摘要
We injected biotinylated dextran amine (BDA) into single vibrissal 'barrels' of primary somatosensory (SI) cortex and reconstructed the topography of labelled varicosities in the dorsolateral caudate-putamen. Plots of labelled varicosities revealed densely-packed clusters of corticostriatal arborizations along the dorsolateral edge of the caudate-putamen and sparsely-packed arborizations more medially. The medial and lateral clusters of labelled terminals were separated by regions of unlabelled neuropil and lead us to conclude that a single cortical column sends divergent projections to multiple regions of the caudate-putamen.
