The limbic system plays pivotal role in the maintenance of homeostasis and regulation of motivation, emotion, learning and memory processes. Our investigations aim to unravel new limbic forebrain neuronal and neurohumoral mechanisms of the central homeostatic control in healthy and disease state conditions using multidisciplinary approaches such as in vivo microelectrophysiology, combined behavioral-neurochemical paradigms, molecular biology, transgenic technology, immunohistochemistry and single molecule imaging. In addition to elucidate new regulatory processes and so far unknown pathomechanisms, we believe that our research approach enables us to identify new molecular targets in the brain and opens new avenue in development of novel lead compounds. We place particular emphasis on investigations exploring the effect of steroid hormones in the basal forebrain in physiological and neurodegenerative processes. In these experiments, we study the neuroprotective effect of estrogen in basal forebrain cholinergic neurons in Alzheimer’s disease using single molecule detection microscopy and transgenic technology.
