Single thalamic neurons which project to both the rostral cortex and caudate nucleus studied with the fluorescent...

After injections of fast blue into the rostral cortex and Evans blue into the caudate nucleus in cats, doubly labeled neurons were present in the ventral anterior, ventral lateral, rhomboid, and mediodorsal thalamic nuclei. Doubly labeled cells were also found in most members of the intralaminar group, including the central medial, paracentral, central lateral, and parafascicular nuclei. Although the centromedian nucleus contained large numbers of cells labeled with Evans blue which project to the caudate nucleus, and a few fast-blue labeled cells which projected to the cortex, doubly labeled neurons were absent from this posterior intralaminar nucleus in this study.
