The research in the Moran Laboratory focuses on parallel aims in neuroscience: to develop new neuroimaging methodologies and to investigate the neurobiology of aging.
Within the context of dynamic causal modeling—a statistical inference framework for interrogating non-invasive (functional magnetic resonance imaging, electroencephalography, and magnetoencephalography) and invasive (local field potential) neuroimages—the researchers are developing a mathematical microscope to probe fine-grained synaptic physiological details from these macroscopic recording modalities. In the development of this technology, Moran and her team rely on pharmacological, in silico, and small-animal validations and have successful initial results in humans. The approach holds promise for better understanding the active neurochemistry of brain networks that support cognition and behavior in both healthy and pathological conditions.
The scientists are applying these techniques in combination with theoretical neurobiological constructs to investigate connectivity and synaptic physiological phenotypes of age. Specifically Moran and her team are investigating whether cortical networks accrue properties such as redundancy, hyperactivation, or hypoactivation over the adult lifespan and whether particular neurotransmitters underpin such systematic changes. By investigating the neural activity supporting memory, executive function, and sensory-motor learning, the researchers are targeting their investigations to circuits that develop pathological attributes in Alzheimer’s and Parkinson’s disease.
The Moran Laboratory research goals are to identify potential fault lines in individual brains that may engender susceptibility to neurodegenerative disease and to produce translational imaging-based methodologies for better therapeutic interventions.
