Séminaire – André Ramos

21 juin 2019 / 11:30

Lieu: Centre Broca Nouvelle-Aquitaine

Professor dept Cell Biology, Embryology & Genetics,
University Federal Santa Catarina, Florianopolis, Brasil

Invited by Marie-Pierre Moisan


Starting with a seminal work where we have mapped the first genomic region controlling fear-related behaviors in rats, our team developed a long-term strategy that aimed at identifying the molecular bases of anxiety-related traits and disorders. After constructing a new genetic model of anxiety (the SLA16 rat strain), its behavioral and neurobiological characterization, coupled with gene expression studies and genome sequencing, revealed a far more complex scenario, which opened new avenues to investigate a variety of processes, including learning, attention deficit and hyperactivity.
