Superdiffusive random walks decoded from non-motor neurons: the case of grasshopper auditory neurons.
A superdiffusive pattern can also be extracted from the (Locusta migratoria) auditory receptor (a) action potential (used threshold in red) whose (b) 
signal shows the characteristic complex fluctuations with a diverse (c) frequency content calculated with 210 points determining (d) a fractal dust with dimension, 
which gaps induce a (e) superdiffusive 2D random walk. (f) Mean squared 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).
