Abstract :

Miriam Melis graduated in Neuroscience at the University of Cagliari where she is currently an associate professor of pharmacology. Her main research interest is to understand neurobiological mechanisms of resilience and susceptibility to neuropsychiatric disorders (e.g., substance use disorder, antisocial behavior, anxiety, depression) that involve adaptations of both mesocorticolimbic dopamine pathway and endocannabinoid system. Vulnerability to neuropsychiatric disorders can be innate (i.e., temperaments, sex) or induced by early life adversities (e.g. drug exposure, adverse social events) and can be examined in rodent models to reveal early and/or endo phenotypes in order to develop novel and age-specific pharmacological strategies for the prevention and treatment of aberrant affective functioning.
