| Research Abstract |
The rat motor thalamic nuclei are composed of ventral medial (VM), ventral anterior (VA) and ventral lateral nuclei (VL). Previously we reported that axonal arborization was different between the rostroventral and caudodorsal VA-VL neurons. In the present study, the axonal arborization of single VM neurons was examined and compared with the previous results of VA-VL neurons. In the cerebral cortex,the VM neurons sent axon fibers to more widespread cortical areas than VA-VL neurons. Of cortical layers, the axon fibers of VM neurons were most abundantly distributed in layer 1 (78%). In comparison with the previously reported data of rostroventral (54%) and cuadodorsal VA-VL neurons (5.6%), VM neurons highly preferred layer 1 to other cortical layers.
