Research profile:
In our research we correlate information about develop- ment and evolution of the mammalian brain. Several lines of research are presently followed in our laboratory. First, we investigate the connections of cortical fields and thalamic nuclei in various mammalian species. Next, we investigate the rate of brain cell generation and death in various orders of mammals. This information is correlated with behavioral tests, known ecological specialization and lineage history of these species. In another line of research we investigate mechanisms of seasonal oscillations of the brain volume in Sorex shrews (the Dehnel’s effect). Another area of our research concerns the role of neurotrophins in early development of the central nervous system of the laboratory opossum Monodelphis domestica. Finally, we investigate the influence of prenatal and neonatal stress in mice on brain development as well as emotional phenotype and learning abilities in adult animals
Methods:
• histology
• immunohistology
• Western blot
• tissue culture
• electroporation
• stereometry
• behavioral tests
Current research activities:
• the role neurotrophins and their receptors in early brain development in the opossum Monodelphis domestica
• influence of prenatal and neonatal stress on brain development in mice and related behavioral changes in adult animals
• mechanisms of spatial memory, fear and exploration in opossums, shrews and rodents
• adult neurogenesis in various species of mammals and its correlation with their ecology
• mechanisms and consequences of the evolutionary reduction of the size of body and brain
