The paper compares OKR phenotypes in Frmd7 and Chrnb2 mutant mice, finding distinct effects on horizontal and vertical OKR and spontaneous eye oscillations.

The paper improves a GABA sensor, iGABASnFR2, with higher sensitivity and faster kinetics, enabling better in vivo imaging of GABAergic transmission.

The paper uses a new GABA sensor to identify over 40 GABA-releasing neuron types in the mouse retina and shows how their spatial structure and release kinetics shape inhibitory signaling.

The paper measures glutamate input kinetics in retinal starburst amacrine cells and shows that proximal dendrites have higher vesicle release rates, supporting a space-time wiring model for direction selectivity.

The paper investigates how the visual cortex processes optic flow by analyzing monocular and binocular responses in mice, finding that binocular integration underlies optic flow representation in specific cortical areas.

The paper shows direction selectivity in retinal bipolar cell axon terminals, revealing that directionally-tuned glutamatergic inputs from bipolar cell boutons contribute to direction selectivity before DSGCs.
