title: Descending efferent connections of the sub-pallidal areas in the cat: projections to the lateral habenula.
abstract: The descending efferent connections of the sub-pallidal areas to the lateral habenula were investigated in the cat using Phaseolus vulgaris leucoagglutinin (PHA-L) as an anterograde tracer. Several injections of PHA-L were made in various regions of the feline sub-pallidal regions. Subsequently, the distribution of anterogradely labelled fibres in the lateral habenula was charted. PHA-L injections into the rostral part of the sub-pallidal regions resulted in a limited number of labelled fibres in the lateral habenula, while PHA-L injections into the caudal regions of the sub-pallidum resulted in an extensive distribution of anterogradely labelled fibres in this area. Thus, the lateral habenula is an important output structure of the sub-pallidal areas in the cat.
