Fig. 1. Binary representation of the 64-bit floating-point data of a numerical simulation of the brain. Each value is expressed in a column of 64 small squares: white for a 1 and black for a 0. The first bits present high regularity (upper part of figure) while the less significant bits show high irregularity (lower part of figure).
