Figure 3. Stability of evoked latency on repeated stimulation.

The ‘latency jitter’ of dorsal horn cells at P3, P6 and P10. Latency jitter is the variation in the response latency recorded from an individual cell, when comparing the evoked response to each stimulus in the train (16 stimuli at 0.5 Hz). This is different from the variation in latency of the whole-cell population at a specific age (Fig. 2). ▪, cells in the superficial dorsal horn; ○, cells in the deep dorsal horn.
