Research goals and approach
Visual information from the retina targets multiple brain regions, including two image forming centers, the dorsal lateral geniculate of the thalamus and the superior colliculus. These set of connections form the primary and the secondary visual pathway respectively and have been investigated independently for decades. The flow of visual information meets at a later stage, in higher cortical areas. To this date, the respective role of each pathway remains unknown and a clear picture of the orchestrated process that is vision is still lacking. Major obstacles in understanding vision have been the lack of tools to conduct studies in awake animals, discrepancies in findings and approaches, and an oversimplified conceptual framework, in which visual information is processed linearly, from the periphery to the cortex.
