Smith-Kettlewell Brain Imaging Center
The Smith-Kettlewell Brain Imaging Center supports a wide variety of human brain imaging modalities, including MRI, MRI morphometry, functional MRI, fMR Iretonogrphy, fMRI dynamics, functional connectivity, Granger-causal connectivity, DTI, DTI tractography, whole-head EEG, EEG functional connectivity, ERG, EEG eye tracking, electroblepharography, etc. Our work centers on human visual neuroscience and computational vision, especially in the areas of human visual processing in adults, of the diagnosis of eye diseases and cortical deficits in infants and adults, on brain plasticity in relation to low vision and blindness, and on the processes of blindness rehabilitation. We are particularly interested in the normal capabilities of binocular visual processing and its disruption by forms of traumatic brain injury.
