Team:
Organization and Adaptability of Motor Systems (Organisation et Adaptabilité des Systèmes Moteurs - OASM)

Domain:
Functional organization and plasticity of neural networks

Research interests:

  • Neurobiology of emotion
  • Neural organization of locomotor-related behaviors
  • Regulation and development of sensory-motor networks

Scientific expertise:

  • Electrophysiology: extra/intracellular recordings, electromyography
  • Kinematics and behavioral analyses
  • Oculomotor and locomotor neural networks
  • Oculomotor and locomotor behaviors
  • Social behavior, agression, anxiety

Projects:

  • Developmental adaptation of networks controlling locomotion and gaze during frog metamorphosis
  • Central and sensory-motor mechanisms of movement control in crayfish
  • Neural networks of "emotion" in arthropods
  • Hormonal control of emotion and reconfiguration of neural network during growth
  • Role of serotonin in neural network reconfiguration after social interactions
