Four organizational levels of the basal ganglia that could be particularly determinant in terms of functional properties are reviewed and current models of thebasal ganglia are discussed.

The External Pallidum and the Subthalamic Nucleus Send Convergent Synaptic Inputs onto Single Neurones in the Internal Pallidal Segment in Monkey:Anatomical Organization and Functional Significance

The recent introduction of powerful neuroanatomical techniques combined with extracellular recordings of neurones in the basal ganglia of normal animals and experimental models of basal ganglia

The Basal Ganglia Contribution to Controlled and Automatic Processing

This chapter analyzes the involvement of the dorsal striatum in controlled and automatic processes and includes an integrative view of normal and pathological processes observed in some mental and degenerative illness.

The basal ganglia: anatomy, physiology, and pharmacology.

The Corticostriatal and Corticosubthalamic Pathways: Two Entries, One Target. So What?

This review examines and compares the anatomical and functional organization of the corticostriatal and corticosubthalamic systems, and highlights some key issues that must be addressed to better understand the mechanisms by which these two neural systems may interact to regulate basal ganglia functions and dysfunctions.

Functional Circuitry of the Basal Ganglia

The basal ganglia are proposed to be involved in the focused selection of intended movements through the multiple and parallel cortico-basal ganglia loops.

Combined neuroanatomic and neurophysiologic studies have revealed precise somatotopic organization throughout the basal ganglia system such that the leg, arm, and face areas of the cerebral cortex related to respective topographic areas within the striatum, pallidum, substantia nigra, and subthalamus.



Parallel organization of functionally segregated circuits linking basal ganglia and cortex.

The basal ganglia serve primarily to integrate diverse inputs from the entire cerebral cortex and to "funnel" these influences, via the ventrolateral thalamus, to the motor cortex.

Sagittal cytoarchitectonic maps of the Macaca mulatta thalamus with a revised nomenclature of the motor‐related nuclei validated by observations on their connectivity

Cytoarchitectonic atlas plates of the Macaca mulatta thalamus are presented in the sagittal plane of section with a revised nomenclature of the motor thalamic region based on the analysis of topographical relationships between nigral, pallidal, and cerebellar projections to theThalamus studied in 13 rhesus monkeys with the use of autoradiography technique.

Topographic organization of the ventral striatal efferent projections in the rhesus monkey: An anterograde tracing study

Topographic organization of terminal fields in the globus pallidus and substantia nigra, the projections to non‐extrapyramidal areas, the relationship between projections from the nucleus accumbens and the other parts of the ventral striatum, and the comparison between ventral and dorsal striatal projections were studied.

The neostriatal mosaic: striatal patch-matrix organization is related to cortical lamination.

The results demonstrate that the compartmental organization of corticostriatal inputs is related to their laminar origin and secondarily to the cytoarchitectonic area of origin.

The neostriatal mosaic: compartmentalization of corticostriatal input and striatonigral output systems

The striatal patch and matrix compartments appear to be functionally distinct and interactive parallel input–output processing channels in the mammalian forebrain.
