Beatriz Luna, PhD is the Distinguished Staunton Professor of Psychiatry and Pediatrics as well of Professor of Psychology, BioEngineering, and Radiology at the University of Pittsburgh. She is the founder and Director of the Laboratory for Neurocognitive Development, a founder and past president of the Flux Society for Developmental Cognitive Neuroscience, Editor-in-Chief of the journal Developmental Cognitive Neuroscience, and Scientific Director of the Magnetic Resonance Research Center. Dr. Luna uses multimodal neuroimaging to investigate the neurobiological mechanisms that support the normative transition from adolescence to adulthood when lifetime trajectories are determined to inform aberrant trajectories such as in mental illness. She has received numerous awards including the Presidential Early Career Award in Science and Engineering, the Provost’s Award for Excellence in Doctoral Mentoring, and the Flux Huttenlocher Award for pioneering work in developmental cognitive neuroscience. Her research has been continuously supported by the National Institutes of Mental Health and has informed US Supreme Court briefs regarding extended sentencing in the juvenile justice system. Her extensive media history also includes a cover story in National Geographic and a PBS Special with Alan Alda – “Brains on Trial”.

In this talk, she will present the findings from a collection of her studies that provide evidence for Driven Dual Systems model that proposes that by adolescence there is availability of adult level executive processes, but they are driven by increased reward reactivity to gain new experiences needed to specialize and establish adult trajectories. She will start by presenting behavioral and neuroimaging studies (fMRI, MEG, EEG) that characterize the shape of cognitive development and the brain mechanisms that support its optimization into adulthood. Importantly, new evidence using MRSI will be presented reflecting plasticity through adolescence in prefrontal cortex. Next, she will present  findings regarding the maturation of the reward/motivation system including neuroimaging approaches that measure dopamine function (PET, striatal tissue iron) and interactions with the executive system including inhibitory control and executive function. She will finish with a broad model of adolescent neurocognitive development and implications to psychopathology.
