Johns Hopkins researchers develop new imaging technology to help remove brain tumors safely

Brain surgery is famously difficult for good reason: When removing a tumor, for example, neurosurgeons walk a tightrope as they try to take out as much of the cancer as possible while keeping crucial brain tissue intact — and visually distinguishing the two is often impossible.

UC Davis' John S. Werner wins 2015 Verriest Medal from International Colour Vision Society

John S. Werner, a UC Davis neuroscientist and international authority on visual perception, has been selected to receive the 2015 Verriest Medal from the International Colour Vision Society for his contributions to understanding the structural and functional basis of color vision, how and why vision changes across the life span, and factors that contribute to loss of vision associated with disease. He will receive the award at the society's biennial symposium in Sendai, Japan, in July.
