Problems
edit1. This article says that the habenula's nerve impulses are transmitted TO the septal nuclei. This seems to contradict habenula, which implies that information flows FROM the septal nuclei to the habenula. Maybe it travels both ways, maybe not, but personally I get the feeling there is an error in this article (and not in habenula).
2. Speaking of habenula, this article should link to there because it contains much more detail. I've taken care of this.
Article Plans
editI will be editing Habenular nuclei for the purpose of a undergraduate seminar course. This page has very minimal information regarding the function and purpose of the brain region and does little to demonstrate how it works with other regions of the brain.
Annotated Bibliography
edit1) [1]
This article discusses the concept that the Habenula, found above the thalamus, plays an important role in regulating motivation as it relates to behavior. Divided into two sections, the medial and lateral Habenulas (MHb and LHb respectively), the LHb is the primary focus of this review, looking at its response to dopamine innervation. Focusing on studies examining cognitive and motor behaviors, researchers learned that neutral event stimuli tend to inhibit dopamine levels. Damage or dysfunction in this region led to poor impulse control, suggesting a possible explanation for behavioral responses in individuals with psychiatric disorders.
2) [2]
This review paper describes a system called the DDC (dorsal diencephalic conduction), which acts as a network for communication within the brain. The Habenula is one of three major components of this system. There is a really interesting schematic showing the interconnected pathways of the DDC as it relates to important neural structures and physiological processes such as the hypothalamus and hippocampus formation. Using rats as the predominate study model, this article gives a really good overview on the extent of influence that the Habenula has on behavior.
3)[3]
Using a zebrafish model, this study explores the effect of gene expression on the functional differences between left and right Habenula. They hoped to create a map articulating this distinction, identifying key neural pathways.
4) [4]
This study examined neural connectivity in the lamprey to explore cellular conservation of the LHb and MHb across mammals. The goal was to begin to understand if behavioral reward responses have similar physiological origins.Skd17 (talk) 21:38, 1 October 2016 (UTC)

Proposal to merge into Habenula article or split
editThis article deals with the same subject as the habenula article; the habenula is made up of the habenular nuclei, and the habenular nuclei, taken together, are synonymous with the habenula. A ↔ B.
I propose that the content of this article is either merged into the Habenula article, or that it is spun off into two separate articles for the medial habenular nucleus, and lateral habenular nucleus.
