Neuropharmacology of the mesolimbic system and associated circuits on social hierarchies
Most socially living species are organized hierarchically, primarily based on individual differences in social dominance. Dominant individuals typically gain privileged access to important resources, such as food, mating partners and territories, whereas submissive conspecifics are often devoid of such benefits. The benefits associated with a high social status provide a strong incentive to become dominant. Importantly, motivational- and reward-related processes are regulated, to a large extent, by the mesolimbic system. Consequently, several studies point to a key role for the mesolimbic system in social hierarchy formation. This review summarizes the growing body of literature that implic…
In search for predictive biomarkers: dissecting the molecular pathways in brain and blood underlying poor and good antidepressant treatment response
Major depression poses a serious social and economic threat to modern societies, as it accounts for more lost productivity compared with any other disorder. There are currently two major problems calling for innovative research approaches: 1. The absence of biomarkers predicting antidepressant response and 2. The lack of conceptually novel antidepressant compounds. Identification of biomarkers could allow patient stratification and enable the selection of pathophysiologically distinct patient subgroups to allow optimized treatment choices based on biology. In search for conceptually novel antidepressants, the hippocampal dentate gyrus is a region of particular interest, as there is a large …
