothalamus project to only one sub-division ofThe PAG. Expand
Cells of origin of the descending afferents to the lateral hypothalamic area in the rat, studied with the horseradish peroxidase method
TLDR
Cells of origin of the descending afferents to the lateral hypothalamic area (LHA) were examined following iontophoretic injections of horseradish peroxidase and neurons of the nucleus accumbens, olfactory tubercle, preoptic magnocellular nucleus and substantia innominata were preferentially labeled when the enzyme was deposited in the lateral part of the LHA.

Afferent connections of the nucleus raphe dorsalis in the cat as visualized by the horseradish peroxidase technique
TLDR
The present results indicate that the NRD, particularly is rostral part, receives direct projections arising from locus coeruleus complex and parabrachial nuclei, which confirm some previous reports on the afferent projections to theNRD described in the cat and rat, and indicate the richness of afferent connections of the NRd. Expand
Afferent projections to the rat locus coeruleus as determined by a retrograde tracing technique
TLDR
Following HRP injections into the rat locus coeruleus, forebrain structures containing labelled neurons included the insular cortex, the central nucleus of the amygdala, the medial, lateral and magnocellular preoptic areas, the bed nucleus ofthe stria terminalis, and the dorsomedial, paraventricular and lateral hypothalamic areas. Expand
Horseradish peroxidase tracing of the lateral habenular-midbrain raphe nuclei connections in the rat
TLDR
The present results suggest that in the rat the lateral habenular nucleus might be the link between basal forbrain inputs and the limbic midbrain area, and the raphe nuclei of the midbrain appear to be crucial regions for integrating two descending circuits. Expand
Efferent connections of the basal forebrain in the cat: The nucleus accumbens
TLDR
The results revealed the presence of a topographical organization of the projections from the nucleus accumbens to the brain stem, which indicates that the nucleus Accumbens is linked to both the limbic system and the basal ganglia. Expand
Efferent connections and nigral afferents of the nucleus accumbens septi in the rat
TLDR
The results of this study confirm earlier reports of accumbens projections to the globus pallidus and to dorsal strata of the medial half of the substantia nigra and confirm that this striatal region receives telen­ cephalic afferents from the hippocampus and amyg­ dala rather than from the neocortex. Expand
Cerebellar pathways to ventral midbrain and nigra
TLDR
It is indicated that the cerebellar nuclei connect with a continuum of cells located on either side of midline in the ventral tegmentum of the midbrain, and a lesion in nucleus fastigii results in a decrease of dopamine levels in ipsilateral forebrain. Expand
Connections of the median and dorsal raphe nuclei in the rat: An autoradiographic and degeneration study
Ascending and descending projections from the median and dorsal raphe nuclei of the midbrain were mapped in the albino rat, using reduced‐silver stains after lesions or the autoradiographic techniqueExpand
The efferent projections of the medial prefrontal cortex in the squirrel monkey (Saimiri sciureus)
TLDR
On the basis of its connections, the medial prefrontal cortex resembles the remainder of the prefrontal lobe and probably also has an important role in cortical and subcortical limbic mechanisms. Expand
Afferent projections to the cat locus coeruleus as visualized by the horseradish peroxidase technique
TLDR
The present results confirm some previous reports on the afferent connections of the LC described in the rat, cat and rabbit, and further indicate the richness of afferent projections to the dorsolateral pontine tegmental areas. Expand
Efferent connections of the septal area in the rat: An analysis utilizing retrograde and anterograde transport methods
TLDR
The dorsal septum projects to the lateral preoptic area, lateral hypothalamus, periventricular hypothalamus and midline thalamus, and amygdala, and axons arising from these cells descend through the medial forebrain bundle to terminate in a region dorsal to the interpeduncular nucleus. Expand
