TLDR
The organization of the subcortical connections of caudate nucleus and putamen in the squirrel monkey was studied using horseradish peroxidase conjugated to wheat germ agglutinin as anterograde and retrograde neuronal tracer to suggest the existence of a precise reciprocal link between nigral and striatal neuronal aggregates.About:

Basal ganglia-thalamocortical circuits: parallel substrates for motor, oculomotor, "prefrontal" and "limbic" functions.
TL;DR: It now appears that at the level of the putamen such inputs remain segregated within the "motor" circuit, and it is difficult to imagine how such functional specificity could be maintained in the absence of strict topographic specificity within the sequential projections that comprise these two circuits.

Functional anatomy of the basal ganglia. I. The cortico-basal ganglia-thalamo-cortical loop
André Parent,Lili-Naz Hazrati +1 more
TL;DR: The basal ganglia circuitry is designed so as to modulate in a precise manner the neuronal activity of several brain functional systems, which are involved in the direct control of different aspects of psychomotor behavior.

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
Microcircuitry of the direct and indirect pathways of the basal ganglia.
TL;DR: The findings summarized in this commentary confirm and elaborate the models of the direct and indirect pathways of information flow through the basal ganglia and provide a morphological framework for future studies.

Functional and pathophysiological models of the basal ganglia.
Thomas Wichmann,Mahlon R. DeLong +1 more
TL;DR: Because of new data, anatomical and functional models of the basal ganglia in normal and pathological conditions (e.g. Parkinson's and Huntington's diseases) have recently come under greater scrutiny and an update of these models is clearly timely.

Amygdaloid projections to subcortical structures within the basal forebrain and brainstem in the rat and cat
J. E. Krettek,Joseph L. Price +1 more
TL;DR: The efferent fiber connections of the nuclei of the amygdaloid complex with subcortical structures in the basal telencephalon, hypothalamus, midbrain, and pons have been studied in the rat and cat, using the autoradiographic method for tracing axonal connections.
Journal ArticleDOI
The amygdalostriatal projection in the rat—an anatomical study by anterograde and retrograde tracing methods
TL;DR: Findings in additional autoradiographic material identify this relatively non-limbic striatal quadrant as the main region of distribution of the corticostriatal projection from the sensorimotor cortex.

Retrograde axonal transport and the demonstration of non-specific projections to the cerebral cortex and striatum from thalamic intralaminar nuclei in the rat, cat and monkey.
Edward G. Jones,Randi Y. Leavitt +1 more
TL;DR: The intralaminar nuclei of the thalamus have been examined particularly in the rat but with additional observations in the cat and squirrel monkey, with a view to determining the extent of their connections with the cerebral cortex and/or striatum.

The neostriatal mosaic: compartmentalization of corticostriatal input and striatonigral output systems
TL;DR: The striatal patch and matrix compartments appear to be functionally distinct and interactive parallel input–output processing channels in the mammalian forebrain.

Bilateral projections from precentral motor cortex to the putamen and other parts of the basal ganglia. An autoradiographic study in Macaca fascicularis.
TL;DR: By tracing radioactively labeled proteins transported by axonal flow, projections from area 4 to the ipsi- and contralateral neostriatum and claustrum were demonstrated in 7 monkeys, suggesting differential functions for the two striatal components in sensorimotor mechanisms.
