Maria L. Medalla, PhD

Associate Professor, Boston University Chobanian & Avedisian School of Medicine

Biography

Dr. Medalla’s work combines cellular in vitro electrophysiological methods with multi-scale anatomic techniques to understand the biophysical and synaptic properties of neurons within prefrontal cortical (PFC) networks in non-human primate and rodent animal models. Her expertise includes patch-clamp recording, pathway tract-tracing, multiple immunohistochemical labeling techniques for light and electron microscopy (EM), 3D serial EM, and confocal microscopy. The major goal of her work is to understand how distinct limbic, sensory and motor networks interact and are controlled by the PFC – the central executive of the brain. Her current focus is on the medial prefrontal anterior cingulate cortex (ACC) in rhesus monkeys, an area important for attention, emotions and context-to-action transformations, and is selectively disrupted in many affective disorders such as depression and anxiety disorders.
