Abstract

Natural rhythm Keeping track of time is essential to many aspects of perception and cognition. Several neuronal circuits have been shown to process temporal information on very short time scales only — microseconds to milliseconds. Now Sumbré et al. report that neuronal activity in the zebrafish visual system can keep the beat of relatively slow light flashes, at regular intervals of a few seconds, for up to 20 seconds after the stimulus is removed. This type of rhythmic activity on such long time scales may be the basis for an adjustable neural 'metronome', serving as a mechanism for the short-term perceptual memory of rhythmic sensory experiences.
