To perceive events as simultaneous despite differences in how sensory signals are generated and transmitted, the brain must preserve temporal coherence. We found that retinal ganglion cells adjust the speed with which they transmit neural signals, revealing a mechanism in the human retina to keep visual perception precisely timed.
