| Abstract: | The substantia nigra pars lateralis (SNI) of the rat was found, by the anterograde and retrograde tracing methods, to send projection fibers to the peripheral shell region surrounding the central nucleus of the inferior colliculus (IC), bilaterally with a clear-cut ipsilateral dominance. SNI neurons sending their axons to the IC were distributed throughout the entire rostrocaudal extent of the SNI. None of these SNI neurons showed tyrosine hydroxylase-like immunoreactivity. |
