Current research

My research focuses on quantitative morphology of prefrontal cortex from human postmortem brain tissue of individuals diagnosed with major depressive disorder, bipolar disorder and schizophrenia. In particular, the relationship between alterations in the specific subpopulation of cortical glial and neuronal cells and serotonin and glutamate neurotransmitter systems is examined by using immunohistochemical and molecular techniques. I am also interested in comparison of changes in the prefrontal cortex from depressed patients to the changes observed in the prefrontal cortex of rats submitted to chronic unpredictable stress, a well-established animal model of depression-like behaviors.
