title: Opiatergic projection from the bed nucleus to the habenula: demonstration by a novel radioimmunohistochemical method.
abstract: In a modification of the indirect immunohistochemical method 125I-labeled secondary antibodies were used to autoradiographically visualize enkephalin-like immunoreactivity. Electrolytic lesions of the bed nucleus of the stria terminalis (BNST) resulted in a decrease in enkephalin-like immunoreactivity in the ipsilateral habenula. This suggests an opiatergic pathway originating in the BNST and projecting to the habenula. In addition, the value of the radioimmunohistochemical technique is discussed.
