Stanley Floresco

Dr. Stanley FlorescoDr. Stanley Floresco’s research focuses on neural circuits that facilitate different forms of learning and cognition, with an emphasis on the interactions between different brain regions within the dopamine system (including regions in the frontal and temporal lobes) that facilitate functions such as behavioural flexibility, cost/benefit decision making, and reward-related learning. His laboratory uses a multidisciplinary approach, combining behavioural, psychopharmacological and neurophysiological assays.

Of relevance to health-related issues, his laboratory is particularly interested in modeling dysfunction in these brain circuits and corresponding cognitive impairments associated with different diseases, such as stimulant addiction, depression and schizophrenia. The approach here is to understand how the normal brain solves these types of problems, and then assess how manipulations that model these disease states alters neural activity and behaviour mediated by these circuits. In turn, these studies further our understanding of the neural dysfunction that may underlie these disease states, and may also facilitate the development of novel treatments for these disorders.
