color vision

Biologists have mapped the medulla circuitry in fruit flies, setting the stage for subsequent research on how color vision is processed.

The work will enable researchers to explore how color vision is processed in the optic lobe of the fruit fly Drosophila, providing a paradigm for more complex systems in vertebrates.

The vision system used to process color is separate from that used to detect motion, according to a new study.

The findings run counter to previous scholarship that suggested motion detection and color contrast may work in tandem.
