Biography
Keith Schneider, Ph.D., is a professor in the Department of Psychological and Brain Sciences at the University of Delaware, and the director of the cognitive psychology graduate program. He also is the director of the Center for Biomedical and Brain Imaging.
I study the relationship between the architecture of the human visual system and the functions of attention, perception and awareness, in both normal and clinical populations. I specialize in measuring the visual subcortex—the lateral geniculate nucleus, pulvinar and thalamic reticular nucleus in the thalamus, and the superior colliculus—using structural and functional magnetic resonance imaging. Multiple streams of information arise from distinct ganglion cell populations in the retina; the subcortical nuclei play central roles in the recurrent regulation of visual function, and here, like nowhere else in the brain, these visual streams are spatially disjoint and their activity can be measured with high-resolution functional magnetic resonance imaging. Abnormalities in these structures may be important in clinical disorders such as dyslexia. — Keith Schneider

Areas: Cognitive psychology, human neuroimaging
We are testing the magnocellular hypothesis of dyslexia, which suggests that the root cause of dyslexia may be caused by malfunctions of the magnocellular system in the brain. We are measuring the structure and function of the lateral geniculate nucleus in people with dyslexia and controls.

Using visual psychophysics, we are studying the temporal resolution and variability in normal subjects, with the aim of understanding temporal perception and illusion such as the flash-lag and Fröhlich effects.
We are measuring attentional control and modulation in the thalamic reticular nucleus and lateral geniculate nucleus.
Using population field mapping, independent components analysis and model-free clustering, we are measuring the fundamental temporal, spatial and feature-based response properties of the lateral geniculate nucleus, including its magno- and parvocellular subdivisions, and other subcortical nuclei and cortical areas.
