Studies aim to understand the cortical mechanisms underlying amblyopia.
     Funding: National Institutes of Health, National Eye Institute grant K23EY014261.
     
          In normal and amblyopic adults, past and present studies use
          psychophysical methods to study second-order spatial vision:

• contrast senstitivity
• lateral interactions
• non-linear input
• contrast discrimination
• spatial summation
• binocular summation
• first- and second-order interactions
• dichoptic masking

          Present studies use functional magnetic resonance imaging
          to study mapping of early- and high-level cortical areas,
          and first-order contrast response functions to static
          and moving stimuli in each of these areas.
