Brain Plasticity Measured at UH (IMAGE) University of Houston Caption Valery Kalatsky, an assistant professor of electrical and computer engineering at UH, has developed an optical imaging device that creates orientation maps of the visual cortex like this one. The map shows what sections of the visual cortex prefer objects oriented to specific angles, such as horizontally and vertically aligned objects. Blue, for instance, corresponds with vertical angles, yellow with horizontal and so forth. The legend illustrates the color orientations.
