Physicist's Discovery Alters Conventional Understanding Of Sight, Syracuse University Study

Published: Jun 24, 2011

A discovery by a team of researchers led by a Syracuse University physicist sheds new light on how the vision process is initiated. For almost 50 years, scientists have believed that light signals could not be initiated unless special light-receptor molecules in the retinal cells first changed their shape in a process called isomerization. However, the SU research team, which includes researchers from Columbia University, has demonstrated that visual signals can be initiated in the absence of isomerization. =
