Stress

We are particularly interested in the mechanisms underlying traumatic stress-induced neuropsychiatric disorders. We have adopted a juvenile-stress induced model of post traumatic stress disorder and investigate the impact of juvenile adversity on neural circuit functions of amygdala and hippocampus as well as the underlying molecular mechanisms. Our data point towards a critical role of local GABAergic interneurons and GABA synthesis mechanisms in mediating the vulnerability to stress experience.
