Plasticity in pathology

Research summary



The main goal of the laboratory is to characterize the plastic modifications of neuronal connections that underlie development and function of the central nervous system. The laboratory has a strong expertise in activity-dependent development and plasticity of the rodent visual system. Recently, the range of topics and techniques has expanded to include studies on different brain pathological conditions (stroke, brain tumors, epilepsy). A characteristic feature of the laboratory is the exploitation of specific bacterial toxins (such as botulinum neurotoxins, tetanus neurotoxin, and cytotoxic necrotizing factors) for studies of brain physiology and pathology. Our research relies on combining different electrophysiological (single unit, field potential and EEG recordings), neuroanatomical, behavioral and neurochemical approaches in vivo.



Currently, research in the lab can be divided into five themes:

  • Neural plasticity during development and neurodevelopmental disorders
  • Mechanisms of action of clostridial neurotoxins such as botulinum neurotoxin A (BoNT/A)
  • Neuroplasticity in focal stroke and effects of robotic rehabilitation
  • Novel therapeutic approaches for glioma
  • Models of seizures and epilepsy
