Extended Data Fig. 10: Single-unit action potential in axolotl embryonic brain development.

a, Representative average single-unit waveforms recorded from the same neurons overlaid with extremum electrodes over the 5-day recording period in (Fig. 5). b, UMAP visualization of units sorted from the continuous recording of the tail-amputated cyborg axolotl embryo, as shown in (Fig. 6). c, Firing rates of units recorded immediately before and after tail amputation of cyborg axolotl embryo, as shown in (Fig. 6). Bar plots indicate mean ± s.d., with individual dots representing firing rate of individual units, two-tailed unpaired t-test, n = 30, ****, p < 0.0001. d, Normalized presence of units sorted from continuous recording of the tail-amputated axolotl embryo, as shown in (Fig. 6).
