N-acetylserotonin, the immediate precursor to melatonin, activates the same growth circuits in the brain as BDNF (brain-derived neurotrophic factor). The results have implications for how some antidepressants function and suggest that the molecules and pathways involved in mood regulation and circadian rhythms are intertwined.

 | Although the tiny roundworm Caenorhabditis elegans has only 302 neurons in its entire nervous system, studies of this simple animal have significantly advanced our understanding of human brain function because it shares many genes and neurochemical signaling molecules with humans. Now MIT researchers have found novel C. elegans neurochemical receptors, the discovery of which could lead to new therapeutic targets for psychiatric disorders if similar receptors are found in humans. ...> Full Article |
Researchers have discovered greater levels of serotonin transporter in the brain in winter than in summer. These findings have important implications for understanding seasonal mood change in healthy people, vulnerability to seasonal affective disorders and the relationship of light exposure to mood.

 | A new thesis from he Swedish medical university Karolinska Institutet shows that the brain's serotonin system differs between men and women. The scientists who conducted the study think that they have found one of the reasons why depression and chronic anxiety are more common in women than in men. ...> Full Article |
