Case pg313, fig1. Soma notes a few labeled neurons also found in ipsilateral dorsal subiculum. Terminal notes WGA-HRP inj site located mainly in lateral mammiliary nucleus with a slight involvement of lateral part of medial nucleus. In addition there was some spread from the inj site site dorsally into lateral portion of SUM & lateral hypothalamus.
