Professor Hen's research is aimed at understanding the mechanism of action of medications that are currently used to treat depression and anxiety-related disorders. Although selective serotonin re-uptake inhibitors (SSRI) are the most commonly prescribed antidepressants and anxiolytics, their mechanisms of action, and particularly the reason for their delayed (4-6 weeks) onset of therapeutic efficacy, are largely unknown. The general hypothesis his team is studying is that the generation of new neurons from a pool of undifferentiated stem cells located in a part of the brain called the hippocampus, contributes to the delayed onset of action of SSRIs.
