A superdiffusive Lévy random walk can be decoded from a real searching task.
(a) From the temporal series of multichannel simultaneous recordings (here only a subset is shown) made from layer CA1 of the right dorsal hippocampus of three Long-Evans rats45,46, using the red threshold we can determine (b) a complex temporal behavior for the quantity 
and its (c) power spectra calculated with 217 points. (d) From the set of values satisfying 
a fractal dust is determined and from the gaps in this fractal a (e) 2D random walk is induced. (f) Its mean squared displacement calculated as in Figure 2(g), evidencing superdiffusion; while its (g) steps distribution show it is a superdiffusive Lévy pattern (best fit in red).
