Abstract: | Summary Histochemical staining for a mitochondrial enzyme, cytochrome oxidase demonstrates elongated, rod-like configurations of probable axon terminals in the trigeminal representation of the monkey somatic sensory thalamus. The stained rods are colocalized with similar aggregations of immunocytochemically stained GABAergic thalamic interneurons. Other data suggest the rods also contain clusters of relay neurons projecting to cortical columns, and they are here demonstrated as somatotopic units by micro-electrode mapping and the distribution of afferent fibers. Similar somatotopic rods can be revealed in the rest of the thalamic body representation by the reduction in cytochrome oxidase staining ensuing from the cutting of selected peripheral nerves. |
