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.

Heinen Lab
Our laboratory studies eye movements to understand basic neural circuitry that moves the eyes for clear vision, and as a tool to probe mental processes that are distinctly human. Our ultimate goal is to understand the substrate of neurological function and dysfunction, leading to development of non-invasive diagnosis and therapy for brain trauma and psychiatric disorders.

ActiveSpectral ERG analysis of hypersensitivity to light in traumatic brain injury
The purpose of this research study is to use the spectral electroretinogram (ERG) to deteremine how the retinal mechanisms of sufferers from abnormal light sensitivity due to head injury differ from those without abnormal light sensitivity.

ActiveSL-CN: Harnessing the Power of Drawing for the Enhancement of Learning across Levels of Vision Function
This Science of Learning Collaborative Network brings together researchers and experts from the Smith-Kettlewell Eye Research Institute, University of Bamberg (Germany), Columbia University and Emory University to investigate how the visual art of drawing can enhance learning. Underlying learning principles and neural mechanisms will be considered, and how these can be harnessed for real-life learning enhancement. Though humans have been drawing for at least 30,000 years, little is understood about brain processes involved in this activity.

ActiveMechanisms of Photophobia in Mild Traumatic Brain Injury in Human Subjects: Therapeutic Implications
The purpose of this grant is to identify the mechanisms responsible for generating photophobia in patients who have suffered mild traumatic brain injury (mTBI). Currently, estimates indicate that this painful condition persists in about 60% of those who suffered from blast-related traumatic brain injury and 30% of those who suffered non-blast-related concussive injuries.

Advanced Spatiomotor Rehabilitation in Blindness and Visual Impairment
We propose a multidisciplinary approach to effective spatiomotor rehabilitation in blindness and visual impairment. For those who have lost vision, the eye-hand coordination normally available for the manipulation of objects for everyday activities is unavailable and has to be replaced by information from other senses
