Research focus

The research of the group is focused on the role of the hippocampus in cognitive functions involving emotional and spatial memory mechanisms. The work uses a combination of behavioral and neurochemical techniques involving studies in mice and rats.

We have been particularly interested in how chemical messengers such as serotonin and neuropeptides may modulate hippocampal cognitive functions. Another major question addresses whether disturbances in emotional memory functions are underlying depressed mood in states of major depressive disorder (MDD).Our research has demonstrated the important modulatory role of central 5-HT systems for both spatial and emotional memory. The work has also identified the critical role of multiple 5-HT-receptor subtypes such as 5-HT1A, 5-HT1B and 5-HT7 receptors in hippocampally mediated cognition. The present analysis involves studies on mechanisms behind the important interactions between 5-HT1A and NMDA-glutamate receptors as well as with muscarinic systems. A particular focus involves the signaling pathways of postsynaptic 5-HT1A receptors in vivo and how they interact with NMDA-receptor subunits important for cognition and depression.
