Director of the Laboratory for Computational Neurodiagnostics
Lilianne R. Mujica-Parodi is Director of the Laboratory for Computational Neurodiagnostics (LCNeuro). LCNeuro's research focuses on the application of control systems engineering and dynamical systems to human neuroimaging time series (fMRI, MEG, EEG, NIRS, ECOG), with neurodiagnostic applications to neurological and psychiatric disorders. Parallel development of instrumentation complements our analytical approaches by optimizing brain time series for dynamic fidelity. ( Citations )
- One of LCNeuro’s primary goals is to identify key points of failure in the regulation of neural control circuits which, depending upon how they break, lead to signs and symptoms that cluster as distinct psychiatric diagnoses. As a test case for this approach, we are working to understand how the prefrontal-limbic circuit “computes” potential threat in the face of incomplete sensory data, across a clinical spectrum that ranges from pathological fear (generalized anxiety disorder, phobia, post-traumatic stress disorder, paranoid schizophrenia) to recklessness.
- A second direction at LCNeuro considers fMRI connectivity as the solution to an optimization problem imposed, in part, by metabolic constraints at the mitochondrial scale. Theoretically, we use biomimetic modeling to predict trajectories, based on biological “rules” of energy optimization, which are then validated against data. Experimentally, we expand and contract neurons’ access to energy while observing consequent self-organization and re-organization of networks. We hope that that this work will have important implications for understanding brain aging; specifically, the epidemiologically observed impact of insulin resistance on cognitive decline.
- A third arm of our research works on maximizing signal/noise for fMRI data, using a combination of acquisition parameters and artifact-removal. Both require access to a “ground truth” for time series dynamics, which led to our invention (with Helmut Strey, Ph.D.) of a patent-pending calibration device (“fMRI dynamic phantom”), currently in commercial partnership with ALA Scientific Instruments, Inc.
