Vertebrates rely on fast sensory encoding for rapid and precise initiation of startle responses. We examined short-latency startle responses (SLCs) in larval zebrafish and acquired high- speed videos of head-fixed larvae while simultaneously recording underlying field potentials. Single afferent neuron recordings from the lateral line revealed an intensity-dependent decrease in first spike latencies and their jitter, which could account for the intensity-dependent changes in timing and precision of startle response latencies.
