Cognitive and behavioral neuroscience

Modeling of executive functions and behavioral traits related to mental disorders in rodents

Research axis:

  • Animal models of mental disorders
  • Cognition and behavior
  • Motivation and emotion
  • Decision-making and executive functions
  • Behavioural pharmacology
  • Neurobiology
  • Neurological and psychiatric conditions

Scientific expertise:

  • Dimensional approach in rodents, based on the idea of a continuum between normality and pathology, for the modeling of mental disorders
  • Inter-individual differences in rodent’s cognition and behavior
  • Rodent’s behavior : cognitive and conative processes, executive functions
  • Behavioral traits and related neurobiological inter-individual differences in neural network activation during behavior
  • Identification of neural signatures of behavioral traits through monoamine basal levels and metabolisms
  • Validation of cognitive tasks analogous to human tasks (impulsivity, decision-making)
  • Modeling in rodents of ADHD, impulsivity, inflexible behavior, poor decision-making, poor working memory


  • Functional and dynamical organization of the networks involved in good vs poor decision-making by functional imaging (c-fos, zif) (coll. C. Le Moine, addicteam) and neurochemical correlates of these differences (monoaminergic systems) (coll. P. de Dewaerdere, IMN, Univ Bordeaux)
  • Computational modeling of inter-individual differences in decision-making and related behavioral and cognitive traits (coll. P. Seriès et V. Valton, Univ. Edinburgh ; A. Marchand, INCIA)
  • Characterisation of behavioral traits associated with poor decision-making and identification of risk-factors for developing addiction to drug (cocaïne, nicotine), coll. with M. Cador and S. Caillé Garnier (addicteam).
  • Behavioral and neurobiological characterization of the protracted abstinence state in rat with drug exposure either in adolescence or in adulthood
