Research Area: Neurosciences
Research Interests: - Functional interaction of metabotropic glutamate and GABA receptors and their effector ion channels in regulation of neurotransmission.
- Studying the dynamics of surface expression and subunit composition of synapse-related proteins, as well as the activity-dependent structural changes of pre- and postsynaptic compartments in cortical principal cells and intereneurons.
- Quantitative analysis of subcellular organization of voltage-activated calcium channels in cortical and spinal cord neurons.
