Topic: tetrachromatic vertebrates

For many animals, color vision is important for survival, contributing to critical behaviors such as identifying food, detecting predators, and recognizing mates. How colors are processed in the central nervous system of di- and trichromatic vertebrate species (2-3 color cones) has been a topic of considerable research over the last decades. In contrast, the neuronal circuits supporting color vision in tetrachromatic vertebrates (4 color cones), such as birds, remain poorly understood. Through a combination of display engineering, large-scale Neuropixels recordings, and computational methods,

For many animals color vision is critical to make sense of their environment. Whether it's choosing the ripest fruit or identifying a potential mate, the perception of color is vital for the execution of these complex behaviors. How colors are processed in the central nervous system of di- and trichromatic vertebrate species has been topic of considerable research over the last decades. In contrast, the neuronal circuits supporting color vision in tetrachromatic vertebrates, such as birds, remain less well understood.
