Superdiffusive random walks decoded from mice motor neurons.

We extend our analysis to include the (a) action potential from adult mice (used threshold in red) whose (b) signal also behaves in a complex manner displaying a (c) power spectrum calculated with 2¹⁰ points with a diverse frequency content. From values of frequency satisfying we can determine (d) a fractal dust whose gaps induces a (e) 2D random walk with (f) a superdiffusive mean square displacement calculated as in Figure 2(g). (g) The number of available data points used in the power spectra calculation is not enough to detect the possible Lévy character of this superdiffusion (best fit in red).
