Participation of brainstem monoaminergic nuclei in behavioral depression

Raphe nuclei echogenicity changes in major depression

 Background: Major depression is a common disorder with great social and individual burdens. Transcranial sonography (TCS) is a useful and noninvasive measure for assessment of normal and impaired brain parenchyma. The brainstem raphe nuclei are in close association with dorsocaudal limbic system and plays an important role in depression. In this study we compared the echogenicity of the r...

Wnt/planar cell polarity signaling controls the anterior-posterior organization of monoaminergic axons in the brainstem.

Monoaminergic neurons [serotonergic (5-HT) and dopaminergic (mdDA)] in the brainstem project axons along the anterior-posterior axis. Despite their important physiological functions and implication in disease, the molecular mechanisms that dictate the formation of these projections along the anterior-posterior axis remain unknown. Here we reveal a novel requirement for Wnt/planar cell polarity ...

Brainstem enkephalinergic projections to spinal autonomic nuclei.

The present studies in the rat employed a combined retrograde transport-immunocytochemical technique to determine the origin in the brainstem of enkephalin (Enk) projections to spinal sympathetic nuclei, including the intermediolateralis nucleus, pars principalis (ILp). We found that Enk projections to the ILp nucleus are found in such serotonergic-containing areas as the raphe obscurus; raphe ...
