Research interest

  • Investigation of cortical slow wave activity and delta waves in naturally sleeping animals and after treatment with different drugs.
  • Investigating the effect of cholinergic, adrenergic, serotoninergic and dopaminergic agonists on the sleep-wake cycle and auditory evoked potentials of freely moving rat.
  • Participation in testing of different drugs developed by EGIS, Richter Gedeon and Bristol-Myers Squibb pharmaceutical companies.
