Beyond Colour Vision: Ancestral Photoreceptor Diversity as the Basis of Visual Behaviour

01.10.2025 bis 30.09.2027

Mice use both M, M/S, and “true" S cones in natural daylight, but the role of "true" S cones beyond color vision remains unclear. We hypothesize that "true" S cone signals, via distinct circuits, drive specific behaviors and test this by recording behavior under different light spectra and performing functional retinal recordings in wild‐type and "true" S cone‐knockout mice. Our aim is to clarify the evolutionary role of these spectral channels and their influence on mouse behavioral state.
