The primary input regions to the lateral habenula (LHb) are the lateral preoptic area (bringing input from the hippocampus and lateral septum), the ventral pallidum (bringing input from the nucleus accumbens and mediodorsal nucleus of the thalamus), the lateral hypothalamus, the medial habenula, and the internal segment of the globus pallidus (bringing input from other basal ganglia structures).
In addition, the science of surface anatomy includes the theories and systems of body proportions and related artistic canons. [citation needed] The study of surface anatomy is the basis for depicting the human body in classical art. Some pseudo-sciences such as physiognomy, phrenology and palmistry rely on surface anatomy.
