Background and Interests
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.
