Dr. Passarotti is an Assistant Professor in the Department of Psychiatry, and is
associated with the Center for Cognitive Medicine and the Institute for Juvenile
Research at UIC. She obtained her Ph.D. in Biological Psychology at the University
of Illinois at Urbana-Champaign, where she gained an extensive background in cognitive
neuroscience, and conducted research at The Beckman Institute examining attention
processes, hemispheric specialization and interhemispheric interaction in adults
and school-age children. She also underwent a 1-year practicum in clinical
neuropsychology at UIUC. She then specialized in pediatric fMRI and brain development
as a post-doctoral researcher at the University of California, San Diego.
Dr. Passarotti has worked both with healthy and clinical populations such as
children with Bipolar disorder, ADHD, Phenylketonuria, and Williams’ syndrome.
She is interested in developing neurocognitive models of child development. To
this end, she uses cognitive and fMRI paradigms to address the fundamental question
of how the child cognition and brain mature into an adult stage, and what are the
neural bases of certain developmental syndromes. Her research can be broadly divided
into three interrelated areas, which examine the neurophysiological correlates of
both cognitive and emotional development:
• Examination of the development of the neural underpinnings of face processing and face emotion processing.
Previous fMRI research conducted by Dr. Passarotti suggests prolonged neural
development of the face processing circuitry, and progressive specialization of
the right hemisphere and fusiform gyrus for this function, that extends well into
adolescence. Current studies further examine the development of face processing
strategies, and contributions of prefrontal cortex and amygdala to face emotion
processing.
• Examination of the biological bases of Pediatric Bipolar Disorder and ADHD.
In collaboration with Dr. M. Pavuluri and Dr J. Sweeney Dr. Passarotti is examining
the neural substrate of face emotion processing, response inhibition, and language
functions in adolescents with bipolar disorder and ADHD, compared to healthy controls.
Together with the research team led by Dr Pavuluri in the “Pediatric Translational
Research in Affective and Cognitive Neuroscience and Treatment Laboratory” she is also
studying the effects of pharmacological treatment such as Lamotrigine (Lamictal),
Risperidone, and Divalproex Sodium on cognitive and emotional functioning in bipolar
adolescents.
• Examination of the development of attention processes.
Dr Passarotti is interested in examining how development of brain specialization
and inter-regional communication contribute to more efficient attention processes and
strategies. She previously found that efficient interhemispheric interaction via the
corpus callosum (the main cortical commissure in the brain, which reaches full neural
maturation in late adolescence) increases the overall attentional capacity of the brain,
across different sensory modalities. She is now extending some of her paradigms to the
developmental domain to study the contributions of interhemispheric interaction to
attention development.
