Fig. 5: Single-cell analysis of primary-neuron cultures.

a Examples for the estimation of axonal-signal-propagation velocity of one neuron, including amplitude map, latency map, the locations of the selected segments, and a linear fit to calculate the velocity for each segment. b Single-neuron-derived statistics for these primary cultures (n = 1086 neurons, data recorded from five cultures on DIV 20), including number of axonal segments, longest axon length (longest selected segments), total extension of axonal arbors (sum of all assigned segments), and action-potential-propagation velocity for all segments, average velocity for all neurons. Mean values (µ) are given as well as standard deviations (σ). Source data are provided as a Source Data file.
