The processing of visual information by the human brain is approached by models of neural circuits and brain mechanisms. Of particular interest are interactive and plastic changes associated with the response modifications that occur with attention, active perception and learning. A long-standing research interest is the formation of the optical image on the human retina, how it is influenced by refractive corrections and how changes may be generated by non-traditional optical procedures.
