Abstract
The organization of the efferent projections
of the substantia nigra following the irijection of 0.4 pl
of 2% Fluoro Gold into the caudate-putamen nucleus of
rats of both sexes was studied. After a survival period of
77 h. the greatest number of labelled cells was visuali~ed
in ihe substantia nigra, with lower numbers in adjacent
structures (ventral tegrnental area. zona incei-ta and
~rredial leinniscus).
The cclls featured an intensely fluorescent goldcoloured
soma and were varied in .shape (round or
n\:al); short sinuous projectioris arose out of thein.
corresponding to the dendrites and axons of the neurons.
ln the statistical study. no significant differences were
observed between r-iiales and females.
A sirrrilar pattern of distribution was found rangirig
Sr0111 ihe rostral to the caudal regions of the substantia
niyra. occupying the whole of the extent of the
suhstantia nigra; this distribution was most predominant
in the rostro-caudal transition of the pars compacta of
the substantia nigra.
