Research Description

Our laboratory aims to discover new mechanisms that contribute to the development and/or plasticity of neuronal cells. We believe that our basic research will lead to novel insights into the apparition and development of mental illnesses, like schizophrenia and bipolar disorder, and potentially help recognize original targets for pharmacological intervention and treatment.

Research Summary

The growth of neurons and their organization into circuits is a tightly controlled process that follows a series of well-defined steps. Once differentiated and integrated into networks, neurons also retain a remarkable capacity to rapidly change the arrangement of their connections in response to activity, a feature that is believed to critically support cognition as well as our ability to learn and retain information for long periods of time. Accumulating evidence strongly suggests that perturbation of the molecular interactions responsible for the growth of neurons, or the capacity of these cells to adequately respond to activity-dependent signals, contributes to the pathophysiology of different brain disorders. Our laboratory uses a multidisciplinary approach to explore these questions.
