Christina Ledbetter, PhD


Dr. Christina Ledbetter is a clinical neuroscientist and researcher with a PhD in pharmacology, toxicology, and neuroscience. She specializes in functional Magnetic Resonance Imaging (fMRI) and brain mapping for surgical planning. She is a research fellow in the Department of Neurosurgery at LSU Health Sciences Center in Shreveport, LA where she is the Director of the Clinical Neuroimaging Lab. Her research expertise is applied to neurological conditions including cognitive impairment, Parkinson’s disease, epilepsy, brain tumors, and traumatic brain injury. With a background in both medical imaging and neuroscience, she is an expert at using fMRI to assess changes in the brain following neuroplasticity-based interventions with a particular interest in the Default Mode Network (DMN) and the correlation of changes in network connectivity with changes on neuropsychological testing measures.
