First-order visual interneurons distribute distinct contrast and luminance information across ON and OFF pathways to achieve stable behavior

Madhura D. Ketkar, Burak Gür, Sebastian Molina-Obando, Maria Ioannidou, Carlotta Martelli, Marion Silies

The paper shows that first-order visual interneurons in Drosophila distribute contrast and luminance information across ON and OFF pathways to maintain stable behavior under changing illumination.
