Spectral inference reveals principal cone-integration rules of the zebrafish inner retina

The paper uses spectral responses of bipolar cells in zebrafish to infer integration rules in the inner retina, revealing six dominant spectral motifs and a new axis of spectral opponency.

Colourfulness as a possible measure of object proximity in the larval zebrafish brain

The paper shows that larval zebrafish have imbalanced On- and Off-responses to different light wavelengths, which may enhance their ability to detect object colorfulness and proximity.

Ancestral circuits for vertebrate colour vision emerge at the first retinal synapse

The paper reveals how larval zebrafish retinal circuits process color by rotating spectral information into primary achromatic and chromatic axes at the first synapse, a strategy also used by fruit flies.

LED Zappelin': An open source LED controller for arbitrary spectrum visual stimulation and optogenetics during 2-photon imaging.

The paper introduces an open-source LED controller for spectrally arbitrary visual stimulation and optogenetics during 2-photon imaging, demonstrating its use in zebrafish and Drosophila experiments.

Divergent excitation two photon microscopy for 3D random access mesoscale imaging at single cell resolution

This paper introduces a new two-photon microscopy technique that expands the 3D field of view while maintaining single-cell resolution, enabling more comprehensive neuronal activity imaging in multiple organisms.

An arbitrary-spectrum spatial visual stimulator for vision research

This paper introduces a flexible spatial visual stimulator with arbitrary spectrum control for use in vision research, demonstrating its application in mouse and zebrafish models.
