> The research found that the compound increases the density of dendritic spines, small protrusions found on nerve cells that aid in the transmission of information between neurons. Chronic stress and depression are known to reduce the number of these neuronal connections. How well is the latter known? Is that consensus? Also, is it just an effect or a possible cause of depression? If it's just an effect, why would reparation be an effective treatment for depression?
