The manuscript examined the potential modulatory effects of nitric oxide (NO) on the response properties of mouse retinal ganglion cells (RGCs) using two-photon calcium imaging and multi-electrode arrays (MEA). The data identifying a group of RGCs affected by NO are solid but fall short on the precise nature of the effects and their physiological implications. The findings that there can be cell-specific adaptation effects provide useful new information for the field, and more experiments and MEA analysis are encouraged.
