Neurobiology of autism

Dr. Lainhart's research focuses on understanding brain growth, development, and maturation in autism from the fetal period into adulthood. She leads a multidisciplinary research group that is conducting a longitudinal neuroimaging study of the brain in autism. High-resolution structural MRI, diffusion tensor MRI, functional MRI, fetal ultrasound, and birth and early childhood head circumference data are integrated with clinical and neuropsychological data. The goals are to define brain phenotypes of autism from the prenatal period into adulthood and understand how changes in brain structure and function and white matter microstructure are related to clinical symptoms, course, and outcome. The research is funded by the National Institutes of Mental Health.
