Team:
Hybrid Sensorimotor Performance

Domain:
Development of arthropods : hormones and behavioral plasticity

Research axis:

  • Modulation of social behavior by ecdysteroids (molting hormones) in crayfishl;
  • Interactions between ecdysteroids and serotonin in the regulation of crayfish behavior
  • Hormonal control of aggression
  • Relationships between crayfish behavior and neural network sensitivity to hormones and neuromodulators

Scientific expertise:

  • Arthropod development, reproduction and behavior
  • Ecdysteroids
  • Biochemistry and analysis of arthropod hormones
  • Serotonin biosynthesis

Projects:

  • Interactions between ecdysteroids and serotonin in the behavioral plasticity of crayfish
  • Aggression in crayfish : consequences for animal development and for species expansion
  • Reconfiguration of locomotor neural networks by ecdysteroids and serotonin during molts (with Dr. D. Cattaert)
