Mitochondrial Physiology and Pathophysiology in CNS

You are here:

Research Focus

  • Activity dependent changes in neuronal energy metabolism
  • Contribution of free radical dependent mechanisms to abnormal network synchronization in epilepsy and schizophrenia
  • Alterations of neurometabolic and neurovascular coupling during recurrent seizure activity
  • Mechanisms of pharmacoresistance in temporal lobe epilepsy

Methods

  • Combined electrophysiological and live cell imaging applications by using
         Whole cell patch clamp recordings
         Local field potential, oxygen and ion-sensitive electrode recordings
         Laser-scanning and multiphoton confocal microscopy
         Post hoc immunofluorescence labeling and reconstruction
  • In vitro models of epilepsy/gamma oscillations/microvasculature by using acute brain slices and slice cultures

Funding
