Research profile:

Cellular, molecular and systemic mechanisms of neuroplasticity are explored in three experimental models:

  • learning-induced plasticity in somatosensory  barrel cortex of rodents. We investigate the role of GABA-ergic inhibition in modifications of cortical sensory representations by learning
  • reorganization of cerebral cortex after stroke and during ageing. Using mouse model of photothrombotic stroke localized in the vicinity of somatosensory cortex, we  investigate the effectiveness of different anti-inflammatory interventions in preserving functional cortical  plasticity in the acute post-stroke period
  • plasticity of adult cat visual cortex after lesions of central retina, an animal model of brain reorganization after macular degeneration


Current research activities:

  • optical recording of vibrissae representations in brain cortex; observations of learning induced plasticity
  • live imaging of axons of somatostatin interneurons in brain cortex after learning and in the aging brain
  • investigations of the role of somatostatin  and VIP interneurons in learning-induced plasticity using chemogenetic tools
  • investigation of participation of electrical synapses in learning-induced plasticity of the barrel cortex
  • examination  of the motion processing pathway involvement in restoration of cortical activity in cat brain after binocular lesions of central retina using behavioral tests, MRI spectroscopy and DTI techniques
