Abstract
The idea of the basal ganglia as a collection of functionally related nuclei is based primarily on the pattern of their synaptic interconnections. The development of this idea paralleled development of methods for studying the neuron types and synaptic connections within and among the nuclei. Progress in anatomical and electrophysiological methods in the 20th century revealed synaptic interconnections with increasing clarity and greatly increased the complexity of the known basal ganglia circuits. For decades, many of the known connections have been omitted from most functional schemes of basal ganglia function, for no reason other than to simplify the circuits.

Brain ResearchThe structural organization of layer IV in the somatosensory region (S I) of mouse cerebral cortex
2,246 Citations1970Thomas A. Woolsey, H. Van der Loos
The author describes how his methods of investigation with celloidin embedded material prepared with the Golgi method and Nissl staining revealed for the first time the “barrel fields” of the mouse cerebral cortex that are activated by stimulation of the facial vibrissae (whiskers).
The Journal of Comparative NeurologyLaminar and columnar distribution of geniculo‐cortical fibers in the macaque monkey
961 Citations1972David H. Hubel, Torsten N. Wiesel
The laminar distribution of axon terminals in the cortex is correlated with functional differences between layers, and the IVth‐layer mosaic anatomically is demonstrated.
The Journal of Comparative NeurologyRetrograde 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
881 Citations1974Elizabeth Jones, Randi Y. Leavitt
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.
Brain ResearchBilateral projections from precentral motor cortex to the putamen and other parts of the basal ganglia. An autoradiographic study inMacaca fascicularis
714 Citations1975Heinz Künzle
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.
The Journal of Comparative NeurologyAn intricately patterned prefronto‐caudate projection in the rhesus monkey
515 Citations1977Patricia S. Goldman, Walle J. H. Nauta
The results indicate that, contrary to previous reports which had suggested a projection to only the head of the caudate nucleus, area 9 of Brodmann projects to the entire length of the nucleus.
The Journal of Comparative NeurologyCells of origin and terminal distrubution of corticostriatal fibers arising in the sensory‐motor cortex of monkeys
442 Citations1977Edward G. Jones, J.D. Coulter +2 more
The cells of origin of the corticostriatal projection have been identified in squirrel monkeys by the use of the retrograde horseradish peroxidase method and are unlikely to be collaterals of axons projecting to other sites.
Brain ResearchAutoradiographic demonstration of ocular-dominance columns in the monkey striate cortex by means of transneuronal transport
437 Citations1974T. N. Wiesel, David H. Hubel +1 more
If radioactive substances were transported transneuronally, injection of labeled material into one eye followed by autoradiography of the cortex might reveal the entire system of ocular-dominance columns.
The Journal of Comparative NeurologyThe pattern of ocular dominance columns in macaque visual cortex revealed by a reduced silver stain
403 Citations1975Simon LeVay, David H. Hubel +1 more
A pattern of alternative dark and pale bands was observed in the straite cortex of the macaque monkey, observed in tangential sections stained with a reduced silver method for normal fibers.
KybernetikMotor functions of cerebellum and basal ganglia: the cerebellocortical saccadic (ballistic) clock, the cerebellonuclear hold regulator, and the basal ganglia ramp (voluntary speed smooth movement) generator
305 Citations1971H. H. Kornhuber
The conclusion is that the function of the cerebellar cortex is to calculate the burst duration for rapid preprogrammed movements, a discontinuous function, while the functions of the basal ganglia is to hold the positions reached by rapid movements precisely, a continuous regulation.
ScienceCommissural and Cortico-Cortical "Columns" in the Somatic Sensory Cortex of Primates
272 Citations1975E.G. Jones, H. Burton +1 more
Anatomical experiments demonstrate that commissural and cortico-cortical fibers arising and terminating in the somatic sensor- cortex of monkeys terminate in layers I through IV in a mosaic of precisely ordered vertical bands.
Brain ResearchMode of termination of retinotectal fibers in macaque monkey: An autoradiographic study
263 Citations1975David H. Hubel, Simon LeVay +1 more
The distribution of retinotectal projections was studied in 4 macaque monkeys by examining the tectum autoradiographically 3-21 days after eye injection with radioactive proline or a proline-fucose mixture, finding regional aggregations of input from one or other eye were to some extent reflected physiologically in a regional variation in eye dominance.
Brain ResearchAnatomical evidence for cortical subdivisions based on vertically discrete thalamic projections from the ventral posterior nucleus to cortical barrels in the rat
254 Citations1973Herbert P. Killackey
The unit in monkey striate cortex, at least with respect to eye dominance, was a long slab-shaped column of cortex rather than the vertical cylinder originally proposed by Lorente de N6, however, one possible reason for this difference not discussed is that the 'eye preference column' may not be a unitary structure.

Brain ResearchAnatomical organization of retinotectal afferents in the cat: An autodiographic study
237 Citations1975Ann M. Graybiel
In the cat, a vertical as well as horizontal organization may characterize the superficial layers of the superior colliculus, and it is likely that a somewhat comparable cluster-and-sheet organization may exist also in the deep collicular layers.
SciencePutamen: Activity of Single Units during Slow and Rapid Arm Movements
137 Citations1973Mahlon R. DeLong
Findings indicate that at least a portion of the basal ganglia (the putamen) is primarily involved in the control of slow movements and are consistent with the hypothesis of Kornhuber that the primary motor function of thebasal ganglia is to generate slow ("ramp") rather than rapid ("ballistic") movements.
