This paper evaluates fluorescent nanodiamond phantoms as a robust benchmarking tool for spatial resolution in two- and three-photon microscopy, showing they better capture depth-dependent optical degradation than conventional bead phantoms.

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.

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.

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.

The paper characterizes retinal ganglion cells (RGCs) in larval zebrafish, revealing UV-responsive RGCs and complex color opponency, suggesting a dual-achromatic visual strategy for prey capture and color vision.

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.
