My research interest is the relationship between the architecture of the human visual system and the functions of attention, perception and awareness, both in normal and clinical populations. We have been studying the thalamus, including the lateral and medial geniculate nuclei, pulvinar and thalamic reticular nucleus, and midbrain using visual and auditory paradigms. 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 and albinism.
