    Notes: Summary After injection of fluorescent tracer into the inferior colliculus (IC), retrogradely labeled cells were observed not only in the temporoauditory cortex (ACx) and the substantia nigra pars lateralis, but also in the globus pallidus (GP). These labeled GP cells were localized exclusively in the caudal portion of the GP, which has been known to project to the ACx. Employing a retrograde fluorescent double labeling technique, the GP-IC neurons were found to be distributed in a separate manner from the GP-ACx neurons within the caudal GP. The present study provides further anatomical evidence that the caudal GP has a functional role in auditory processing.

    Notes: Summary The localization and the transmitter phenotype of subparafascicular thalamic nucleus (Spf) neurons projecting to the inferior colliculus (IC) and to the spinal cord (Sp) were studied by using a retrograde fluorescent double labeling technique, and a combined technique of retrograde tracing and immunohistochemistry for tyrosine hydroxylase (TH) and glutamate decarboxylase (GAD). The cell population of Spf-IC neurons was totally differentiated from that of Spf-Sp neurons which have been reported to be dopaminergic. The former were densely distributed, small to medium sized cells and localized in the central portion of the Spf, while the latter were sparsely distributed, large cells and localized in the marginal portion of the Spf. Spf-IC neurons were completely devoid of TH immunoreactivity and, instead, approximately half of them showed GAD immunoreactivity. From these findings, it is concluded that the Spf is distinctly compartmentalized by the presence at least two separate neuronal subpopulations, which are distinguishable in terms of their cell size, distribution patterns, transmitter phenotypes and trajectories.
