The Effects of Stress

In a series of studies we aim to investigate plasticity processes in response to traumatic and stressful events as well as the development of post-traumatic stress disorder (PTSD). Moreover, we wish to assess the effects of therapeutic intervention on a PTSD population and to explore novel interventions for PTSD.

In one of the largest scale studies of PTSD ever conducted using fMRI, soldiers are assessed before and after deployment to armed conflict and post-conflict zones, using a battery of neuroimaging and psychological measures. This study aims to assess whether the structural and functional changes, in particular within the hippocampal formation (Kühn & Gallinat, 2013), observed in a PTSD population are present prior to PTSD (vulnerability hypothesis) or arise as a result of the development of PTSD (acquisition hypothesis).
