Lateral habenular nucleus

As described in detail by Bjorklund and Lindvall (1984), the dopaminergic fibers form a dense plexus in the lateral habenular nucleus. This contingent of innervation is concentrated in the medial portion of the lateral habenula. Bjorklund and Lindvall (1984) pointed out that substantial evidence from lesion and tracing experiments had indicated that such DA innervation originates in the A10 cell group. In the retrograde...

Expression of CBi receptors in the thalamus is low (Herkenham et al. 1991 Jansen et al. 1992 Matsuda et al. 1993 Glass et al. 1997 Tsou et al. 1998a Egertova and Elphick 2000). Regions of the thalamus with some CBi expression include the (lateral) habenular nucleus, the anterior dorsal thalamic nucleus, and the reticular thalamic nucleus (Herkenham et al. 1991 Mailleux and Vanderhaeghen 1992 Tsou etal. 1998a).
