The paper identifies rod bipolar and AII amacrine cells as key to surround responses in OFF retinal ganglion cells through optogenetics and electrophysiology.

This study demonstrates that rhodopsin-based voltage indicators can be used for two-photon voltage imaging, achieving high-fidelity action potential detection in vitro and in vivo.

BiPOLES is an optogenetic tool that allows bidirectional control of neuronal activity using two different light colors, enabling both excitation and inhibition of the same neurons in a single experiment.

This paper demonstrates a method using a GRIN lens to perform precise 3D optogenetic photostimulation in vivo in mice, enabling deeper tissue penetration and multi-neuron stimulation.

The paper demonstrates that rod bipolar cells provide asymmetric input to direction selective ganglion cells, contributing to their direction selectivity through all-optical manipulation and imaging.

The paper introduces a method for high-resolution multi-cell optogenetic targeting using temporally focused light shaping in Drosophila and zebrafish larvae.

This paper demonstrates sub-millisecond optogenetic activation in mouse visual cortex using parallel holographic illumination, enabling precise control of neuronal activity with millisecond temporal resolution.
