One major area of interest aims at analyzing and cross-linking personality with the stress response. The personality variables self-esteem and locus of control have been shown to systematically affect the perception of stress. These studies also seem to systematically link the hippocampus to both individual differences in stress responsivity as well as the stress response.
The research team also investigate the endocrinological aspects of the Hypothalamic-Pituitary Adrenal (HPA).
Both structural and functional brain imaging techniques are used at the lab.
- Structural imaging: Use of recently developed protocols that allow manual segmentation of frontal and medial temporal lobe structures. Here, the interest is in morphological processes that are associated with cognitive decline, normal aging and hormonal dysregulations in non-clinical and clinical populations.
- Functional imaging: Use of both Positron Emission Tomography and functional Magnetic Resonance Imaging to investigate the effects of acute and chronic stress on the brain.
