Abstract The efferent projections of the entopeduncular nucleus (internal segment of the globus pallidus) in the cat have been studied by the autoradiographic tracing method. The findings reported in this article strongly suggest the existence of a substantial pathway originating in the internal segment of the globus pallidus and terminating in a large, circumscript region of the lateral habenular nucleus. Axons of this pathway follow a wide variety of routes to reach the lateral habenular nucleus. The implications of these findings are discussed in relation to the problem of connections between the limbic system and the corpus striatum.
